Question

energy and temps: average annual solar radiation is not equal across all surfaces of the earth. where in north america do you find the highest watts per square meter? high elevations sahara desert atacama desert florida southwest us/nw mexico

Explanation:

The Southwest US and NW Mexico have clear skies, low - humidity, and are at relatively high latitudes in North America, which allow for more solar radiation to reach the surface compared to other regions in the list. The Sahara Desert is in Africa and the Atacama Desert is in South America, so they are not relevant to North America. Florida has more cloud cover and humidity compared to the arid Southwest. High elevations alone do not guarantee the highest solar radiation in North America.

Answer:

Southwest US/NW Mexico
