Question

comparing types of fronts
match each front with its description.
occluded front
cold front
warm front
stationary front
when a cold air mass slides under a warm air mass
when a warm air mass slides over a cold air mass
when a cold air mass and a warm air mass meet and do not move
when two cold fronts force a warm front up and block it from the surface

Explanation:

To solve this, we recall the definitions of each front:

• Occluded front: Occurs when two cold fronts force a warm front up and block it from the surface.
• Cold front: Happens when a cold air mass slides under a warm air mass (cold air is denser, so it pushes up the warm air).
• Warm front: Occurs when a warm air mass slides over a cold air mass (warm air is less dense, so it rises over the cold air).
• Stationary front: Forms when a cold air mass and a warm air mass meet and do not move (neither is strong enough to replace the other).

Now we match:

• Occluded front → when two cold fronts force a warm front up and block it from the surface
• Cold front → when a cold air mass slides under a warm air mass
• Warm front → when a warm air mass slides over a cold air mass
• Stationary front → when a cold air mass and a warm air mass meet and do not move

Answer:

• occluded front: when two cold fronts force a warm front up and block it from the surface
• cold front: when a cold air mass slides under a warm air mass
• warm front: when a warm air mass slides over a cold air mass
• stationary front: when a cold air mass and a warm air mass meet and do not move
