Explain the different causes for drought

The different causes for drought:--

1. Natural causes

Some droughts have occurred naturally, plaguing humankind throughout much of our history. Until recently, naturally occurring droughts were often natural phenomena triggered by cyclical weather patterns, such as the amount of moisture and heat in the air, land, and sea.

2. Altered weather patterns

The distribution of rainfall around the world can also be affected by how air circulates through the atmosphere. When there is an anomaly in surface temperatures, particularly over the sea, air circulation patterns are altered.

This changes how and where precipitation falls around the world and the new weather patterns will most likely throw water supply and demand out of sync, as is the case when earlier-than-usual snowmelt reduces the amount of water available for crops in the summer.

3. Excess water demands

Drought can also result because of an imbalance in the supply and demand of water. As the global human population continues to balloon ________ _______ _____ __________ ________ _____ _______ _______ __________.
