because air pressure decreases as altitude increases. As air rises, the pressure decreases. It is the lower pressure at higher altitude that causes temperature to be colder on the top of a mountain compared to sea level.
They are not as near the sun.
the sun's rays strike the water at a angle at the poles APEX
The sun is very far away, it takes light form the Sun 8 minutes to reach the Earth. At this scale the difference in height between the top of a mountain and the beach is insignificant, both places receive the same amount of light/heat form the Sun. What makes the mountain top cold is vertical variation in temperature caused by the earths atmosphere. As you go up form sea level, the air cools by about one degree Centigrade for every 300 feet you go up. Thus as you are surrounded by colder air, it is colder on the top of a mountain - (or looking at it another way, the mountain pokes up into a region of colder air). Look at the link I will place below for more information on air temperature.
no it isn't cuz Pluto is further away from the sun!
Yes planets get colder when further away from the Sun.
They are not as near the sun.
The air is thinner
The sun is about 93 million miles away. Going up a mountain so that you're a mile closer does nothing at all. The temperature is colder because air pressure at those elevations is lower, and these two variables are directly related.
Things get hotter because of the sun, and things get colder because of the snow
The top of a mountain is closer to the sun than the land around during the day it, but given that the sun is more than 90 million miles away, that difference is negligible. The higher you go up in the atmosphere, the colder it gets. This is because the air at high altitudes is less compressed than the air at low altitudes. When a gas is decompressed, it cools.
Colder compared to what? It is colder in the winter than in the summer because the northern hemisphere is tilted away from the sun in the winter. It is colder in Vermont compared to southern states because it is farther from the equator, and therefore receives lesss heat from the sun
when the sun shines the denser air over the valley of a mountain gets warmed up.These warmed air rises up and reaches the mountain tops.As it reaches the mountain tops it expands adiabatically because the pressure at mountain tos is low
Because the Earth revolves around the sun. The further we are from the sun, the colder it gets.
Mountaintops are colder than the lowlands because the Sun heats the Earth from the ground up. The Sun's radiation travels through the atmosphere to the ground, where Earth absorbs the heat then emits it back out. So, temperatures near the Earth's surface is generally the warmest.
Because it is further away from the sun
the sun's rays strike the water at a angle at the poles APEX
It's caused by its rotation Think of it when the Earth rotates it faces the sun which makes it warmer. Because the Sun gives off heat When it is in winter it should be colder because the Sun is not facing us.
