why doesnt the suns radiation cause earth to burn up when the surface faces the sun and freeze when its not...

The atmosphere modulates the amount of temperature change that can occur.  Clouds block some radiation from reaching the earth's surface during the day, and hold in heat escaping into space during night time.  The moon, lacking an atmosphere but orbiting at the same distance from the sun, experiences much larger temperature swings during the lunar day/night cycle.

Almost all of Earth's internal temperature is radiated outward from its molten core. There is also some heating, particularly nearer the Earth's surface, resulting from physical stresses brought on by Earth's rotation, motion around the Sun, and by gravitational interaction with the Moon.

The earth is protected by the Ozone Layer, which helps us from the sun's damaging uv rays.  As people pollute the air, the ozone layer becomes damaged and evenutally will diminish causing the sun's damaging rays to enter the earth's atmosphere increasing temperatures.  The increase in temperature would cause areas of extremely cold temperature where icebergs are found to become warmer; thus causing icebergs to begin melting.  The increase in temperature will also cause many of the plants that survive and grow in the tropics to die.\n\nAir pollution contribuites to GW by causing the ozone layer to dissapear, leaving sections of "holes" where the powerful ray's of the sun will cause increase in temperatures damaging life forms to include plants, animals that survive on such plants, polar caps melting which could affect the animals (polar bears, penguins, etc).

Hai shishi.. Assume that u r in pluto,whether it's day or night the temperature always remains freezing! Likewise when night comes obviously our earth rotates and turn the other side the previous 12 hours jouney.\n          Then the gradual rotation makes us again face sun.Thus if u set up a thermometer at the outside areas u will notify the increase in temperature along with the rotation of clocks.\nremember..'THE EARTH IS SPHERICAL!'

Our sun will not supernova.  It will, over a very long time, expand into a relatively small red giant, which will have a diameter greater than the Earth's orbit.\n\nLong before that the Earth will have become far too hot to live on, but the process will be very, very slow -- it'll take over a billion years -- not a giant explosion.\n\nSorry to disappoint you.  I know, you sound like you were looking forward to it.  Funny how many people answering this question think otherwise.  I guess that's the irony of the internet for you.\n\nSee the link below for all the details:

A full description is beyond this web site. \n\nGreenhouse gases keep the earth warmer than it would be otherwise. Greenhouse gases like water vapor, carbon dioxide and methane prevent heat from the earth from escaping into space. \n\nHumans might be increasing the number of greenhouse gases in the air. This might cause it to get warmer. Some call this global warming. \n\nHowever, it might cause storms to get worse, or it to get colder too. It is more properly called global change.

Well the sun is getting hotter and will continue to do so until most of  the hydrogen is converted to helium it will then expand to become a red giant. \n\nHowever the effects of this will be minute compared to processes on the earth, IE its tilt, orbit, and mankind's carbon emissions and of cause the deforestation. It must be remembered that we are in an interglacial period and the earth has been a lot warmer than it currently is. The problem is that the increase in temperature is the largest in thousands of years. BUT, when the last ice age finished the temperature rise in approx 50 years was much higher than our rise in 200 years so it is all relative.\n\nThe "freak" weather conditions on other planets may well be perfectly normal for them, remember at best we have only had probes in regular orbits around the other planets for at best 20 years with the resolution capacity to take images that show them.\n\nThe biggest problem is that although in UK we have large taxes on fuel much bigger than any proposed tax by most over governments, there is no unified effort to get us off fossil fuels, if there was someway of getting me out of my 1.2 litre small car than fine, But whats the point when someone in an other country with a 4 litre car still pays less than me to go the same distance?

the sun..... the sun is the only thing responsible for warming the earth. Dont get me wrong ...pollution and greenhouse gases also contribute. But they are not the only reason. We are in a short period of warm temperatures on earth. A small window in time. We just got out of an ice age about 12-15ooo years ago. We have had longer periods of global Ice Ages than we have of global warm periods in the last few million years.... Did u know that a violent volcano can spew enough greenhouse gas into the atmosphere to warm our atmospheric temperatures several degrees. Pollution does the same thing but on a smaller scale. This gas traps the earths heat from escaping back into space. Its like a blanket for our atmosphere. Then the earth gets warm, and creates more water vapor from the oceans. More water vapor means more clouds. More clouds mean less sunlight hitting the surface of earth, less sunlight means less heat, less heat means more ice.. and we go back into an ice age.... then the earth fixes herself, we start to get warmer.... and we go on and on.... Its been happening like that for millions of years. If it wasent for global warming we wouldnt be alive and the earth would be covered with seals, penguins, polar bears and wolly mammoths.

No its not necessarily closer to the sun(visit usgs.org) and even if its closer, it may be closer by 0.000001%.What big difference does that make.Its the difference in air pressure that makes the peaks colder.The higher you go up in the earth's atmosphere,the pressure decreases.And even an object 90% closer to the sun may not be that hot.

The magnetic field prevent excess of radiation and matter from sun to approch the earth. For example when an explosion occurs on the sun's surface...\nAs we know that explosion release a lot of energy which try to reach the earth. The magnetic field of earth block them. That why in polar region we see those green waves in the sky at night...\n\nWithout those explosion, the sun still send excess of light. The light contain excess of ultraviolet radiation and the percentage is too small for the magnetic waves of the earth to block it.\n\nHence the ozone layer filters the light and allow little ultraviolet rays to enter the atmosphere...

