When liquid water from oceans and seas evaporates, it forms clouds in the sky. The wind pushes these clouds over land, where the water vapor condenses and becomes rain or snow. Some of the rainwater joins rivers and flows down to the ocean or sea, completing the cycle.

Some of the world’s water is held as a solid, called ice, and this is also part of the water cycle. When the ice on cold mountaintops melts, liquid water flows into rivers and returns to the sea.

What Is the Water Cycle?

Water flows over rocks in a river.

Water is the most important element on Earth. It flows over the surface, under the ground, into the air, and inside of every living thing. Made of two parts hydrogen and one part oxygen, water can be solid, liquid, or gas.

Oceans, lakes, and ponds are water. Rivers and streams are too. Water can fall as rain, sleet, or snow, and freeze into ice sheets, icebergs, and glaciers. Humidity, fog, and clouds are water too.

All of the water on Earth makes up the hydrosphere. The hydrosphere is nearly a closed system-the water you drink today is the same that existed during the time of dinosaurs. Nothing living can exist without water.

Water is important, but so is the cycle that controls it. The water cycle has no beginning or end, moving water from Earth's atmosphere to the surface and then back again. Water changes from solid, liquid, and gas as it cycles.

Hydrologic Cycle

rduan32_1 — 2025-04-23 17:26:55 UTC

The evaporation, precipitation on land, and eventual return to the sea of this water is known as the hydrologic cycle. Heat from the sun drives the various interrelated processes. Differential heating of the surface creates atmospheric weather patterns that carry water evaporated from the oceans. The water is transported to different parts of the surface, where it precipitates as either rain or snow. A large percentage of the water falls back into the oceans, but a significant amount, 37,000 cubic kilometers annually, falls onto land surfaces. This quantity of water, flowing down from the average continental elevation of 2,700 feet (820 meters), has a potential energy of over 12 billion horsepower.

How glaciers form

mmcmahon32_2 — 2025-04-23 17:28:59 UTC

Glaciers are formed when snow is packed down into ice. Snow crystals accumulate year by year in areas where the temperatures never become high enough to completely melt the snow and ice. When a large amount has accumulated, the snow is under great pressure from the weight. Eventually the snow becomes packed so tightly together that it turns into ice.

Glaciers

kmehta32 — 2025-04-23 17:29:21 UTC

Glaciers only form in certain climates. They have to be above geographic snow lines. Snow lines separate snow accumulation and snowmelt. Snow does not melt north of a snow line. It accumulates year after year. Snow falls heavily during winter. It does not melt during summer. Summers above the snow line are short. Cool temperatures preserve the snow.

Glaciers are slow-moving rivers of ice. They form when more snow falls than melts. Snow accumulates and compacts over thousands of years. It eventually turns into solid ice. The ice becomes a glacier when it starts to move. Glaciers move from the pressure of their own weight. They flow downward with gravity.

Glaciers are an important part of the hydrosphere. Glacial ice is the second-largest source of water on Earth. Besides the ocean, ice holds two times more water than every other water source on Earth combined. The volume of glacial ice could sustain all of the planet's rivers and streams for 1,000 years.

Glaciers also hold most of Earth's freshwater. Although oceans hold 97 percent of Earth's water, seawater is salty. Three percent of water on Earth is fresh, and two percent is frozen in glaciers. Ice is always made of freshwater. Salt won't freeze with water crystals, so when salt water freezes, it loses its salt.

Types of Glaciers

rduan32_1 — 2025-04-23 17:30:39 UTC

There are two main types of glaciers—alpine and continental. Alpine glaciers are formed in the mountains. There are several different kinds of glaciers in this category. A valley glacier, one of the most common, is a long, narrow mass of ice that fills the valleys of high mountains. Piedmont glaciers are formed when a number of valley glaciers unite and spread out upon a plain at the foot of a mountain range. Alpine glaciers are found on every continent except Australia. Continental glaciers are also called ice sheets. They are found on Greenland and Antarctica.

water cycle

lmakarov32_1 — 2025-04-23 17:31:31 UTC

Evaporation

The sun is what powers the water cycle. The warmer the water, the faster it evaporates. Evaporation is an important part of the water cycle.

