Why Hill stations are cooler,even nearer to sun than the sea level surfaces?

Question

This question was asked by my daughter when she was studying in haigher secondary. I could not answer being a science graduate and science savy person. Please give a convining reply based on the facts of scientific principles.

Answer 1

come on! its hardly a few feet closer to the sun! u do know that its a mere fraction of the distance between the sun and the earth. as we go up, the density of air reduces. this reduces the temperature. this same principle is used by water vapour in the water cycle

Answer 2

A) The earth is, on average, 150 million kilometers from the sun. Being closer on a hilltop by even a few kilometers makes virtually no difference to the incoming solar radiation.

B) The earth's atmosphere is basically transparent to visible solar radiation. The ground typically absorbs maybe 80 percent of it (this varies quite a bit from about 5% over fresh snowcover to about 90% over moist exposed soil). This heats the ground. The ground heats the air next to it through conduction and the air circulates through convection. Thus, the farther away you are from the heat source (the sun-warmed ground), the cooler it will be.

The air at the hill is blown in from surrounding areas that are "above" the surface heating, so the air is typically cooler than stations at lower elevations. In some places, however, a hillside can face south at such an angle as to render the incident sunlight more direct than surrounding "flat" surfaces. Then this hillside can actually be significantly warmer than surrounding areas at the same elevations.

Answer 3

First of all, the sun is 93,000,000 miles away. A few hundred feet closer to the sun will make no difference (besides the earth rotates). All weather and temperatures are trapped inside our atmosphere. It's like a huge bubble. This keeps all the heat the sun generates on earth, instead of dissipating into outer space, as it does on Mercury. So, distance to the sun makes no difference on weather. As you get farther away from sea level, though, temperatures do drop, because the air gets thinner, and harder to heat. Thus, it could be 80 F at the bottom of a large hill, but 75 F at the top. This is also why mountains are always much colder than their surrounding areas. Another reason hills can be cooler is that they are more exposed to cold air than lower areas like valleys. Valleys are protected from cold better.

Answer 4

hillstations are cooler because of this reasons
1)after going far from sealevel at upper side at 165 meters 1 degree celcius decrease in temp.
2)the other scientific reason is this when air at sea level became hot its go at sky and when to go at sky it also have some water drops from the sea and thus the air go up and at some stage at hight this air get steady because its warmness was lost
3)if you understand physics its a principle that if a particle has heat energy stored so it use it as a kinetic energy and its volume also increases thus its more surface came to contact of envioronment and thus its became cool

Answer 5

In the space temperature is chilly below minus degrees when it is neare to sun similarly hiher regions lesses the temperature.For evey 165 metres 1degree of celcius will come down from the sea level.

Answer 6

I'm no scientist either, but my guess would be because it gets cooler the higher the altitude, plus the wind is stronger which would cool it down as well.

YES MAN FOR OUR ENJOYMENT AND FULFILLMENT.ENJOYYYYYYYYYYYYYYY