It is mainly from residual heat from when the earth first formed & the breakdown of radioactive elements w/in the earth. Pressure from the overlying material can also create heat.\n\nThe earth is actually cooling but it will take a very long time for it to "completely" cool.

I give you a couple of hints:\n\nThe sun radiation heats Earth´s surface generating a  movement of air due to the phenomenon of convection: hot air (near the surface) goes up while cold air (high layers of atmosphere) goes down. The air can be wet of dry depending the zone that is heated by the sun (most of the water in atmosphere results from the evaporation of oceanic masses when sun radiation hits the superficial waters for example). \n\nNormally, hot and wet masses of air travel to the North of the planet while the cold and dry travels to the south hemisphere. The encounter of these masses can cause violent hurricanes in some zones of the planet, droughts in others and heavy rains in some others.\n\n(If you need more information I have to tell you that you should travel to www.wikipedia.org)\n\nHope it helps you!\n\nGood luck!

Atmosphere has a very low heat capacity compared to hydrosphere. It will react strongly on short term (well below diurnal) changes, like insolation (amount of energy absorbed by the sun).

Space near the earth is actually filled with a gas called the interplanetary medium (see first source). This gas, which is mostly gas coming from the sun, is quite hot, around 100,000 degrees C. But, it's also only 10^-18th the density of sea level air, so it carries very little heat.\n\nAir is relatively thick, so we're used to conduction and convection determining an objects temperature.  There's very little of either in space, so radiation dominates.  The sun's light is about twice as strong in space as it is on earth.  How hot this heats an object depends on the objects shape and color, but it's fair to say that most things will heat up to a few hundred degrees. \n\nBecause there's no air in space, everything looses heat very slowly, like being in a thermos. So, anything that produces heat, like a human body or machinery, will gradually warm up--space suits have built-in coolers to deal with this. \n\nIf you're out of the sunlight and have used up all your internal energy, you eventually cool down to about -25 to +25 C.  Infrared radiation from the earth is what prevents you from getting colder.  If you were also far away from the earth, you'd cool down to something between -240C and -270C.

Well, the solar energy received by Earth is considered a constant. The heat from residual internal sources is considered to be minimal compared to the amount received by the Sun. Also the idea of a constant temperature is relative to the scale of time and space you choose. I'm not going into variations possibly due to sunspot occurrence, orbital, precession, axis wobble, volcanic, meteor impacts, nor seasonal changes.\nHere is a general model of energy transfers, heating and temperature.\nThe amount and wavelength of energy absorbed by a substance or blackbody causes it to heat to a particular temperature and radiate at a particular wavelength. Though the atmosphere is of a layered, mostly permanent composition and the Earth surface is not contiguous, this helps understand the effect of radiant energy on Earth. The reactions of the Sun make it so hot the radiant energy is essentially short wave (high frequency). Consider 100 units of solar sw received by the Earth (insolation), the atmosphere absorbs 25 (mostly due to ozone in the stratosphere) and reflects or scatters 25, while the water/terrain at the surface absorbs 45 and reflects 5. As the terrain and atmospheric gases absorb the sw energy they heat, but not too hot, and radiate long wave energy (low frequency).\nThe Earth surface radiates 104 units of lw - 100 to the atm and 4 out to space. The atm radiates 154 units - 88 back to Earth and 66 out to space. How can this happen and where does the additional energy come from?\nThere are several parts of this development.\nPart of the reason is the atm is a layered, mostly gaseous composition that exchanges energy amongst the layers, the Earth surface, and out to space. Another part is the other ways energy is transferred, such as the convection and turbulent flow of gases that transfer latent and sensible heat between the surface and atmosphere. You experience this when water is transported and goes through its various phases to develop the local weather.\nLets give these processes values. Convective processes values account for 22 units of latent heat and 7 of sensible heat.\nNow tally the total energy absorbed by the surface as 45 + 88 = 133 and the atm as 100 + 25 = 125. The convective processes ensure the energy balance by transferring 29 units of energy from the surface to the atm to obtain the 104 units and 154 units mentioned earlier. This leads to development of a mean global temperature as we know it at 15 deg C.\nNotice how much the atm is relied upon to transfer energy out to space? Changing the atm composition with additional variable/ long term gases, particulates, and aerosols can alter the events.\nParticulates and some gases can cause more reflection at the top of the atm resulting in less insolation, less heating, and lower temperature. Addition of some gases into the atm can increase the absorbtion of lw radiation or prevent it from being transferred to space. When it comes back to the surface, additional heating and a temperature increase will result if the convective processes cannot adjust for the increased energy.

The simplest answer I can give you is that the air doesn't absorb much heat from the sun (sunlight passes through it), while the ground does (the exception is ozone, which does absorb more radiation, and thus higher up in the atmosphere, there is actually a warm layer).  So the ground is actually what is doing the heating, and the higher you go in the atmosphere, the further you are from the ground, the cooler the temperatures.\nOf course mountains are ground... but air at the same height mixes about quite a lot, so while air near a mountain might be a bit warmer... the air in other places at the same height is well above the ground, so it's cooler overall.\n\nIn addition, air cools as rises, a second reason why its cooler higher up in the troposphere.\n\n\nSpace is really really really cold!  It's for the same reason.  The light from the sun itself isn't hot... it's when its absorbed by something, which heats it up.\n\nHope this makes sense, let me know if there is anymore I can help with here,\nGod bless,\nShane
