If the surface soil is saturated and precipitation increases, there will be

a. a decrease in the surface elevation of the lake

b. a decrease in the amount of groundwater

c. an increase in the rate of capillarity

d. an increase in the amount of runoff

The correct answer is D. An increase in the amount of runoff

Explanation:

Surface soil is considered to be "saturated" if soil cannot absorb more water as all pores in it are already filled. This can occur when there has been a lot of precipitation, or the retention of soil is low. Additionally, when soil is saturated and it is in contact with more water (for example, if precipitation increases) the water will not be absorbed by the soil but will flow to other areas, which is known as runoff. Thus, if the surface soil is saturated and there is precipitation, there will be an increase in the amount of runoff.
