What r the causes of droughts ?
The cause of all droughts is not enough rainfall. During a drought, the land can become starved of nourishment. The earth is parched and even if some rain falls it dries up very quickly. There are many causes for this lack of rain. It can be due to natural global patterns of air circulation, like in the Sahara desert where the winds are very strong, where it’s naturally very dry and very sunny. In other parts of the world, droughts can be caused when high pressure weather systems last for several weeks. When there is a high pressure system no clouds will form because no water can evaporate. When a high pressure system is over an area for too long there is no precipitation (snow and rain). High pressure systems bring lots of sunshine, but can stop the passage of low pressure systems that bring rain. Unfortunately droughts can be created or at least helped along by people too. Poor practices in farming and too many fertilizers can make the soil lose its moisture and richness. Constant us
