Causes of Drought
There are several factors that can contribute to the occurrence of drought. These include:
1. Less rainfall:
- Insufficient precipitation is one of the primary causes of drought.
- When there is a significant decrease in the amount of rainfall over an extended period, it can lead to water scarcity and drought conditions.
2. High temperature:
- Increased temperatures can intensify the evaporation rate, leading to the drying out of water bodies, soil, and vegetation.
- When temperatures rise above average, it can cause moisture to evaporate more quickly, exacerbating drought conditions.
3. Dry winds:
- Dry winds, also known as hot and dry winds, can worsen drought conditions.
- These winds have low humidity and high temperatures, causing moisture to evaporate rapidly from soil and vegetation, leading to increased aridity.
Therefore, the correct answer is D: All of the above. All the mentioned factors contribute to the occurrence and severity of drought.

Causes of Drought:
Less Rainfall:
- One of the main causes of drought is a significant decrease in rainfall in a particular region.
- When there is less rainfall than usual over an extended period, it can lead to water scarcity and drought conditions.
High Temperature:
- High temperatures can also contribute to drought conditions by increasing evaporation rates.
- When temperatures are high, water evaporates more quickly from the soil, rivers, and lakes, leading to a reduced water supply.
Dry Winds:
- Dry winds can exacerbate drought conditions by further drying out the soil and vegetation.
- These winds can also increase the rate of evaporation, making it harder for plants to access the water they need to survive.
Summary:
- Drought can be caused by a combination of factors, including less rainfall, high temperatures, and dry winds.
- These factors can work together to create water shortages and dry conditions in an area, leading to drought.
