Where do incoming solar radiation/ energy end up once they reach the earth's atmosphere?

1 answer

Incoming solar radiation or energy that reaches the Earth's atmosphere can be distributed in several ways:

1. Absorbed by the Earth's surface: A significant amount of incoming solar radiation is absorbed by the Earth's surface, where it is converted into heat energy. This process warms the surface of the Earth and contributes to the planet's overall temperature.

2. Reflected back into space: Some of the incoming solar radiation is reflected back into space by clouds, aerosols, and the Earth's surface. This reflects a portion of the energy away from the Earth, contributing to the planet's overall energy balance.

3. Absorbed by the atmosphere: A small portion of incoming solar radiation is absorbed by gases in the Earth's atmosphere, such as ozone and carbon dioxide. This absorption contributes to atmospheric warming and can affect the planet's climate.

4. Used in the photosynthesis process: Some solar energy is absorbed by plants and used in the process of photosynthesis, where it is converted into chemical energy to fuel the growth and development of plants.

Overall, incoming solar radiation is an essential source of energy for the Earth, driving many of the planet's processes and sustaining life on our planet.