Evaporation turns liquid water into a gas called water vapor. In the process, the bonds between different water molecules are broken. Purified water vapor rises into the atmosphere, leaving salt and sediment behind.

Ninety percent of evaporation occurs on the surfaces of large bodies of water. Oceans have the largest surface area, covering more than 70 percent of the planet. They absorb most of the sun's energy and, in turn, release the most evaporated water into the water cycle.

Evaporated water spends about 10 days in the air. If evaporation happens quickly, the air will become humid. Humid air contains a lot of water. It feels warm, wet, and heavy. On the other hand, dry air is able to hold more evaporated water. Areas with low humidity and warm temperatures are most effective at absorbing water vapor.

Condensation

Water vapor condenses as temperatures drop.

Condensation is the opposite of evaporation. It turns water vapor back into liquid water.

After evaporation, water vapor rises high into the atmosphere. Air pressure and temperature drops the higher the vapor gets. This cools the water vapor. The water vapor clings onto particles of dust, smoke, and salt in the air, changing the vapor into droplets.

The droplets group together to form clouds. However, they are still too small to be seen. As more vapor condenses, the cloud droplets grow in size. An enormous group of cloud droplets make the clouds we see in the sky.

There are many different kinds of clouds. The shapes they take give them their names. Cirrus clouds are thin, white, and wispy. Stratus clouds form thick layers of gray. Altostratus clouds cover the sky. Cumulus clouds are thick and grow upward. They have dark bases with mounds of white puffs. When cumulus clouds produce rain they are called cumulonimbus. They are often thunderstorms, dark and heavy with rain.

Wind pushes clouds upward, increasing the cloud's humidity. Condensation accumulates until it is heavy enough to fall. It takes millions of cloud droplets to form a single drop of rain. But finally, that raindrop falls back to Earth as precipitation.

Precipitation

A heavy rain soaks the ground.

The water that falls back to Earth is called precipitation. Rain, hail, snow, and sleet are all forms of precipitation.

Precipitation falls as rain when temperatures are above 32 degrees Fahrenheit (0 degrees Celsius). Rainfall can be a gentle mist or a dangerous storm. Water returns to Earth most often as rainfall.

When temperatures are below freezing, precipitation falls as snow, sleet, or freezing rain. Snow is made of frozen ice crystals and falls in loose flakes. Every snowflake has a different design. However, most are shaped like hexagons. Sleet is falling snow that melts and refreezes before reaching the ground. Freezing rain occurs when snow melts as it falls through warmer air and then refreezes on surfaces that are below freezing.

Hail is frozen water that falls as hard chunks or solid ice. It almost always forms in cumulonimbus clouds. This is because tall, tower-shaped cumulonimbus clouds reach higher elevations in the sky, where the air reaches below-freezing temperatures.

Precipitation is an important part of the water cycle. It replenishes freshwater on Earth. Frozen precipitation accumulates as snow or ice. Rainwater soaks into the ground or runs off, forming lakes, rivers, and reservoirs.

Collection and Storage

Lake Tahoe is located on the Nevada-California border.

Reservoirs collect and store water. Some water is stored for thousands of years. Reservoirs are found on Earth's surface as oceans, lakes, rivers, glaciers, and ice caps. They are also found underground as aquifers.

Oceans are the largest reservoirs. They store almost 97 percent of the water on Earth. Their waves, tides, and currents are constantly moving, mixing water, and carrying warmth and nutrients to every corner of the world.

Wind energy pushes surface water, making waves. Tides are long waves that follow the moon's gravity. They affect the movement of the entire ocean, causing sea levels along the shore to rise and fall every day. Currents move like rivers within the ocean. They travel around the world, mixing warm and cold water. Currents flow in huge circles called gyres. Earth's rotation spins gyres in different directions. Gyres spin clockwise in the Northern Hemisphere. Western currents move warm water from the equator to the icy poles. In the Southern Hemisphere, gyres spin counterclockwise. Eastern currents move cold water toward the warmer equator.

Oceans are very important to the water cycle. But freshwater is what keeps life on Earth going. Yet freshwater makes up only about 3 percent of all water on Earth. Freshwater is stored on Earth's surface as lakes, ponds, rivers, streams, and glacial ice. Lakes are large bodies of freshwater surrounded by land. They are continually replenished by the water cycle.

