Information about Snow Line
This article is about the geographical feature. For the boundary in a protoplanetary disk, see Frost line (astrophysics).
The snow line is the point above which, or poleward of which, snow and ice cover the ground throughout the year.
The interplay of altitude and latitude affect the precise placement of the snow line at a particular location. At or near the equator, it is typically situated at approximately 4,500 meters (or about 15,000 feet) above sea level. As one moves towards the Tropic of Cancer and Tropic of Capricorn, the parameter at first increases: in the Himalayas the permanent snow line can be as high as 5,700 metres (18,700 feet). Beyond the Tropics the snow line becomes progressively lower as the latitude increases, falling all the way to sea level itself near the poles.
In addition, the relative location of a mountain to the nearest coastline can be a factor in how high the snow line would be; a peak near a coast — especially the west coast — of a continent might have a lower snow line than one of the same height and at the same latitude situated in a landmass interior, because the average summer temperature of the surrounding lowlands would be warmer in the latter spot than in the former, thus making a higher altitude necessary to keep the snow from melting in the summer.

In astronomy or planetary physics, the frost line, also known as the snow line, refers to a particular distance in the solar nebula from the central protosun where it is cool enough for hydrogen compounds such as water, ammonia, and methane to condense into solid ice grains.

Altitude is the elevation of an object from a known level or datum (plural: data). Common data are mean sea level and the surface of the WGS-84 geoid, used by GPS.

equator is an imaginary line on the Earth's surface equidistant from the North Pole and South Pole. It thus divides the Earth into a Northern Hemisphere and a Southern Hemisphere. The equators of other planets and astronomical bodies are defined analogously.
