Air Masses & Fronts

What kind of front is characterized by two air masses meeting and stopping?

• Cold front

• Warm front

• Stationary front

• Occluded front

What happens when a cold front is approaching?

• Warm air rises, cools, and causes rain and thunderstorms.

• Cold air sinks and creates clear skies.

• Warm air stays at the surface and leads to dry weather.

• Cold air mixes with warm air, causing fog.

What is the symbol for a warm front?

• A blue line with triangles pointing in the direction of the front.

• A red line with semicircles pointing in the direction of the front.

• A green dashed line with arrows pointing in both directions.

• A yellow line with squares pointing in the direction of the front.

What type of front is represented by alternating triangles and semicircles?

• A warm front

• A cold front

• An occluded front

• A stationary front

What kind of front occurs when a warm air mass gets caught between two cold air masses?

• Cold front

• Warm front

• Occluded front

• Stationary front

What is the symbol for a cold front?

• A red line with semicircles pointing in the direction of the front.

• A blue line with triangles pointing in the direction of the front.

• A green dashed line with arrows pointing in both directions.

• A yellow line with squares pointing in the direction of the front.

What is the main characteristic of a stationary front?

• It moves rapidly, causing sudden weather changes.

• It does not move significantly, leading to prolonged weather conditions.

• It is characterized by strong winds and thunderstorms.

• It separates warm air from cold air, leading to clear skies.

What is an occluded front?

• A front where a warm air mass is caught between two cold air masses.

• A front where two warm air masses collide.

• A front that occurs when cold air pushes under warm air.

• A front that forms when two cold air masses meet.

What happens to air pressure when a cold front passes?

• Air pressure typically rises.

• Air pressure typically falls.

• Air pressure remains constant.

• Air pressure fluctuates wildly.

What is a warm front?

• A warm air mass meets a colder air mass and slowly rises over it.

• A cold air mass meets a warmer air mass and pushes it upwards.

• Two warm air masses collide and create thunderstorms.

• A warm air mass remains stationary and does not interact with colder air.
