Tsunamis

# data[].attributes.attachment_link.readable_text
They can speed across the ocean as fast as a jet plane, swallow up islands and wipe out villages.

But what causes tsuamis...? Join National Geographic Kids and dive into our tsunami facts to find out!

What causes a tsunami?

Meaning " great harbour wave" in Japanese, tsunamis are sometimes called "tidal waves" but their strength has nothing to do with the tides. About four out of five tsunamis happen within the Ring Of Fire, a zone in the Pacific Ocean where earthquakes and volcanic eruptions frequently take place.

Giant slabs of the Earth's crust, called tectonic plates, grind together. Sometimes, though, the plates get stuck, the pressure builds up and they suddenly slam into a new position. This causes an earthquake. If an earthquake lifts or drops part of the ocean floor, the water above rises and starts spreading across the ocean, causing a tsunami. Underwater landslides or volcanic eruptions can also displace water (cause water to spread across the ocean) and may lead to a tsunami.

How big is a tsunami?

Out in the open ocean, tsunami waves are only about one-metre high because the water is deep. However, as the water becomes shallow, the waves slow down and begin to grow. They can rise 35m or higher - that's the same as a 10-floor block of flats! However, the scariest thing about a tsunami is its wavelength, as this determines how far inland it can travel. Whereas a large wave caused by a storm might have a wavelength of up to 150m, a tsunami could reach up to a fearsome 1,000km!

How fast is a tsunami?

A normal wind wave travels at about 90kmh, but a tsunami can race across the ocean at an incredible 970kmh! Sometimes, before a tsunami hits, there is a huge vacuum effect, sucking water from harbours and beaches. People can see the ocean floor littered with flopping fish and other sea animals. Then a wave blasts onto the shore minutes later, then another and another for two hours or more. There may also be up to one hour between each wave.

Can you predict when a tsunami is coming?

To save lives, scientists established the Pacific Tsunami Warning System, based in Hawaii, in the USA. Its network of detectors can track quakes that may cause a tsunami. These waves can race from one side of the Pacific Ocean to the other in less than a day, so people need to be warned in time to head for higher ground!

What do you think of these tsunami facts? Let us know by leaving a comment, below!

Is it where you live? When it starts to get colder outside, you may hear weather forecasters talk about a cold moving into your area. Have you ever WONDERed what they're talking about?

In weather terms, a is the between air masses of different temperatures. A cold is the leading edge of a mass of cooler air that is pushing warmer air ahead of it out of the way.

As a cold moves into an area, it displaces warmer air at level. Colder air is than warm air, so it pushes the warm air higher into the atmosphere . Temperature changes along the of the cold/warm air can be in excess of 50° F (10° C).

As the warm air rises, it causes an area of low pressure along the cold . The warm air cools as it rises and begins to condense.

If enough is present, a line of thunderstorms and rain can form along the edge of the cold . If the cold is , thunderstorms are more likely. Stable systems often just bring steady rains. Very cold fronts can hail storms and even tornadoes.

Cold fronts usually move from northwest to southeast. They tend to be strongest in the spring and the fall and weakest in the summer. In addition to rain and thunderstorms, they also bring , shifting winds.

Winter cold fronts might not any precipitation at all if there's insufficient in the air. If there's in the air, though, a cold can bring significant snowfall.

Cold fronts move much faster than warm fronts and can cause sharper changes in the weather. As a cold is passing through, you will notice temperatures drop quickly and then as it passes.

If you're watching the weather forecast on your local news, a cold will be marked by a solid blue line. The blue line marking the cold might also include triangles pointing in the direction the cold is moving.

Do you enjoy a good thunderstorm? While rain can end baseball games and outside events, it brings needed nourishment to plants everywhere. It can also be fun to cuddle up inside under a blanket to watch a movie or take a nap while the thunder booms and the rain beats a on the .

Sometimes, though, storms take a turn for the worse and into dangerous beasts, such as tornadoes and hurricanes. For those who have ever experienced the deadly power of one of these storms, Mother Nature can seem quite . Every year places all over Earth fall to the weather that can exist on this planet we call home.

But what about the other planets in the solar system? Could we escape Earth's deadly storms and take on another planet? Or are there even worse fates awaiting future interstellar travelers?

While human beings will always to explore the rest of the solar system, the weather on other planets can present a significant to future travel plans. If you think the weather on Earth can be bad at times, just wait until you learn what the weather on other planets has in store for you.

For example, many people hope that one day we can send a manned mission to Mars. Would you want to go? Maybe not when you see the weather forecast! Mars doesn't have much of an atmosphere. It's mostly a dry, rocky desert. What winds there are tend to kick up vicious dust storms that can the entire planet and last for weeks.

The huge gas giants, Jupiter and Saturn, have even more awe-inspiring storms. The first astronomers dating back to the time of Galileo noticed a large red spot on Jupiter's surface. That spot, now known as the Great Red Spot, is actually a hurricane-like storm twice as large as Earth...and it's been raging for hundreds of years!

