Question

A cold air mass replaces a warm air mass at a

Owarm front.
O occluded front.
O cold front.
O stationary front.

Answer 1

A cold air mass replaces a warm air mass at a cold front.

Step-by-step explanation:

A cold front is defined as the transition zone where a cold air mass is replacing a warmer air mass. Cold fronts generally move from northwest to southeast. The air behind a cold front is noticeably colder and drier than the air ahead of it. With a cold front, a colder air mass is replacing a warmer air mass. A warm front is the opposite effect in that warm air replaces cold air. There is also a stationary front, which, as the name implies, means the boundary between two air masses does not move.

Therefore, Option C is correct.
