2 . What do you think of when you hear the word “drought”: Do you think of “dry” “hot” “dusty” “cracked (开裂的) earth” or even “no water”? If so you’re on the right track!
When some places are in drought, they may be dry, hot and dusty. Cracks may appear in the soil, and rivers, lakes, streams and other sources of water may go dry. Other places in drought get some rain, but not as much as they usually receive during that season. Drought means that a place has less rain or snow than normal over a few months or even longer.
Drought has many causes. It can be caused by not receiving rain or snow over a period of time. We learned in the discussions above about the water cycle and weather. The changes in the wind patterns that move clouds and moisture through the atmosphere can cause a place not to receive its normal amount of rain or snow over a long period of time.
If you live in a place where most of the water you use comes from a river, a drought in your area can be caused by places upstream from you not receiving enough moisture. There would be less water in the river for you and other people who live along the river to use.
People can also play a big role in a drought. If we use too much water during times of normal rainfall, we might not have enough water when a drought happens.
