Question

3 causes of drought and explain them

Answer 1

1. Climate variability: Drought is a natural occurrence caused by changes in weather patterns and climate variability. Factors such as El Niño and La Niña can cause unusual patterns of rainfall, which can result in prolonged dry spells.

2. Human activities: Human activities such as deforestation, land use change, and overuse of water resources can contribute to drought. Deforestation reduces the amount of rainfall that the land can absorb, while overuse of water resources depletes groundwater reserves, leaving insufficient water for crop irrigation and drinking water.

3. Natural disasters: Natural disasters such as wildfires, volcanic eruptions, and earthquakes can also cause droughts. Wildfires can destroy vegetation in large areas, reducing the amount of water that the land can absorb, while volcanic eruptions and earthquakes can alter the geology of an area, reducing the amount of accessible water for crops and human consumption.
