Is a snowline the same elevation everywhere in the world?

Question

the snow part of the land.

Answer 1

No, due to differences in the amount of solar energy recieved by different areas of the earth as a result of the way in which earth orbits the sun - the equator receives a lot of solar radiation (and hence heat) at a high angle to the earth's surface, whereas the poles receive much less. So the equator is hotter than the poles! There is a gradient in the elevation of the snowline - from very high elevations near the equator to very low near the poles - hence in the tropics, you don't get snow at elevations which you WOULD in colder regions... and at the poles the snow line is way down - Antarctica is covered in snow and ice all year, so is above the snow line - but it's an ordinary continent, not a mountain or something!

Answer 2

nope,

there is ozon hole and reflection of the sun ray by the land and sea

Answer 3

no because of reflection