Ponds are small, shallow lakes that are also freshwater reservoirs. Because they are so shallow, their temperatures change with the weather. The temperature at the pond's surface is the same at the bottom of the pond. Ponds also evaporate faster than lakes. Some dry up completely.

Rivers carry water downstream.

Rivers and streams also have an important role in the water cycle. Water runs downhill into rivers, draining the landscape. Rivers work like roads, spreading across continents and carrying precipitation back to the ocean.

Sometimes water is stored for a long time before it moves to the next part of the water cycle. For example, seawater might freeze on the surface of the ocean, leaving salt behind and becoming freshwater. These floating icebergs have an added benefit. They act as an insulator and protect the water below from freezing.

Margerie glacier in Alaska

Glaciers store an enormous amount of freshwater. They are often found at high elevations on mountains where more snow falls than melts. The snow compacts and turns into solid ice.

Glaciers are slow-moving rivers of ice. The pressure of their own weight moves them along the mountainside, carving depressions into the landscape. Later, water will collect in these depressions. Greenland and Antarctica are Earth's largest glacial ice sheets.

Ice is important to the water cycle. If all the glacial ice on Earth melted, sea levels would rise by 230 feet (70 meters). Entire countries would be underwater. Millions of people would have to move to higher ground. There would be less land for crops, less drinking water, and more pollution. Pollutants formerly stored in glaciers are released as the ice melts, flowing into lakes and rivers. People and animals would eventually starve.

Melting ice would change the ocean too. Sea levels rise, threatening coastal cities and other low-lying areas. Currents change, affecting ocean temperatures, salinity levels, and nutrients for sea life. Earth needs ice for life to survive.

Infiltration

Water soaks into the soil and is filtered. It then is sometimes accessed through a well.

Infiltration is when water is absorbed into the ground during and after precipitation. Infiltration is measured by the amount of water that soaks into the soil, sand, or stone per hour. Groundwater is naturally filtered as it flows slowly through the earth.

Groundwater is almost everywhere. Billions of gallons are stored deep underground. Some has been in its liquid state for millions of years. Because it does not receive heat from the sun, it does not evaporate. This mean it moves through the water cycle much slower than surface water. But eventually it finds openings, refilling wells and underground pockets called aquifers. It also bubbles and flows out of the earth as freshwater springs.

Sometimes water freezes with sediment, becoming permafrost. Permafrost is water-soaked soil that has been frozen for more than two years. This happens in colder climates where temperatures are often below freezing.

Glacier is a large mass of ice that flows slowly under the influence of gravity. Glaciers consist of packed snow that has built up over many years. The snow's weight eventually compresses its lower layers into ice. Glaciers scrape the ground as they move over it, eroding old landforms and creating new ones. They range in thickness from several feet or meters to 10,000 feet (3,000 meters) or more.

Water covers 70% of our planet, and it is easy to think that it will always be plentiful. However, freshwater—the stuff we drink, bathe in, irrigate our farm fields with—is incredibly rare. Only 3% of the world’s water is fresh water, and two-thirds of that is tucked away in frozen glaciers or otherwise unavailable for our use.

As a result, some 1.1 billion people worldwide lack access to water, and a total of 2.7 billion find water scarce for at least one month of the year.

Climate change is making water scarcity worse. The impacts of a changing climate are making water more unpredictable. Terrestrial water storage – the water held in soil, snow and ice – is diminishing. This results in increased water scarcity, which disrupts societal activity.

As a result, some 1.1 billion people worldwide lack access to water, and a total of 2.7 billion find water scarce for at least one month of the year. Inadequate sanitation is also a problem for 2.4 billion people—they are exposed to diseases, such as cholera and typhoid fever, and other water-borne illnesses. Two million people, mostly children, die each year from diarrheal diseases alone.

We use water in our homes for cleaning, cooking, bathing, and carrying away wastes. We use water to irrigate dry farmlands so we can grow more food. Our factories use more water than any other material. We use the water in rushing rivers and thundering waterfalls to produce electricity.

-we are using too much!!!!

