A. Deforestation

EXTINCTION
is the displacement of the upper layer of
soil, it is one form of soil degradation.
This natural process is caused by the
dynamic activity of erosive agents, that
is, water, ice, snow, air, plants, animals,
and humans.

5. Variety of life in an area.
6. It is the displacement of the upper layer of soil, it is one form of soil degradation.
7. Removing or clearing of a forest that includes cutting of all trees.
