Question

what are the main cause of drought and floods

Answer 1

It can be caused by not receiving rain or snow over a period of time. We learned in the discussions about the water cycle and weather that changes in the wind patterns that move clouds and moisture through the atmosphere can cause a place to not receive its normal amount of rain or snow over a long period of time.


However, floods are not always caused by heavy rainfall. They can result from other phenomena, particularly in coastal areas where inundation can be caused by a storm surge associated with a tropical cyclone, a tsunami or a high tide coinciding with higher than normal river levels.

⚫ Deforestation plays many roles in the flooding equation because trees prevent sediment runoffs and forests hold more water than farms or grasslands. The flood equation is simple. If a river cannot handle the load of water it is required to carry, it will rise above its banks. This is when floods occur.

⚫Eventually, deforestation and soil erosion would dry up the place where it happens, since water isn't absorbed. This will disrupt the natural water cycle, and causes drought .
