Answer 1

Frost is experienced in mountainous regions

Answer 2

"Answer: Mountainous regions

When the object’s surface becomes cooler than the dew formation point of water vapor, tiny ice particles form on the surface of the object and these ice particles are called frost particles.

Such cold conditions exist generally on the mountainous areas and so frost is usually experienced in these regions, especially during the nights."
