Why Are These Deserts So Hot?
The extreme temperatures in these deserts are due to several factors:
- Geographical Location: Most of these deserts are located near the equator, where the sun’s rays are most direct.
- Lack of Vegetation: Sparse plant life means less shade and more absorption of heat by the ground.
- High Pressure Systems: These regions often have high-pressure systems that lead to clear skies and intense solar radiation.
