Fronts & Pressure System Quiz (Unit 4)

Draw the symbol for a Cold front. Describe the air on each side, associated weather, and direction of motion. Cold front: Cold, dense air mass displaces warm air mass, forcing the warm air up quickly and steeply.

• Cold front: Cold, dense air mass displaces warm air mass, forcing the warm air up quickly and steeply.

• Cold front: Warm, light air mass displaces cold air mass, forcing the cold air down slowly.

• Cold front: Cold, dense air mass mixes with warm air mass, creating a stable atmosphere.

• Cold front: Warm, light air mass mixes with cold air mass, creating a stable atmosphere.

Draw the symbol for a Warm front. Describe the air on each side, associated weather, and direction of motion. Warm front: Advancing warm air mass displaces retreating cold air mass and slowly, gradually slopes on top of the cold air.

• A warm front is represented by a line with semicircles pointing in the direction of movement.

• A warm front is represented by a line with triangles pointing in the direction of movement.

• A warm front is represented by a line with both semicircles and triangles.

• A warm front is represented by a dashed line.

What does the warm front symbol indicate in the diagram?

• A) Cold air moving towards warm air

• B) Warm air moving towards cold air

• C) Both air masses moving away from each other.

Fill in the blank: A stationary front occurs when two air masses meet, but neither advances into the other's territory.

• stationary front

• cold front

• warm front

• occluded front

What type of front is shown?

Evaluate responses using AI:

OFF

Fill in the blank: An occluded front occurs when a cold air mass overtakes a warm front and forces the warm air up off of the _______.

• ground

• ocean

• mountain

• tree

Define vertical and horizontal in the context of pressure systems.

• Vertical: center of the pressure system, Horizontal: surface

• Vertical: surface, Horizontal: center of the pressure system

• Vertical: top, Horizontal: bottom

• Vertical: bottom, Horizontal: top

In a High pressure system, air moves in the vertical direction:

• upward

• downward

• horizontally

• diagonally

Air moves in the vertical for a low pressure system:

• Upward

• Downward

• Horizontally

• No movement

What kind of weather is associated with each?

• High pressure systems: fair weather

• Low pressure systems: stormy weather
