why does atmospheric temperature reduces with increasing altitude inspite getting closer to earth?

Answer 1

If you're incresing altitude you're getting further away from Earth. However, Temperature decreses as altitude increases because the air is thinner at higher altitudes. That means the air is less dense. Common physics will tell you as density decresases, temperature decreases. The moleucles of air aren't creating heat energy as much because they are so dispersed.

Answer 2

Space itself is VERY cold....until you get close to a star. Much of the heat we feel on the earth is heat coming up from or being reflected by the ground. As you get further and further away from the earth the air gets colder.

The air at the ground is at a higher pressure than air higher up; this is because the air at the ground is compressed by the weight of all the air above it. Air weighs quite a lot: A square column of air one meter across weighs ten tons! The air pressure decreases steadily as you go up, since there's less air pressing down from above, until you reach zero pressure, which is outer space.

If you've ever opened a container of compressed gas, like a bottle of carbon dioxide or nitrogen, you'll notice that the air coming out of it is very cold. (Even a bottle of soda does this a little; it's the cold that makes it "steam" briefly when opened.) Reducing the pressure makes most gases colder.

Now, the air in the lower atmosphere (the "troposphere") is constantly mixed by convection, which results from sunlight heating the ground. So air parcels are being constantly lifted from the ground to high altitude and back again. As a chunk of air rises, its pressure decreases, and so its temperature drops. Descending parcels are warmed as they're compressed. This is what makes the air cooler higher up: the process is called adiabatic expansion/compression

Answer 3

Logic would seem to indicate that the closer you got to the sun the hotter it should get; but it doesn't;

As you travel upwards the tempurature drops by 1.6 degrees C for every 1000 meters one climbs; you should logically get warmer, but the sun is over 93 million miles away, it is in effect stadning in London and moving 1cm closer to a bushfuire in Australia and expecting to smell smoke;

Also as you go up there are fewer particles (due to graity attracting particles closer to the surface of the earth) so each of those particles in theory has more energy than those closer to the earth (they are in most cases the 1st thing sunlight hits) but becaue there is much fewer of them heat cannot be transfered as easily as it can on the surface, close to sea level so it appears colder

As you move away from the Earth you moe closer to space, which is very cold -because of the lack of particles

Hope this helps

Answer 4

it doesn't. if the altitude increases, that means you're going further away from the earth. it also depends on where you are. Generally the closer you are to the earth, the warmer it is. and underground is the warmest, funnily enough.
