Question

How is heat trapped within earth?

Answer 1

Answer:

During the day, the Sun shines through the atmosphere. Earth's surface warms up in the sunlight. At night, Earth's surface cools, releasing heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere.

Answer 2

The process of heat getting trapped within earth.

• A minimal amount of greenhouse gases like carbon dioxide, water vapor, and methane are present in the earth's atmosphere.
• These are crucial in keeping the Earth's temperatures stable so that it does not get too cold for life to exist.
• On Earth, the Sun is a significant energy source. Visible, infrared, and ultraviolet light are the principal forms of energy that reach Earth, and the majority of that energy flows through the atmosphere to warm the surface.
• This solar energy is absorbed by the Earth and then reemitted as infrared light, which is invisible. The greenhouse effect traps this energy.
• Owing to their unique forms, greenhouse gases are efficient at absorbing infrared light that the Earth emits. Methane is particularly effective at doing this, and other greenhouse gases like carbon dioxide are also capable of doing this, though less effectively.
• The energy is transferred from these gases to other greenhouse gases and then back to the Earth's surface. Because of their forms, nitrogen and oxygen are not very good at absorbing infrared light.
• Through the combustion of fossil fuels like coal and oil for energy, humans have increased the amount of carbon dioxide in the atmosphere.
• Earth's surface temperatures rise as greenhouse gases are added to the atmosphere.
