At the approximate latitudes of 30°N and 30°S, the air is relatively dry, and high evaporation is experienced. Why? Atmospheric convection patterns result in air rising at these latitudes. Atmospheric convection patterns result in air sinking at these latitudes. O There is more precipitation than evaporation at these latitudes. O There is significant sea ice formation at these latitudes.

Question
### Understanding Atmospheric Conditions at 30° Latitudes At the approximate latitudes of 30°N and 30°S, the air is relatively dry, and high evaporation is experienced. This phenomenon occurs due to specific atmospheric convection patterns. #### Question: Why is the air relatively dry with high evaporation at these latitudes? #### Answer Choices: 1. **Atmospheric convection patterns result in air rising at these latitudes.** 2. Atmospheric convection patterns result in air sinking at these latitudes. 3. There is more precipitation than evaporation at these latitudes. 4. There is significant sea ice formation at these latitudes. #### Correct Answer: - **Atmospheric convection patterns result in air rising at these latitudes.** ### Explanation: At approximately 30°N and 30°S, the Hadley Cell, a large-scale atmospheric convection current, plays a crucial role. In this cell, air rises near the equator, creating an area of low pressure and lots of precipitation. When this air moves towards 30°N and 30°S, it cools and sinks, creating a high-pressure area. This sinking air is dry, leading to a reduction in cloud formation and precipitation, and an increase in evaporation. This is why regions at these latitudes, such as deserts, tend to have dry climates.
