Two of the most famous deserts in the world are the Sahara and the Namib. Do a quick internet search and record their latitudes (in degrees north/south). How does the explanation of air circulation patterns above help explain their geographic location?

Sure, let's break this down step by step.

1. Internet Search for Latitudes:

   • Sahara Desert: The Sahara Desert is located at approximately 25.0000° N latitude.
   • Namib Desert: The Namib Desert is located at approximately 23.0000° S latitude.

2. Explanation of Air Circulation Patterns:

   • The Earth's air circulation patterns are largely driven by the uneven heating of the Earth's surface and the Earth's rotation. This creates a pattern of air movement known as the Hadley, Ferrel, and Polar cells.

   • The Hadley cells are the low-latitude overturning circulations that have air rising at the equator and air sinking at roughly 30° latitude. This is why most of the world's deserts are located at these latitudes, as the sinking air creates high-pressure zones, leading to dry and arid conditions.

   • Therefore, the Sahara Desert, located at 25° N, and the Namib Desert, located at 23° S, are both located near the 30° latitude line. This is consistent with the air circulation patterns described above, as these latitudes are where air tends to descend, creating the arid conditions that characterize desert biomes.
