I notice that in 1984 it’s really green but through 2015 the land starts to turn brown.

And it get more cloudy the more you go up on the timeline.

finally in 2020 you can see that the terrain  is rough and that there are small  there are little mountains.

You can see a lot of changes through these times, and it’s really interesting to see the time lapse over a lot of years.

I noticed that the volcano (Eyjafjallajökull) exploded in between 2009 and 2010. Also I that there was a big change in the land around the volcano, before the volcano exploded the ground was beautiful and after it exploded it was all brown.

Also I noticed a lot of smoke and destruction even in places more than 6 kilometers far of the volcano and I noticed that the volcano also started growing back in 2013.

Bushfires
I noticed that year after year the fire kept spreading and spreading. Some parts of the forests were completely burn down as you can see in the time lapse.

Weather conditions in Australia like strong winds and high temperatures and low humidity create conditions for dangerous bushfires.

The biggest bushfires in South Australia seems to have happened during  2005, 2007, 2015 and 2019-20.

These bushfires claimed 1,000 of acres of forests.

The ice is melting from the south because you can see the south there is not a lot of ice so that mean the south is warm maybe because the temperature if getting warmer or global warming.

American shorthair cats,

One interesting detail about American shorthairs is that their eyes come in differently colors like gold, copper, green or blue.

Another interesting detail is that American shorthairs are very quiet, they even have their own silent “meow”.

Another interesting detail is that American shorthairs sometimes communicate by nibbling their owners toes.

One interesting thing I learned is that American shorthair kittens can stand up after three months.

Erosion is a process where natural forces like water, wind, ice, and gravity wear away rocks and soil. It is a geological process, and part of the rock cycle. Erosion occurs at the Earth's surface, and has no effect on the Earth's mantle and core.

Most of the energy that makes erosion happen is provided by the Sun. The Sun's energy causes the movement of water and ice in the water cycle and the movement of air to create wind.

Erosion can cause problems that affect humans. Soil erosion, for example, can create problems for farmers. Soil erosion can remove soil, leaving a thin layer or rocky soil behind. Erosion can also cause problems for humans by removing rocks or soil that support buildings.

Erosion by water

Temperature changes cause pieces of rock to flake away from the surface. Also, the acid in rainwater dissolves rocks containing calcium carbonate. These processes are called weathering.

Water erosion happens when water moves the pieces of rock or soil downhill. Waves also carry away small pieces of material. A wave can wash up onto the surface of rock or soil and then carry away pieces of material as it flows back into the ocean or lake.

The size of earth materials that can be moved by water depends on how fast the water is moving. A fast-flowing stream can carry large rocks while a slow moving stream might only be able to carry very small things like clay. Canyons, like the Grand Canyon, are among the most obvious features made by erosion. Where a river meets the sea, it drops the solids, sometimes making a river delta.

Tropical rivers

Large tropical rivers like the Paraná, Indus, Brahmaputra, Ganges, Zambezi, Mississippi and the Amazon carry huge amounts of sediment down to the sea. The Nile, perhaps the world's longest river, carries much less sediment than the others because, part of the way, it runs through less fertile regions than the other great rivers.

The Amazon has by far the largest waterflow, with an average discharge greater than the next seven largest rivers combined. It has the largest drainage basin in the world, about 7,050,000 square kilometres (2,720,000 sq mi). The Amazon accounts for about one-fifth of the world's total river flow.

The sediment discharged by the gigantic mouth of the Amazon stains the sea brown for hundreds of miles out to sea.

Erosion by ice

Ice erosion happens when a glacier moves downhill. As the ice of the glacier moves downhill, it pushes and pulls earth materials along with it. Glaciers can move very large rocks. Ice erosion can happen in another way. Cold weather causes water inside tiny cracks in rocks to freeze. As it freezes, the ice gets bigger, and pushes hard against the rock. This can break the rock.

Erosion by wind

Wind erosion occurs when wind moves pieces of earth materials. Wind erosion is one of the weakest kinds of erosion. Small pieces of earth material can be rolled along the ground surface by wind. Very small pieces can be picked up and carried by the wind. Sometimes, wind can carry small pieces of earth materials over large distances. Some sediment from the Sahara Desert is carried across the Atlantic Ocean by wind.

One of the most famous examples of wind erosion occurred in the Dust Bowl, when wind erosion severely damaged farming communities.

Erosion by gravity

Gravity erosion is the simplest kind of erosion. Gravity simply pulls loose earth materials downhill. Landslides are dramatic examples of gravity erosion.

Erosion and tectonics

Tectonic effects on erosion has long been recognized. For example, rivers form as a result of tectonic uplift (as Himalayas and Tibetan Plateau). All of the Earth's mountain ranges were created by the upward movement of the land by changes beneath the Earth's surface. When the ground rises the whole weather system can also be changed including local sea levels, wind strength and direction, rainfall and more.

The Earth's landscape is a product of two factors. Tectonics builds up height by surface and rock uplift, and climate controls the erosion. Erosion wears away upland areas over time. The interaction of these processes can form, modify, or destroy features of the Earth's surface.

Cause ➡️Soil is the earth’s fragile skin that anchors all life on Earth. It is comprised of countless species that create a dynamic and complex ecosystem and is among the most precious resources to humans. Increased demand for agriculture commodities generates incentives to convert forests and grasslands to farm fields and pastures. The transition to agriculture from natural vegetation often cannot hold onto the soil and many of these plants, such as coffee, cotton, palm oil, soybean and wheat, can actually increase soil erosion beyond the soil’s ability to maintain itself.

Half of the topsoil on the planet has been lost in the last 150 years. In addition to erosion, soil quality is affected by other aspects of agriculture. These impacts include compaction, loss of soil structure, nutrient degradation, and soil salinity. These are very real and at times severe issues.

Effect ➡️The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding. Sustainable land use can help to reduce the impacts of agriculture and livestock, preventing soil degradation and erosion and the loss of valuable land to desertification.

The health of soil is a primary concern to farmers and the global community whose livelihoods depend on well managed agriculture that starts with the dirt beneath our feet. While there are many challenges to maintaining healthy soil, there are also solutions and a dedicated group of people, including WWF, who work to innovate and maintain the fragile skin from which biodiversity springs.
