A drought is considered a period of abnormally dry weather that causes hydrological imbalance. There are three general types of a drought.
1. A meteorological drought is any lack of rainfall over a long period of time.
2. A hydrological drought occurs when there are critically low ground water tables, and reduced river, and stream flow.
3. An agricultural drought is when there is extreme heat. This is probably one of the most common droughts. This drought occurs when there is a lack of rainfall and moisture.
When droughts happened in foreign countries many years ago, people would collect the moss off of trees and make it into bread and put it into their soup.
Droughts are a major natural disasters in many parts of the worlds. Areas where there is a lot of precipitation are most prone to droughts. They can cause hundreds of millions of dollars in damage. They can damage the environment by soil erosion, vegetation damage, and loss of wildlife. After a drought many people die of malnutrition and starvation.
Droughts may take many months to develop, and people do not usually realize that a drought is happening until many weeks into the droughts.
After a while, a drought may lead to a forest fire.
1988 was a very bad year of droughts.
