Detailed explanation-1: -A drought is an extended period of unusually dry weather with no rain or other precipitation.

Detailed explanation-2: -A drought is a long period of time during which no rain falls.

Detailed explanation-3: -If a weather pattern that results in a precipitation deficit lasts for a few weeks or months, it is considered short-term drought. If the pattern and precipitation deficits last for more than six months, it is typically considered long-term drought.

Detailed explanation-4: -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.

Detailed explanation-5: -Drought is a long period without rains leading to a severe shortage of water in the region. The soil continues to lose water by evaporation and transpiration. If, however, it does rain at all or the rainfall is very low for a long period, the loss of water from the soil is not made up and hence the soil becomes dry.