Saturn has a spot of its own now, too. Called the Great White Spot, it's a thunderstorm that began within the last couple of years and is still going strong. Scientists estimate the storm is over 6,200 miles wide! By way of comparison , the largest hurricanes on Earth might approach 600 miles in width.

Instead of heading out to Jupiter and Saturn, what if we ventured closer to the Sun? Venus is similar to Earth in shape and size. Unfortunately, that's where the similarities end. Its dense atmosphere features blazing temperatures of nearly 900º F year-round. That dense atmosphere also happens to be made of carbon dioxide clouds, which rain down sulfuric acid.

Another celestial body similar to Earth in terms of cloud cover and terrain is Titan, Saturn's largest moon. Unlike Earth, though, Titan's clouds are made of rather than water. Similar to Earth's water cycle, Titan features rains as part of a regular cycle.

also features prominently in the weather on Neptune. Neptune is so far away from the Sun, though, that the there is frozen in clouds that get blown around the planet by winds up to 1,200 miles per hour. That's nearly five times the fastest winds to ever blast Earth during a hurricane.

Today's Wonder of the Day was inspired by Madelynn. Madelynn Wonders, " what causes droughts " Thanks for WONDERing with us, Madelynn!

Do you like to keep an eye on the weather? Rather than watching the weather report on television, most kids simply head outside and check the skies. Is it sunny or cloudy? Just look up!

Of course, looking up only tells you what the weather's like at that particular . It doesn't tell you much about what the weather will be like in a few hours or a few days. To get an of what the weather will be like over the next week, you'll need help from a meteorologist .

People keep a close eye on the weather for many different reasons. In addition to knowing how to dress appropriately , many people want to know if plans might be interrupted by rain. Others, such as farmers, might be hoping for rain and to know when it'll arrive.

Most people tend to prefer sunshine over rain. In fact, some people wish that it would never rain. If they got their wish, though, they would definitely it, as the world isn't a very place to live in without rain. Just ask anyone who has experienced a severe drought.

In meteorological terms, a drought is a period of time with lower-than-normal precipitation. How long? That varies depending upon what the is normally like. It also depends upon your perspective . A few weeks or even months with little rain is normal in desert areas. If you're a farmer who just planted , though, a few weeks without rain can be disastrous .

Unlike hurricanes and tornadoes, whose devastation is felt immediately, the effects of drought can take a while to appear. That doesn't mean those effects are any less powerful, though. Sustained drought can have a worldwide impact on millions of people.

Drought can be caused by many factors. The primary cause is a sustained lack of precipitation. As with any weather-related phenomenon, there can be many factors that affect the amount of rain or an area gets.

An area with normal rainfall might still experience drought, though. How is that possible? Some areas get most of the water they use from rivers. If areas upstream do not get their normal amount of precipitation, then river levels can drop, resulting in drought conditions far downstream.

People can also play a role in causing droughts. Using too much water can strain local water supplies. Poor farming practices can also make matters worse. For example, humans were definitely a contributing factor to the severe drought conditions known as The Dust Bowl in the Midwest United States during the 1930s.

When a drought takes hold, its impact can be widespread and severe. Lands dry out. and food supplies can dwindle. Streams and rivers dry up. The level of water in lakes, reservoirs, and wells decreases. Just think of all the ways on which you rely upon water. During a drought, all those things are impacted.

So how does a drought end? One good rainfall usually isn't enough. Just like a drought often develops slowly, the end of a drought often takes a long time, too. An extended period of time with above-average precipitation is often required.

The type of precipitation can also be important. Light rains and thunderstorms usually don't do much good. Light rains don't bring enough water, whereas thunderstorms can bring too much water too soon. Extended, soaking rains do the most good to alleviate drought.

This of converting water and carbon dioxide into and is called photosynthesis . A called chlorophyll helps the of photosynthesis occur. Chlorophyll is also what gives plants their green color.

As summer ends and begins, the days get shorter and shorter. With fewer daylight hours, leaves are not able to make as much chlorophyll as they can during the long daylight hours of spring and summer. As the chlorophyll fades, we are able to see other colors, such as orange and yellow, .

Many people mistakenly believe that weather makes leaves change color. While this is not true, weather can affect how vibrantly the colors appear.

If the weather is too hot or cold, the leaves will not be as bright as they begin to change. The best weather for foliage is sunny, warm days and cool nights.

Water also plays an important in colors. If a tree doesn't receive water, the leaves will die faster and fall to the ground. If there is too much rain, the tree won't receive sunlight, and the leaves will not be brightly colored.

You may be surprised to learn that each has small amounts of other colors in it year-round, even if we can't see them. During the spring and summer, chlorophyll overpowers the other colors, and all we see is green. With less chlorophyll to give the its green color, we begin to see the other colors, such as orange, yellow, and red, which have been there all along.

However, plays an important role in our world. It replenishes the Earth with water and helps our plants grow. Without regular rainfall, our world would be a dry, dusty place that wouldn't be any fun at all.

