What heats earths atmosphere?
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.
How the three types of thermal energy warm earths atmosphere?
Solar radiation—The sun emits energy in the form of electromagnetic radiation, which heats the Earth's atmosphere. Infrared radiation—The Earth's surface absorbs solar radiation and emits heat energy in the form of infrared radiation, which warms the atmosphere. Convection—The warmed air near the Earth's surface rises, carrying heat energy higher into the atmosphere and contributing to the overall warming.
What radiation heats lower atmosphere?
In the lower atmosphere, the main sources of heating are solar radiation absorbed by the Earth's surface and the subsequent release of infrared radiation, as well as the absorption of some of this infrared radiation by greenhouse gases like water vapor and carbon dioxide, which further warms the lower atmosphere through a process known as the greenhouse effect.
What is the energy exchange between space the atmosphere and earths surface produce?
The energy exchange between space, the atmosphere, and Earth's surface produces a balance of incoming solar radiation and outgoing thermal radiation. Solar energy is absorbed by the Earth's surface, which then emits thermal radiation back into the atmosphere. Greenhouse gases in the atmosphere trap some of this thermal radiation, leading to the warming of the Earth's surface.
Why is the atmosphere is heated cheifly by radition from Earth's surface rather than by direct solar radiation?
The atmosphere is heated chiefly by radiation from Earth's surface because the Earth's surface absorbs solar energy and emits it as infrared radiation. This infrared radiation is then trapped by greenhouse gases in the atmosphere, causing the atmosphere to be heated. Direct solar radiation contributes to heating the Earth's surface, which in turn warms the atmosphere through convection and radiation.
How does solar radiation leave earths atmosphere?
Solar radiation leaves Earth's atmosphere through a process called reflection and absorption. Some of the radiation is reflected back into space by clouds, gases, and particles in the atmosphere. The remaining radiation is absorbed by the surface of the Earth, where it is converted into heat energy.

What three gasses present in Earths atmosphere absorb solar radiation?
Carbon dioxideMethaneNitrous Oxide
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.

Why is earths magnetic field impotant?
The earth's magnetic field is important in that it prevents the sun's solar radiation from killing life on earth by wiping out the earth's atmosphere and deflecting dangerous radiation.
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.

The atmosphere is heated chiefly by radiation from Earth's surface because the Earth's surface absorbs solar energy and emits it as infrared radiation. This infrared radiation is then trapped by greenhouse gases in the atmosphere, causing the atmosphere to be heated. Direct solar radiation contributes to heating the Earth's surface, which in turn warms the atmosphere through convection and radiation.
Which layer of the atmosphere does not absorb solar radiation?
Troposphere does not absorb solar radiation. All other layers do not absorb.
How has the earths atmosphere changed?
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.
