Why are temparatures in namib desert lower than kgalagadi desert?

This statement isn't necessarily true. The Namib Desert and the Kgalagadi Desert are both located in southern Africa, and they have similar climate conditions. However, the Namib Desert is located along the coast of the Atlantic Ocean, while the Kgalagadi Desert is located further inland. This difference in location can affect the temperatures in the two deserts.

The Namib Desert is cooled by the cold waters of the Atlantic Ocean, which helps to keep the temperatures relatively mild. The average temperature in the Namib Desert is around 20 degrees Celsius (68 degrees Fahrenheit). In contrast, the Kgalagadi Desert is located further inland, and it does not have the benefit of the cooling effects of the ocean. As a result, the temperatures in the Kgalagadi Desert can be much higher, with average temperatures reaching up to 30 degrees Celsius (86 degrees Fahrenheit).

In general, the Namib Desert is cooler than the Kgalagadi Desert due to its proximity to the Atlantic Ocean. However, there can be some variation in temperatures between the two deserts, depending on the time of year and the specific location.
