Why dont mountain glaciers melt away in the summer?

Question

thats the Question

Answer 1

They do melt to a certain extent, providing cold mountain streams below them.

They are too extensive in size for a complete summer season to melt all of them.  

What they lose in the summer is for a great part replaced with winter moisture, which freezes on the glacier.

Answer 2

well its because once it gets hot enough the atom in the glaciers start to move around more and more freely. once they get loose enough they change the physical form of the water. So if the atoms in the glacier are very close together then the water is frozen, as they get looser they turn from water to gas. once the water evaporates the atoms are prety much flying all ever the place. there is one last stage that there is on matter, that is called plasma. the atoms are going at super high speeds and when they crash agings each other ther then they release high amounts of energy. this kind of matter does not exits naturally on earth but it does on stars, we can create it artificially here on earth. we create it by accelerating particles on a electromagnetic chamber, we do that because only magnetic Fields can hold temperatures tha high.  well that is why glaciers melt away, sorry i kind of went off tipoc. LOL   hope this helped.

Answer 3

because the temperature

Answer 4

The altitude makes is colder so they do not melt. If the summer is long enough they will eventually melt but the altitide is natures refrigertor.

Answer 5

becasue its cold and nevr gets warm.

Answer 6

the high elevations of the mountains stay pretty cold, even in the summer.

Plus, there is so much ice in the glacier that it doesn't have time to melt. Even on warm days, the amount of water that melts off is insignificant compared to the size of the glacier.

Do this, put an ice cube in a glass of tap water. It melts, but not instantly, it takes a few minutes. Now when you are dealing with an ice cube that is miles long, and thousands of feet wide, it takes longer than the entire summer to melt it, and when winter comes around again, more water freezes to it so that the glacier never disappears.

Answer 7

They do, but water drains to the rivers and glaciers shift slowly.  They are receding but in winter they replenish again.

Answer 8

Because it's freaking cold up there

Answer 9

because there are thousands of miles thick and wide. it would take many years to melt them all.

also it is incredibly cold up there. trust me i rode a helicopter up to one in alaska and we walked around on it for about 30 minutes and it was FREEZING!!

Answer 10

because its still god d**n freezing

Answer 11

because it's always cold up there.

Answer 12

it's cold and they don't get enough sun, and that which they DO get, is mostly reflected because of the snow and ice, not absorbed.

It does get warm enough to melt some of the top layers, but not for long enough and not warm enough, at least historically. The following year of snow is more than enough to replenish what melted.

However, the whole thing with global warming and the glacier recession is that the longer warm season and the warmer days and the reduced amount of snow is causing more melting than replenishment.

In addition, the meltwater runs off and erodes and melts even more of the ice, which erodes and melts more and more, so it's a compound effect.

I've been snowboarding on a glacier and it's amazing.

Answer 13

Because with altitude temperature reduces.The air around is chilling and no way to make it warm.To make it warm Sun rays need to fall on earth material and up there very little earth material is present.It needs a valley to absorb Sun rays and make the air warm.
