What happens:
* Wearing away: The forces break down the material into smaller pieces. This can happen through:
* Abrasion: Particles rub against each other, like sandpaper.
* Corrosion: Chemical reactions dissolve or break down the material.
* Transporting: The eroded material is carried away from its original location by the force.
Examples of Erosion:
* Water Erosion: Rivers carving canyons, rain washing away topsoil, ocean waves eroding coastlines.
* Wind Erosion: Dust storms carrying soil, sand dunes shifting in the desert.
* Ice Erosion: Glaciers carving valleys, frost wedging breaking rocks.
Impacts of Erosion:
* Loss of Soil: Reduces soil fertility and can lead to desertification.
* Damage to Infrastructure: Can erode roads, bridges, and buildings.
* Pollution: Eroded sediment can pollute waterways and harm aquatic life.
Erosion is a natural process, but human activities can accelerate it. This can be caused by deforestation, urbanization, and agriculture.
