What is a drought?
A drought is when there is a lack of precipitation over an extended period of time, usually a season or more, resulting in a water shortage for some activity, group, or environmental sector.
It is a long period of dry weather or extended periods of time with less than average rainfall.

CAUSES
EFFECTS
Droughts can be caused two ways: naturally and because of human impact. A shortage of rain or snow, lack of moisture up stream, high pressure systems, and global warming patterns can all naturally cause a drought. If man places a greater demand on the water system than there is supply, this can also lead to a drought.

Droughts in history....
What: The Dust Bowl
When: 1930's (lasted a decade)
Where: The great plains of the United States (Kansas, Nebraska, Iowa, etc)
Why: The combination of lack of rain, high temperatures, and strong winds affected at least 50 million acres of land. Massive clouds of dust and sand formed as unusually strong winds lifted the dry soil into the air. These clouds could block out the sun for days, giving the period the name “dust bowl.”
