Question

what occurs in an updraft?
cool air from mountains causes high winds.
warm air from the surface rises.
warm air high in the atmosphere sinks.
cool air from the surface spins in a circle.

Explanation:

An updraft is the upward movement of air. Warm air is less dense than cool air, so warm air from the Earth's surface (where it's heated) rises, which is what happens in an updraft. The first option is about cool air from mountains causing winds (not an updraft's main process). The third option describes sinking warm air (opposite of updraft). The fourth option describes a spinning cool air (like a vortex, not an updraft).

Answer:

B. Warm air from the surface rises.
