Because it is generally of a very high energy level, allowing it to be transmitted (rather than absorbed, reflected, or scattered off of molecules of gases or larger particles) straight to the ground. This has to do with the size of these particles relative to the very short wavelength of this radiation, and also to the preference of these molecules of gas to absorb gases of different wavelengths. Though in reality, quite a bit of it IS absorbed by gases, scattered by particles, and reflected by clouds. This is the biggest reason it remains so cold in polar regions in the summer, even when there are 24 hours of sun: it must pass through such a thick layer of atmosphere due to the tilt of the sphere of the Earth, that only a relatively small amount can make it to the surface.
When it heats up the surface of the Earth, which then emits its own radiation (at a much longer wavelength, and therefore lower energy level, than the sun because the Earth is much cooler than the sun), this "longwave radiation" tends to get absorbed much more readily by the atmosphere, and this is the essence of the greenhouse effect.
What else can I help you with?
How does solar radiation reach the surface of the earth?
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.
What kind of radiation passes through the atmosphere and reaches the earths surface?
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.
What is a trapping of energy from the sun by earths atmosphere?
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.
What is the source of radiation for both the Earth's atmosphere and the greenhouse?
The primary source of radiation for both Earth's atmosphere and the greenhouse effect is the sun. Solar radiation warms the Earth's surface, which then emits infrared radiation. Some of this infrared radiation is absorbed by greenhouse gases in the atmosphere, trapping heat and warming the planet.
What does the atmosphere absorb to protect earth?
The atmosphere absorbs harmful radiation from the sun, such as ultraviolet (UV) rays, through the ozone layer. This protection helps prevent this radiation from reaching the Earth's surface and harming living organisms.
How does energy transfer from sun to the atmosphere?
radiation can occur through a vacuum
How does heat from the sun reach you?
Heat from the sun reaches you through a process called radiation, where electromagnetic waves travel through space and warm up the Earth's atmosphere. These waves pass through the vacuum of space until they reach the Earth's atmosphere, where they are absorbed and contribute to the overall temperature of the planet.
How and why does solar altitude affect the intensity of solar radiation received at the Earth s surface?
The higher in the sky the sun is the more solar radiation received at the surface. This is because as the sun gets higher in the sky, there is less atmosphere blocking the sun's rays. Imagine the sun going through the atmosphere at a 90 degree angle. The thickness of the atmosphere let say is x thick. As the sun hit the surface at a lower angle, the thickness of the atmosphere has to go through more atmosphere to get to the surface. So the thicker atmosphere blocks more of the sun's rays.
What in the atmosphere has a uv ray from the sun?
Ultraviolet radiation from the sun passes through the atmosphere and reacts with plants, animals and the soil and water - unless it is absorbed by chemical reactions that it initiates in the upper atmosphere.
Why is heat from the sun transferred through radiation?
Heat from the sun is transferred through radiation because electromagnetic waves, such as light and infrared radiation, are emitted by the sun and travel through the vacuum of space to Earth without the need for a medium. This radiation is absorbed by the Earth's atmosphere and surface, causing an increase in temperature.
How is thermal energy transferred from the sun to earth?
Thermal energy from the sun reaches the Earth through radiation. The sun emits electromagnetic radiation, including visible light and infrared radiation, which travels through the vacuum of space and heats the Earth's atmosphere and surface upon contact.
When heat from the sun comes through the atmosphere and heats earth is called what?
This type of heat transfer is called radiation.
The lower atmosphere is directly warmed by?
By the emission of the terrestrial radiation. Terrestrial radiation is emitted in the infrared long-wavelength part of the spectrum. It is terrestrial radiation rather than solar radiation that directly warms the lower atmosphere.
How does solar radiation reach the surface of the earth?
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.
How does energy transfer from the sun to earth and the atmosphere?
Energy from the sun reaches the Earth through electromagnetic radiation, mostly in the form of visible light. This energy heats the Earth's surface, which in turn warms the atmosphere through convection and radiation. Some of the sun's energy is also absorbed by the atmosphere, contributing to its overall temperature and driving weather patterns.
What kind of radiation passes through the atmosphere and reaches the earths surface?
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.
