What is erosion?
erosion concerns the gradual transmission of materials around the Earth's surface. Because it always travels down the slope, it can lead to wear of natural elements. Erosion is one of the most important processes that shape the Earth's surface. In fact, if the country stagnated, these forces would eventually smooth the entire surface of the Earth and create a global ocean. However, it is also a natural process and important because it moves the nutrients around and forms hospitable places on Earth for plants and animals. The process is paired with deposition, accumulation of rocks and sediment in new configurations.
In natural erosion, several different processes are involved. The weather, the right and dissolution are three more common, although it can also be caused by abrasion and corrosion. Wind, water, gravity and LED move solids on the Earth's surface in constantly changing samples. Some of the most dramatic examples were caused by ice because it moves somewhat like liquid but also expands and contrasts. For example, massive fjords Norway represent a form of glacial erosion.
Many people have noticed that water is also a strong erosive force, especially in times of heavy rain, when the rivers can brown with mud and sediments. The erosion on the rivers was significantly accelerated by human activity that releases the topsoil around the rivers, so it is vulnerable to escape. The nutrient topsoil will end up on the sea, where they eventually settle over the continental shelf and a continental rise to feed various marine Creatures.
wind and gravity can also be impressive, especially in combination with water. As seen during the dust bowl at the age of 30, the wind is perfectly able to transport a large amount of material; Many world sand dunes were created by wind transport. Gravity is also constantly at work, pulls solids and slowly regrops the environment. Rock and Mudslides are excellent examples caused by gravity.
When the soil is eroded at a slow and natural pace, it can be a good thing. The displaced reform of solids in new areas, as the landscape gradually changes and for the new flora and fauna there is a fresh habitat. However, if erosion is extreme, it can be destructive. People are often responsible for extreme cases that can take away most of the topsoil and leave a layer of unusable dirt and rocks behind. Erosion caused by man can also lead to large reefs and drains that disrupt the landscape.
