Answer 1

The ice sheets from the north and south poles and the icecaps on the mountains, get converted into water vapour through the process of sublimation.

Explanation:

• Sublimation is the process where a substance changes directly from a solid state to a gaseous state without passing through the liquid phase.
• At the poles and on mountain icecaps, ice can directly turn into water vapor under specific conditions of low pressure and temperature, which is sublimation.
