Question

question 5 of 15
when a cold air mass replaces a warm air mass, its called a(n) ______ front.

a. warm
b. occluded
c. stationary
d. cold

Explanation:

In meteorology (a subfield of Natural Science, specifically related to atmospheric science), a cold front is defined as the boundary where a cold air mass advances and replaces a warmer air mass. A warm front is when a warm air mass replaces a cold one, an occluded front involves three air masses, and a stationary front has little to no movement of air masses. So the correct answer is D as it matches the definition of a cold front.

Answer:

D. Cold
