Question

Which amongst the following options will lead to drought?

• A. Water conservation
• B. Excessive use of groundwater
• C. Soil erosion
• D. Heavy rainfall

Answer 1

The correct option is B Excessive use of groundwater

$\bullet$ Drought is the deficiency of rainfall, in an area, over a prolonged time period. Places affected by drought will have severe water shortage, which adversely affects the vegetation, animals and people of that area.

$\bullet$ Excessive pumping of groundwater can decrease the groundwater level, which leads to water scarcity and ultimately results in drought.

$\bullet$ Soil erosion cannot cause drought. However, drought can lead to soil erosion. This occurs when the dried up soil gets carried away by the wind.

$\bullet$ However, water conservation and heavy rainfall are not responsible for causing drought. Water conservation is important because fresh water sources are limited.
