Light goes from the sun to the earth where it's absorbed and radiated with a lower frequency. This lower frequency is trapped by the atmosphere and we are warm. This is called the greenhouse effect. We need it.
As you go up, you have less and less 'warm blanket' to keep you warm. Actually, Nasa's had problems with too much heat with the space shuttle in orbit.
No, you won't be able to get to absolute zero. You can get get darn close. The problem is that there is background radiation, supposedly the left over from the big bang. You will still have some temperature.

As for the first part of your question, the earth's surface absorbs sun's energy more than the air, so its colder when you go up the altitude. This phenomenon is valid only upto a certain extent of the atmosphere. In the outer extremes of the atmosphere, the temperature raises again. In outer space, the side facing the sun is extremely hot while at the same time the other side is extremely cold, because you do not have any atmosphere around you.
And regarding Absolute Zero, it is possible only theoretically, and the theory says at Absolute Zero, the matter seizes to have any energy whatsoever and has no motion even at the subatomic particle level. Our scientists could achieve near Zero (withing few fractions of degree) temperature in the labs only for a very short time. Hope I am clear enough... For more information try Google the words Absolute Zero, altitude, and temperature gradient etc..

As you increase in altitude, temperature tends to decrease since the lower atmosphere is thinning out. However, there are layers in the mid or upper atmosphere where the temperature will increase again due to the sun's heat and rays being trapped in certain chemicals. If the Earth had no atmosphere, it would be much colder at night (at least -100 degF) and maybe even cooler during the day. That is why the temperature on the Moon drops below -100 degF at night and soars above 200 degF during the day.
Even space is not at absolute zero, which is 0 deg Kelvin. Astrophysicists say that space is typically 3 deg Kelvin, so absolute zero is a theoretical value at this point.

Wow... And hot air rises too, right? the heat from the sun isn't directly what you are feeling. It's the geothermal (Earth's) heat that has been absorbed that you're getting. the atmosphere is also much thinner and less able to hold heat, so up you go. As for absolute zero, it's way to hot anywhere in our atmosphere to get that cold. That is so cold that atoms can no longer move and you would fall into a pile of atoms/dust. Once in space, you really aren't gettin higher. You're just moving relative to a certain point. Depending on what point you chose, you could be moving down (relative to the moon), or up (relative to the earth). But the heat from all the stars in the universe will probably keep things warm enough to keep 0 K away

suns energy is absorbed by the ground energizing molecules in the ground creating heat, (witch is basically the transfer of kinetic energy of molecules). this also happens in the air, but air does not turn the suns light energy in to heat as well as ground does so more heat is generated close to the ground, because of this its warmer closer to the ground.
if you step out side on a sunny day and step on pavement with bare feet you can feel this.
also you go high up in the atmosphere the air is less dense and absorbs even less heat from the sun.
in space there is no air is a vacuum so there is no temperature if the sun were to shine on an object in space it wold be warmed

Nearer to the sun but with less gaz.
If you go vary far, it is surely impossible to have temperature lower than absolute zero , which is the absence of any motion

nicely i will anticipate that it may be theoretically impossible on the grounds that mass is capacity itself in E=MC^2. with a view to get rid of each and all of the capacity in a gadget will mean taking it out itself. different than that... invent a capacity sucker. Absolute 0 describes a theoretical gadget that neither emits nor absorbs capacity. by making use of international settlement, absolute 0 is defined as precisely 0 ok on the Kelvin scale, it relatively is a thermodynamic (absolute) temperature scale, and –273.c4ca4238a0b92382dcc509a6f75849b5 °C on the Celsius scale.[a million]

The ubiquitous microwave cosmic background means you cannot go lower than about 4K in outer space.
You can never, ever go below 0K.

"up" is relative... you can still go "up" and move away from the sun.
absolute zero is only acheived under strict laboratory settings, there is no way to go beyond it.
