Answer 1

Droughts happen when there is not enough rain for a long period of time. It's not like a dry spell - there is so little precipitation (rain, snow, sleet or any kind of moisture) that a whole region starts to dry out. Sometimes a drought takes decades to develop fully and they are very difficult to predict.

When there is no rain for one or two years then chances of drought occurs. Because usually, due to evaporation and transpiration water is lost by soil, pods, lakes etc. But if no rainfall will occur for a longer period of time, then the water level in various ponds, river, lakes and wells decreases. This leads to the condition of drought.
