Only a front is the movement of a weather system.


b)

An air mass is a large body of air that takes on the characteristics of the area over which it forms, while a front is a narrow region separating two air masses of different densities.


c)

A front takes on the characteristics of the area over which it forms, while an air mass is a narrow region separating two different densities areas.

Answer 1

Option (B)

Step-by-step explanation:

The front refers to the transition zone that lies between two types of air masses which are of distinguishable density. It extends both vertically and horizontally. The fronts are divided into 4 types, namely-

(1) Warm front

(2) Cold front

(3) Stationary front

(4) Occluded front.

These fronts are often shown in the weather map by using patterns with different colors, where each indicates a type of front.

On the other hand, air masses refer to the body of air mass that is characterized by having a certain composition of density, temperature and moisture content. It varies from place to place.

Thus, the correct answer is option (B).
