Question

Excessive withdrawal of groundwater for agricultural use rarely causes land subsidence, unlike excessive withdrawal for drinking water, which does cause subsidence.
a. True

b. False

Answer 1

The correct answer is False

Explanation:

The term "subsidence" describes a phenomenon in which the ground's surface sinks or has a downward movement. This can be naturally caused by certain processes such as natural compaction or natural changes in the soil. However, nowadays most cases of subsidence are the result of human actives and especially due to the withdrawal of materials that are underground such as petroleum or groundwater.

In the case of groundwater, which refers to the extraction of water that is beneath the surface of soil, this is used for multiple purposes such as irrigating crops, getting drinking water and for industry and in all these cases it can lead to subsidence depending on the conditions of the soil and the amount of water extracted. This implies both types of withdrawals of groundwater cause subsidence and therefore it is false withdrawal of groundwater for agriculture does not cause land subsidence but withdrawal for water does.
