from the Sun strikes Earth's
surface and causes
it to warm
. Some of this heat
then is radiated back toward space. Some gases in the atmosphere, known as greenhouse gases, absorb a portion of this heat
and then radiate heat
back towards Earth
. This keeps Earth warmer
than it would be otherwise.

Anyhow, what is the cause of solar radiation?
In addition to the sun's angle, atmospheric conditions can affect radiation levels. Cloud cover, air pollution and the hole in the ozone layer all alter the amount of solar radiation that can reach the surface. These factors all cause typical radiation levels to differ.
On top of this, how is Earth's solar radiation distributed? About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system. ... The remaining 48% is absorbed at the surface.
Quite as, how does radiation from the sun heat the Earth?
The sun heats the earth through radiation. Since there is no medium (like the gas in our atmosphere) in space, radiation is the primary way that heat travels in space. When the heat reaches the earth it warms the molecules of the atmosphere, and they warm other molecules and so on.

Excessive exposure to the sun is known to be associated with increased risks of various skin cancers, cataracts and other eye diseases, as well as accelerated skin ageing. It may also adversely affect people's ability to resist infectious diseases, and compromise the effectiveness of vaccination programmes.
Sunlight, also called sunshine, solar radiation that is visible at Earth's surface. The amount of sunlight is dependent on the extent of the daytime cloud cover.
Need for Protection from Solar Radiation: Solar Screens are one option to significantly reduce or prevent solar heat gain and transference of solar radiation, depending on the screen thickness chosen. Solar screens filter and block the damaging UV Rays that cause color fading on floors, walls, artwork, and furniture.
What Common Materials Absorb the Most Energy From the Sun?
- Water: Global Heat Reservoir. All water absorbs a lot of energy from the sun, with the amount absorbed directly dependent on how large the body of water is. ...
- Spirulina: Efficient Algae. ...
- The Concrete Jungle. ...
- Darker Means Hotter. ...

The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth's surface while around 30% is reflected back to space and does not heat the surface.
Low, thick clouds primarily reflect solar radiation and cool the surface of the Earth. High, thin clouds primarily transmit incoming solar radiation; at the same time, they trap some of the outgoing infrared radiation emitted by the Earth and radiate it back downward, thereby warming the surface of the Earth.

Without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.
Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
