Question

The ______ % of insolation is absorbed by the atmosphere.

Options

• 14

• 34

• 51

• 35

Answer 1

The 14 % of insolation is absorbed by the atmosphere.

Explanation:

During insolation, about 14% of the incoming solar radiation is absorbed by the atmosphere, including ozone. Additionally, 35% is reflected back into space, and 51% reaches the Earth’s surface. The atmosphere absorbs less of the incoming solar radiation compared to the amount of terrestrial radiation it absorbs from the Earth’s surface. This absorption by the atmosphere helps regulate the temperature on Earth and prevent extreme temperature variations.
