Short wavelength radiation such as Ultraviolet fall to absorption spectrum band of Ozone. Ozone absorb UV and re-emitted the radiation in the range of infrared or thermal range radiation.

How much amount of solar energy by earth every day?
The average solar radiation hitting the planet is considered to be about 352 watts/meter squared. Total radiation hitting our atmosphere is about 1366 watts/meter squared. The rest of this energy is absorbed or reflected by the atmosphere.
Reflection and absorption by the atmosphere prevent some?
The sun's total energy package. There are about 1355 watts hitting each meter of atmosphere. Roughly 375 watts reach our planet. This amount varies greatly on weather conditions. Water vapor (clouds) provide most of the feedback loop.It is believed that man's contribution of 0.28% of the total green houses gases may have some affect on the current warming. Science suggests (and data supports) that this may well not be the issue. While man has been steadily increasing his contribution of CO2 to the atmosphere (now reaching 6% of total CO2 production and 0.28% of total GHG) we are seeing a steady decline in temperature worldwide. The crest seems to have been in 1998. The start point of this warming was about 6000 years ago. Of the 11 degrees (C) of warming we have verified, only 0.2 has occurred since man started using fuel.Reflection and absorption by the atmosphere prevent some solar radiation from reaching the earth's surface.
Does the atmosphere gets heated up by radiation?
Acted on by the combined effects of the earth's motions and energy from the sun, our planet's formless and invisible envelope of air reacts by producing an infinite variety of weather. Solar radiation hitting the earth, a sphere which is tilted on its axis, puts into effect differential heating of the earth's surface. This affects weather and climate all across the globe. For example, the tropics along the equator get a lot more heat than at the poles. The air at the equator is heated. This air becomes less dense and rises. This rising air creates low pressure at the equator. The rising air cools and as it cools water vapor condenses with increasing altitude. This creates the high rainfall that we get at the Intertropical Convergence Zone in the tropics. This is just one example of how solar radiation affects weather in one specific area of the earth. Solar radiation also is what drives atmospheric circulation or the winds across the globe. We all know that heat rises, right? Well, the excess heat in the tropics rises. Then this rising air is circulated around the globe due to the Coriolus force, or the force of the rotation of the earth. The earth then gets major wind belts along it's surface which in turn affect weather all over the world.
What are the characteristics properties of earth that make life possible as we know it?
First of all, we are in what the scientists call the 'Goldilocks zone' because we are in the small region of space which is cold enough to hold water without it boiling, and warm enough to allow it to stay a liquid. Secondly, there is the atmosphere which contains 20% oxygen, allowing is to breathe and 78% Nitrogen, 1% Argon, 0.04% Carbon dioxide and various other gases. The atmosphere also blocks harmful radiation from the sun, such as the ozone layer blocking much Ultra violet radiation from reaching us. This atmosphere also prevents meteors from hitting the earth, producing shooting stars. There is also the abundance of plants which use the light from the sun to photosynthesise and produce oxygen, enriching our atmosphere. It is thought that if plants were to be put on Saturn's moon Titan, the mainly nitrogen atmosphere would begin to contain oxygen and therefore allow life to develop.
Is the earths lithosphere the rigid outer shell of the planet?
The atmosphere is an outer layer of gas on a terrestrial planet. A hole in the ground caused by a meteor hitting a planet is a crater.
What causes auroras on Earth?
The suns radiation hitting our atmosphere
What cause Earth's auroras?
The suns radiation hitting our atmosphere
Is sunlight that hits the Earth straight on dimmer or brighter?
Dimmer or brighter than what? Sunlight hitting the earth straight-on, as at the equator, is brighter, hotter and includes more intense ultraviolet radiation. Sunlight at an angle, the poles, for example, is less intense because it has to travel through more atmosphere. The atmosphere acts as a filter, effectively dimming the sun's radiation.
How much amount of solar energy by earth every day?
The average solar radiation hitting the planet is considered to be about 352 watts/meter squared. Total radiation hitting our atmosphere is about 1366 watts/meter squared. The rest of this energy is absorbed or reflected by the atmosphere.
How much sunlight is absorbed into the atmosphere?
Our current atmosphere absorbs about 16% of the incoming radiation. Another 30% is reflected as it is entering. Some is scattered into space through deflection. Less then half of the energy hitting the atmosphere makes it to our planet. Most of the energy hitting bounces off of it as visible light. (albedo effect). Visible light will pass through the atmosphere pretty much unabated. A portion of the energy hitting our planet is absorbed by planets or converted nto infrared energy. The infrared radiation is slowly released during the night hours. A portion of this is absorbed by greenhouse gases and that energy is also released during the evening to keep the planet warm and alive.
Reflection and absorption by the atmosphere prevent some?

What is incident radiation?
Radiation is a general term for the energy transmitted through space.Incident radiation is a term used when referring to the radiation hitting a specific surface. For instance, the incident radiation for a solar panel is the total amount of radiation hitting the surface of the solar panel. This is in contrast to direct beam radiation which refers to only that radiation which arrives in a strait line from the sun. (It differs in that total incident radiation includes additionally the component of diffuse radiation.)
Why do space shuttles get hot?
They heat up on their return to earth because of simple friction. The shuttle hitting the atmosphere slows its rate of speed and causes the outside of the craft to get very hot. It is exactly the same as a 'shooting star' hitting our atmosphere.
Auroras are caused by what hitting the atmosphere?
Auroras are caused by charged solar particles colliding with atoms of oxygen and nitrogen in the ionosphere, which is the highest level of the atmosphere.
Effects that charged particles have hitting gas particles in the Earth's atmosphere?
Aurora. Northern Lights.
Does a 3 inch diameter magnifying glass produce heat?
Only after the concentration of sun radiation.No, it cannot produce any heat, but it can focus all of the solar radiation hitting the lens into a much smaller area.
What is an example of Reflection of light?
Sun light hitting the atmosphere of the earth.
