Which is a cause of drought?

There are several potential causes of drought, including:

1. Lack of precipitation: Below-average rainfall can lead to dry conditions and decreased water availability, resulting in drought.

2. High temperatures: Hot weather can increase the rate of evaporation, drying out soils and reducing available water for plants, leading to drought conditions.

3. Climate change: Changes in climate patterns, such as shifting weather patterns and increasing temperatures, can contribute to more frequent and severe droughts.

4. Human activities: Deforestation, overuse of water resources, and other human activities can exacerbate drought conditions by reducing the availability of water and disrupting natural water cycles.

5. Natural variability: Droughts can also occur as part of natural climate variability, without any clear external cause.
