A drought is when an area lacks water for a long period of time. This is usually because it doesn’t rain enough. There is little water in the soil and the air is not humid enough either.
This is initially bad for the plants in the area. They hardly grow or even dry up, and they don’t spread. If there are few plants, it is bad for animals that live on plants. In the end, this is also a problem for the people who live in the area. You then not only have too little drinking water but also little to eat.
In some areas droughts are normal, that’s part of the climate there. For example, a drought occurs in a certain season. Elsewhere, droughts are a major exception.
