Whrite a short note on the topic drought disastertopic-drought disaster
Answers
Drought is a continuous period of dry weather, when an area gets less than its normal amount of rain, over months or even years. Crops and other plants need water to grow, and animals need it to live. Droughts can become dangerous to people and other land animals; causing famine and even creating deserts.
A drought is a natural event, caused by other weather events like El Niño and high-pressure systems. Drought can also be triggered by deforestation (people cutting down forests), by global warming, and by diverting rivers or emptying lakes.
Drought is a natural disaster which usually takes place slowly. It is often difficult to decide when a drought started and sometimes when it ends too. Its effects often build up slowly over a long period of time and may last from months to years after rain resumes.
Many people die every year in famines due to drought in subsistence farming areas. Conflicts can result from drought conditions.

The joint family is an extension of the nuclear family (parents and dependent children), and it typically grows when children of one sex do not leave their parents' home at marriage but bring their spouses to live with themdrought is caused by drier than normal conditions that can eventually lead to water supply problems. Really hot temperatures can make a drought worse by causing moisture to evaporate from the soil. Just because a region is hot and dry doesn't necessarily mean it is going through a drought. Droughts only occur when an area is abnormally dry. Here's why:
Rain and snow don’t fall evenly across Earth. Some regions are routinely wet and others are routinely dry. From season to season — and from year to year — the amount of rain or snow in a location can vary.
However, over a period of many years, the average amount of precipitation in a region is fairly consistent. For example, in the deserts of the American Southwest, the average precipitation is less than 3 inches per year. But, the average yearly precipitation in Atlanta is about 50 inches.
When a particular area gets less rain than usual, the soil gets much less moisture, too. The soil starts drying out and plants die. When this pattern continues for several weeks, months or years, the flow of streams and rivers decreases and water levels in lakes, reservoirs and wells fall. Eventually, the unusual dry weather causes water supply issues, and the dry period becomes a drought
