The snow on the mountains does NOT melt all at once when it is heated by the sun because:
Ait has a low specific heat capacity
Bit becomes very hard
Cit reflects most of the heat from the sun
Dit has a high latent heat of fusion
Correct answer
D. it has a high latent heat of fusion
Explanation
At mountain, there is very large amount of snow i.e. m is very very high. And for melts of ice, latent heat of fusion is required. Latent heat of fusion = mass×Lf And since very very large mass is present so very high amount of heat is required which can’t be delivered by sun at once.