If you see clouds roll in on a sunny day, it could mean that is on the way. Have you ever stared at those clouds and wondered whether they hold and, if so, how much?

As it turns out, that question isn't easy to answer. Why? Clouds aren't like buckets, so they don't really "hold" water like a bucket would.

Whether you realize it or not, the air around you is filled with water. Water comes in three forms: liquid (that you drink), solid (ice) and gas (water in the air). The amount of water inside a is no different than the amount of water in the air around it.

In the air around a , water is a gas in the form of water . Inside the , cooler temperatures have transformed water into a liquid. This liquid is in the form of millions, billions or even trillions of tiny water droplets called droplets. Scientists call this process condensation .

When water in the air condenses into tiny droplets, those droplets become visible. What we see is a . Whether that liquid water will fall to the ground as depends on many factors.

droplets are very tiny and weigh very little. In a , they float with the wind or simply hang in the air. In addition, updrafts (winds that blow upward from the surface of the Earth) also help keep droplets suspended within a .

To fall to Earth, droplets have to become heavier. If they combine with other droplets or if more liquid water continues to condense out of the air, they eventually become heavy enough to form drops that fall to Earth as . The scientific word for rainfall is precipitation .

Once droplets grow into drops and fall to Earth as , it will continue to as long as conditions in the atmosphere keep causing water to condense into liquid water and grow into drops heavy enough to fall as .

So how much can a produce? This is perhaps a better question than how much a can hold. Scientists estimate that one inch of falling over an area of one square mile is equal to 17.4 million gallons of water. That much water would weigh 143 million pounds!

Many factors, such as elevation, ocean currents, distance from the sea, and prevailing winds, can affect the of an area. One of the most important things that influences , though, is . The of an area indicates how far it is - north or south - of the equator.

affects because it is related to the length and intensity of sunlight an area receives. As Earth orbits the sun, sometimes the Northern Hemisphere is tipped toward the Sun, while at other times the Southern Hemisphere is tipped toward the Sun.

When a is closer to the Sun, its days are longer, and the Sun's rays are stronger and more direct. When our hemisphere is tipped toward the Sun, we experience warmer and longer days. This is our summer. When we tip away from the Sun, the days are shorter and colder. This is winter.

But none of this explains why Detroit and Miami would have such different on the same day in the same month, does it? Actually... it does!

Miami is much closer to the equator than Detroit. This means the tipping of the hemispheres has less extreme effects on Miami than Detroit. Because Miami is closer to the equator, it receives a lot of sunlight and warmth all year long and thus maintains a warm .

You check the clock and realize you're running late. The school bus is going to arrive any minute now. You grab your backpack and head for the door, but you're stopped by a parent's voice reminding you to grab your coat and an umbrella.

What's the deal? You look out the door, and it doesn't look cold or rainy. Before you can even protest, you're told that the temperature is going to drop when it begins to rain later this afternoon. Can your parents see into the ? Do they have a crystal ball? Not likely! They probably just checked the weather forecast.

Weather forecasts help us prepare for the , whether it's a few hours from now or the rest of the week. Not only do they warn us of potentially -dangerous weather headed our way, they also give us an of what to expect in terms of temperature and chance of precipitation , so we can dress and ourselves appropriately.

The people who study the weather and put together forecasts are scientists known as meteorologists. Have you ever seen a forecast that called for lots of snow? You might have gotten excited, anticipating a snow day and the chance to do some sledding. Unfortunately, you woke up to clear skies, no snow, and a full day of school ahead. What happened? How could the weather forecast have been so wrong?

Weather forecasting is not a perfect science. Forecasts are a prediction based upon an educated . Since there are a wide variety of factors that go into a forecast, it's possible for meteorologists to wrong from time to time. Fortunately, modern technology has allowed forecasters to become much more over the last decade.

Today, meteorologists use complicated mathematical equations to help predict the weather as part of a process known as numerical forecasting. Numerical forecasting requires powerful supercomputers and tons of observational from land, sea, and air weather stations around the world.

Where does all this come from? Sometimes it comes from regular people like you! Many people create their own backyard weather stations with thermometers to measure temperature and rain gauges to measure precipitation . They can report their observations to meteorologists to help improve forecasts.

Technologically-advanced weather stations are established by meteorologists all over the world. They collect and share to help improve forecasts. Some of the tools they use include barometers that measure air pressure, anemometers that measure wind speed, Doppler stations to monitor the movement of weather fronts, and psychrometers to measure relative humidity.

To get from the seas and the upper atmosphere, -collection tools and instruments may be attached to ships, airplanes, and even buoys in the middle of the ocean. Weather balloons and weather satellites also provide observational that can be used on a global scale to spot weather trends for large areas.

All these different types of tools around the world produce millions of pieces of weather-related observational every single day. Supercomputers, such as those at the National Centers for Environmental Prediction in Camp Springs, Maryland, process that to produce forecasts based upon complicated mathematical models. Current is compared to similar patterns that have occurred in the past to determine what will likely happen in the .
