Cold air mass X moves over warm air mass Y, and evaporation occurs.
Cold air mass X moves over warm air mass Y, and evaporation occurs.

Warm air mass Y moves over cold air mass X, and condensation occurs.
Warm air mass Y moves over cold air mass X, and condensation occurs.

Cold air mass X mixes with warm air mass Y, and the overall temperature increases.
Cold air mass X mixes with warm air mass Y, and the overall temperature increases.

Warm air mass Y mixes with cold air mass X, and the overall temperature decreases.

Answer 1

The correct response is:

**Warm air mass Y moves over cold air mass X, and condensation occurs.**

This scenario is conducive to winter storm formation, as the warm, moist air from air mass Y rises over the colder, denser air from air mass X. As the warm air rises, it cools and condenses, which can lead to precipitation and storm development.
