Book 30, Question 89
What happens when a region goes a long time without rain?
A long dry period is called a drought.
Streams shrink, ponds dry up, lakes drop, and plants wilt. Towns may ask people to water lawns less or wash cars less. Farmers worry about crops. When rain returns, the land slowly recovers. Scientists watch rainfall, snow, and water levels to warn communities in time. Saving water before a drought helps everyone.
