Question

Snow line is the level on mountains above which snow never_____________.
A) Melts throughout the year
B) Freezes throughout the year
C) Both
D) None

Answer 1

Hint: The snow line is a sporadic line situated along the ground surface where the collection of snowfall approaches removal. This line changes significantly in height and relies upon a few impacts. On windward slants and those confronting the evening sun, the snow line might be just about as much as a kilometre higher than on inverse inclines.

Complete answer:
Now let us analyze the given options:
Option A) Snow line can be characterized as a height above which snow presence is seen consistently. Snow is never liquefied at this reach. At or close to the equator, it is commonly at around 4,500 meters. In the Himalayas, the extremely durable snow line can be just about as high as 5,700 meters. Hence, This option is correct
Option B) When the heat from the sun is absorbed by the snow on mountains its temperature starts to rise to a less negative value and later approaches its melting point. And later with the heat energy that is absorbed by the snow makes it change its state from solid to liquid. Thus, there cannot be a constant freezing point. Hence, This option is incorrect
Option C) Scientifically it is impossible to naturally freeze and melt simultaneously at the same point. Hence this option is incorrect.
Option D) This option is incorrect because one of the options given above is already correct.

Thus, the correct option is (A). The snow line is the level on mountains above which snow never melts throughout the year.

Note: Over bigger regions, summer temperatures and the measure of snowfall decide the situation of the snow line. Where temperatures are low, as close to the shafts, the snow line is very low in rising; where temperatures are high, as close to the Equator, the snow line is exceptionally high.
