Question

Rivers which originate from the glaciers at high altitudes have a supply of water throughout the year. This is because ice in high mountains does not melt all at once. This is due to:

Options

• high specific heat of ice.

• low specific heat of ice.

• low specific latent heat of fusion of ice.

• high specific latent heat of fusion of ice.

Answer 1

High specific latent heat of fusion of ice.

Explanation:

Ice needs a large amount of heat to melt without a change in temperature. This high latent heat of fusion makes glacier ice melt slowly, supplying water to rivers over a long period.
