Read the passage and answer the questions that follow :
Trees prevent the surface soil of the earth from being washed
away by shower. Our earth has a covering of fine soil on
the surface, and under the soil lie rocks of various kinds.
The surface soil supports the life plants, which in turn, supply
the food that animals need. Nature takes millions of years
to form soil an inch thick. But a single heavy shower
sometimes, washes off a good part of the surface soil on a
bare hillside. This will not happen in places where there are
plenty of trees. Since the trees stop the fair flow of water
and their roots hold the soil together, they prevent the soil
from being washed away. The soil in forests absorbs water
very easily and in this way trees also help to prevent sudden
floods.​