There is the same amount of water on Earth as there was when the Earth was formed. The water from your faucet could contain molecules that dinosaurs drank.
Water is composed of two elements, Hydrogen and Oxygen. 2 Hydrogen + 1 Oxygen = H2O.
Nearly 97% of the world’s water is salty or otherwise undrinkable. Another 2% is locked in ice caps and glaciers. That leaves just 1% for all of humanity’s needs — all its agricultural, residential, manufacturing, community, and personal needs.
Water regulates the Earth’s temperature. It also regulates the temperature of the human body, carries nutrients and oxygen to cells, cushions joints, protects organs and tissues, and removes wastes.
75% of the human brain is water and 75% of a living tree is water.
A person can live about a month without food, but only about a week without water.
Water is part of a deeply interconnected system. What we pour on the ground ends up in our water, and what we spew into the sky ends up in our water.
The average total home water use for each person in the U.S. is about 50 gallons a day.
The average cost for water supplied to a home in the U.S. is about $2.00 for 1,000 gallons, which equals about 5 gallons for a penny.
Water expands by 9% when it freezes. Frozen water (ice) is lighter than water, which is why ice floats in water.

Flash floods resulting from extreme rainfall pose a major risk to people and infrastructure, especially in urban areas. Higher temperatures due to global climate change affect continuous rainfall and short rain showers in somewhat equal measure. However, if both types of precipitation occur at the same time, as is typical for thunderstorm cloud clusters, the amount of precipitation increases more strongly with increasing temperature, as shown in a recent study.

Water is the foundation of life. And still today, all around the world, far too many people spend their entire day searching for it.

In places like sub-Saharan Africa, time lost gathering water and suffering from water-borne diseases is limiting people's true potential, especially women and girls.

Education is lost to sickness. Economic development is lost while people merely try to survive. But it doesn't have to be like this. It's needless suffering.

Our demand for water is constantly increasing. Every year, there are more people in the world. Factories turn out more and more products, and need more and more water. We live in a world of water. But almost all of it—about 97 percent—is in the oceans. This water is too salty to be used for drinking, farming, and manufacturing. Only about 3 percent of the world's water is fresh (unsalty). Most of this water is not easily available to people because it is locked in ice that covers Antarctica, Greenland, and the waters of the north polar region. But there is still enough to meet people's needs.

isn't that a lot??????????????????

Every nine days, more than 8 million people in the city and 11 surrounding municipalities have had their water shut off for 24 hours. Households and businesses were forced to adapt by storing water in advance and cutting daily consumption.

Bogotá’s mayor, Carlos Fernando Galan, announced on Friday that the rationing will end on Saturday, declaring that the crisis has been resolved thanks to improved rainfall, effective conservation efforts and the expansion of a treatment plant that eased demand on the reservoirs, which had fallen to record lows last year.

1.1 billion people worldwide lack access to water, and a total of 2.7 billion find water scarce for at least one month of the year. Inadequate sanitation is also a problem for 2.4 billion people—they are exposed to diseases, such as cholera and typhoid fever, and other water-borne illnesses. Two million people, mostly children, die each year from diarrheal diseases alone. Rivers, lakes and aquifers are drying up or becoming too polluted to use. More than half the world’s wetlands have disappeared. Agriculture consumes more water than any other source and wastes much of that through inefficiencies. Climate change is altering patterns of weather and water around the world, causing shortages and droughts in some areas and floods in others. About half of the world’s wetlands have been destroyed since 1900. Some of the most productive habitats on the planet, wetlands support high concentrations of animals—including mammals, birds, fish and invertebrates—and serve as nurseries for many of these species. Wetlands also support the cultivation of rice, a staple in the diet of half the world’s population. And they provide a range of ecosystem services that benefit humanity, including water filtration, storm protection, flood control and recreation.

Damaged Ecosystems

When water becomes scarce, natural landscapes often lose out. The Aral Sea in central Asia was once the world’s fourth largest freshwater lake. But in only three decades, the sea has lost an area the size of Lake Michigan. It is now as salty as an ocean due to the excessive pollution and the diversion of water for irrigation and power generation. As the sea has retracted, it has left polluted land. This ecological catastrophe has created food shortages and resulted in a rise in infant mortality and a decrease in life expectancy for the nearby population.
