How does erosion affect land over time?

Over time, even the largest mountains are worn down by weathering and erosion. Weathering is "rock decay," which occurs through physical, chemical and biological processes. Once the minerals have been weathered and broken down, they are prone to being transported (eroded) by wind, water and ice Topsoil is formed over hundreds to thousands of years, through complex interactions among the bacteria, fungi, worms and insects, that live among the roots of plants and help to break down organic matter.

When topsoil is washed away by erosion, the land becomes much less fertile, and can support fewer plant and animal species Soil and sediment that is washed into natural water bodies degrades water quality and fish habitat in a number of ways.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
