Amazingly small animals, insects, and worms cause erosion as they break up the soil. This makes it easier for the wind and water to whip it up and carry it away. Amazingly gravity is another force of erosion. The force of gravity pulls rocks and other particles off the side of a mountain and this causes erosion.

What are negative effects of erosion?

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.
