Explanation:
The energy from the sun that reaches the surface of the earth is about 900 W/m2 while actual sun radiation is 1360 W/m. This is because of the Earth's atmosphere layers. This is further explained below.
<h3>What are
Earth's atmosphere layers?</h3>
Generally, there are five primary layers and a number of tertiary layers in the Earth's atmosphere. The troposphere, stratosphere, mesosphere, thermosphere, and exosphere are the principal layers of the atmosphere, from the lowest to the highest.
