USA HISTORY

Detailed explanation-1: -A drought is an extended period of unusually dry weather with no rain or other precipitation. Entire ecosystems, such as this pine forest near Los Alamos, New Mexico, can be devastated by droughts.

Detailed explanation-2: -To a meteorologist, a drought is a prolonged period when precipitation is less than normal. To a water manager, a drought is a deficiency in water supply that affects water availability and water quality. To a hydrologist, a drought is an extended period of decreased precipitation and streamflow.

Detailed explanation-3: -A drought is defined as “a period of abnormally dry weather sufficiently prolonged for the lack of water to cause serious hydrologic imbalance in the affected area.”-Glossary of Meteorology (1959).

Detailed explanation-4: -Drought is a prolonged dry period in the natural climate cycle that can occur anywhere in the world. It is a slow-onset disaster characterized by the lack of precipitation, resulting in a water shortage. Drought can have a serious impact on health, agriculture, economies, energy and the environment.

Detailed explanation-5: -If there is no rain for a long period or for many years, then there is scarcity of water in that region. This leads to drought. The lack of adequate precipitation, either rain or snow, can cause reduced soil moisture or groundwater, diminished stream flow, crop damage, and a general water shortage.
