Question

1 why does a warm air mass generally contain more moisture than a cold air mass? 2. an ____________ front is formed when a warm air mass is \sandwiched\ between two cold air masses. 3. the boundaries between air masses of different characteristics are called __________ or __________. 4. when a cold air mass replaces a warmer air mass, the leading edge of this cold air mass is called a ____________ front.

Explanation:

1. Warmer air can hold more water - vapor because the higher temperature gives water - molecules more energy to remain in the gaseous state.
2. An occluded front is formed when a warm air mass is between two cold air masses.
3. The boundaries between air - masses of different characteristics are called fronts or transition zones.
4. When a cold air mass replaces a warmer air mass, the leading edge of the cold air mass is called a cold front.

Answer:

1. Warmer air can hold more water - vapor due to higher energy of water - molecules.
2. Occluded
3. Fronts; transition zones
4. Cold
