Infrared radiation
The effect that occurs when solar radiation is absorbed by the Earth's surface and then re-radiated into the atmosphere, where it gets trapped, is known as the greenhouse effect. This process involves greenhouse gases, such as carbon dioxide and methane, absorbing and re-emitting infrared radiation, which warms the atmosphere and the Earth's surface. While this natural phenomenon is essential for maintaining a habitable climate, human activities have intensified the greenhouse effect, leading to global warming and climate change.
Visible light is an insignificant portion of the solar radiation that warms the Earth. The sun's infrared radiation, also known as 'heat', is responsible for virtually all of it.
The greenhouse effect helps moderate Earth's temperatures by trapping heat in the atmosphere. When sunlight reaches the Earth's surface, some of it is absorbed and then re-radiated as infrared radiation. Greenhouse gases, such as carbon dioxide and methane, absorb this infrared radiation and re-emit it in all directions, including back towards the surface. This process keeps the planet warm enough to support life by maintaining a stable temperature range.

Infrared radiation
The trapping of energy from the sun by Earth's atmosphere is called the greenhouse effect. Solar radiation passes through the atmosphere to heat the Earth's surface, which then emits infrared radiation. Some of this infrared radiation is trapped by greenhouse gases in the atmosphere, such as carbon dioxide and water vapor, creating a warming effect that helps maintain Earth's temperature.

Infrared radiation from the sun warms the Earth's surface. This heat energy is then radiated back into space as longwave infrared radiation. This process is known as the greenhouse effect.

The sun's energy reaches the Earth in the form of sunlight (solar radiation), which is absorbed by the Earth's surface. The surface then heats up and radiates heat back into the atmosphere, creating what is known as the greenhouse effect. Some of the heat is trapped by greenhouse gases, such as carbon dioxide, which keeps the Earth warm enough to sustain life.
The sun heats the atmosphere. Solar radiation largely passes through the atmosphere and warms the surface of the earth. The earth then radiates heat up into the lower levels of the atmosphere where greenhouse gases warm. The warmed greenhouse gases then continue to radiate heat in all directions warming the atmosphere and again the earth's surface.
infrared radiation, which contributes to the greenhouse effect. This process helps trap heat in the atmosphere, leading to the warming of the Earth's surface.
the greenhouse
The greenhouse effect is more pronounced for the earth's surface. Heat rising from the surface is trapped by greenhouse gases. These warm gases heat the air around them as well, also, as the earth' surface again.
