Given data: Incoming energy from the sun is 100%.

find: How do the outgoing energy emits to space balance this value?

Explanation:

The balance between incoming and outgoing energy from the sun is maintained through the Earth’s energy budget. The Earth receives energy from the sun primarily in the form of sunlight, and it emits energy back into space in various forms.

Step 2 of 2

The balance between incoming solar radiation (energy from the Sun) and outgoing terrestrial (Earth) radiation is crucial for maintaining Earth’s energy equilibrium.

This balance is described by the concept of Earth’s energy budget. Here’s a simplified explanation:

Incoming Solar Radiation (Insolation):

  1. The Sun emits energy in the form of electromagnetic radiation, primarily in the visible and near-infrared spectrum.
  2. This incoming solar radiation is the energy that reaches the outer atmosphere of Earth.

Absorption by Earth: 3. About 30% of the incoming solar radiation is reflected back to space by clouds, atmospheric particles, and Earth’s surface (albedo effect).

  1. The remaining 70% is absorbed by Earth’s surface, warming the planet.

Outgoing Terrestrial Radiation: 5. Earth, being warmer than outer space, emits energy back into space in the form of infrared radiation (terrestrial radiation).

  1. This outgoing terrestrial radiation is balanced with the incoming solar radiation for Earth to maintain a roughly constant temperature.

Balance and Equilibrium: 7. The balance between incoming solar radiation and outgoing terrestrial radiation is crucial for maintaining Earth’s temperature and climate.

  1. If there were an imbalance, such as increased absorption or reduced reflection, it could lead to global warming or cooling, affecting Earth’s climate.

Explanation:

The balance between incoming and outgoing energy is achieved when the amount of energy absorbed by the Earth equals the amount of energy emitted by the Earth. This balance helps maintain the Earth’s average temperature and climate.

Final solution

In summary, Earth absorbs solar energy and re-emits it as terrestrial radiation to achieve a balance. This energy balance is fundamental for maintaining Earth’s climate and temperature. Changes in this balance, such as those induced by human activities, can have significant implications for the planet’s climate.
