Define snow field and snow line.what are the factors which affect the snow line ?
Answers
Answer:
A snow field, snowfield or neve is an accumulation of permanent snow and ice, typically found above the snow line, normally in mountainous and glacial terrain
The snow line on a mountain is the boundary beyond which there is permanent snow. It is about 3,500 metres above sea level. The snow line's location depends on conditions such as elevation, latitude, proximity to the sea, climate, wind direction, exposure, and the steepness of the slope.
Answer:
snow line, altitude above which or latitude beyond which snow does not melt in summer (usually called the permanent snow line), or, in winter, the line to which snow extends at a given point in time. Factors affecting the location of the snow line are the quantity of snowfall, the steepness of the slope on which snow rests, the exposure of an area to the sun and prevailing winds, the type and velocity of the winds, and the presence or absence of large bodies of water. The level of the snow line is much lower in winter than in summer. It is also affected by distance from the equator, along which it is found at an altitude of c.3 mi (5 km); in polar regions it is at sea level.
