Some of it is reflected back into space. Some of it is absorbed by the atmosphere. Some of it is scattered by the atmosphere.
Radiation can occur in all layers of the Earth, but it has the greatest impact on the Earth's surface due to interactions with the atmosphere and the geomagnetic field. Cosmic radiation from space can penetrate the atmosphere and reach the Earth's surface, affecting living organisms and materials.
Roughly 30% of the Sun's radiation is reflected back into space by the atmosphere, clouds, and surface of the Earth, before it reaches the planet's surface. This includes both direct reflection and scattering of solar radiation.
UVC radiation, which has wavelengths between 100 and 280 nanometers, does not reach the Earth's surface because it is absorbed by the ozone layer in the atmosphere. This type of UV radiation is the most harmful to living organisms, but the ozone effectively protects us from its damaging effects. Therefore, while UVA and UVB rays can penetrate the atmosphere and reach the Earth, UVC is completely filtered out.
Radiation from the Sun travels to Earth in the form of electromagnetic waves. It takes about 8 minutes and 20 seconds for this radiation to reach Earth after leaving the Sun.
Yes, most of the UV radiation from stars is blocked by Earth's atmosphere. However, some UV light does reach the surface, which is why we still receive UV radiation from the Sun. This is why we need protection like sunscreen to prevent damage from UV radiation.
the climate changes
Solar radiation reaches the surface of the Earth through the process of electromagnetic radiation emitted by the Sun. This radiation travels through space and reaches Earth's atmosphere, where it penetrates and warms the surface of the planet. The atmosphere helps block harmful radiation while allowing sunlight to reach the surface.
Electromagnetic radiation from the sun, most in the form of visible light.
Energy, in the form of radiation, takes about 8 minutes to reach from the surface of Sun to the surface of Earth.
Radiation can occur in all layers of the Earth, but it has the greatest impact on the Earth's surface due to interactions with the atmosphere and the geomagnetic field. Cosmic radiation from space can penetrate the atmosphere and reach the Earth's surface, affecting living organisms and materials.
Most of the visible light and some of the ultraviolet and infrared radiation from the sun pass through the atmosphere and reach the Earth's surface. Other forms of radiation, such as gamma rays and X-rays, are mostly absorbed by the atmosphere and do not reach the surface.
Roughly 30% of the Sun's radiation is reflected back into space by the atmosphere, clouds, and surface of the Earth, before it reaches the planet's surface. This includes both direct reflection and scattering of solar radiation.
The main sources of energy that reach the troposphere are solar radiation and infrared radiation emitted by the Earth's surface. Solar radiation heats the Earth's surface, which in turn emits thermal (infrared) radiation back into the atmosphere. This energy exchange drives atmospheric circulation and weather patterns within the troposphere.
UVC radiation is absorbed by the ozone layer in the Earth's atmosphere, preventing it from reaching the Earth's surface. If UVC radiation were to reach the surface, it can be harmful to living organisms as it can damage genetic material and cause skin cancer.
Cloud cover influences the amount of solar radiation that reaches Earth's surface because solar radiation cannot reach earth if there is tons of clouds blocking the way
Longer wavelength infrared radiation reaches Earth. This type of infrared radiation is also known as thermal infrared, which is emitted by the Earth's surface and is an important component of the Earth's energy budget. Shorter wavelength infrared, such as near-infrared, is mostly absorbed by the atmosphere and does not reach the surface.
Greenhouse gases absorb shortwave radiation by allowing it to pass through the Earth's atmosphere and reach the surface. Once the radiation hits the surface, it is absorbed and re-emitted as longwave radiation. Greenhouse gases then trap this longwave radiation, preventing it from escaping back into space and causing the Earth's temperature to rise.
