Why is Africa hotter than US?

It is not necessarily true that Africa is hotter than the United States. While parts of Africa are indeed very hot, other parts can have cooler climates. For example, the Sahara Desert in North Africa is known for its extreme heat, with temperatures sometimes exceeding 50 degrees Celsius (122 degrees Fahrenheit). On the other hand, the US state of Alaska, located in the northern part of the country, experiences very cold temperatures, often dropping below freezing point. There are regions in the US, such as the Death Valley in California, that can reach extremely high temperatures, but the overall climate of the US varies significantly from region to region.
