Topsoil is a fertile combination of minerals and organosubstrate (microorganisms like bacteria and fungi), which plants need to survive and grow. If it is removed (eroded) by water or wind, the remaining sand or rock will be much less fertile and will hamper plant growth. This can turn valuable agricultural land into deserts.
The dirt or topsoil carried by running water is called sediment.
Above the topsoil is the subsoil, which consists of a mixture of clay, minerals, and organic matter. This layer forms as water carries minerals and nutrients down from the topsoil, depositing them in the subsoil layer. This process usually takes hundreds to thousands of years.
Overgrazing can lead to the removal of vegetation cover, causing soil erosion as the topsoil becomes more exposed to wind and water. This can result in a loss of soil fertility, decreased water retention capacity, and increased susceptibility to desertification.
The process is called leaching, where water transports nutrients and compounds from the topsoil to deeper layers, affecting the soil's composition and fertility.
Sediment. Sediment carried by running water can include a variety of particles such as silt, clay, sand, and gravel. This process can lead to erosion and sediment deposition in different locations.

Erosion causes the loss of topsoil. Topsoil from thousand of acres of farmland lost to water and wind erosion each yaer in the united states alone.

It tears earth from the ground and carries it which ever way water flows
When floating seeds are thrown in the running water. These seeds are carried to new locations.
The process is called leaching, where water carries dissolved materials downward through the soil profile. This can lead to nutrients being lost from the topsoil and potentially causing groundwater contamination.
