Air Pressure and Fronts

What is the effect of high air pressure on weather?

• High air pressure generally leads to clear skies and calm weather.

• High air pressure causes storms and heavy rainfall.

• High air pressure results in increased humidity and cloud formation.

• High air pressure has no significant effect on weather patterns.

What is air pressure?

• The force exerted by the weight of air above a surface.

• The amount of air in a given volume.

• The temperature of the air in the atmosphere.

• The speed at which air moves in the environment.

How does cold air compare to warm air in terms of moisture capacity?

• Cold air holds more moisture than warm air.

• Cold air holds less moisture than warm air.

• Cold air and warm air hold the same amount of moisture.

• Cold air can hold moisture only when it is heated.

What is the main difference between a cold front and a warm front?

• A cold front occurs when warm air pushes into a region of cold air, while a warm front occurs when cold air moves over warm air.

• A cold front occurs when cold air pushes into a region of warm air, while a warm front occurs when warm air moves over cold air.

• A cold front occurs when cold air and warm air meet without moving, while a warm front occurs when warm air rises above cold air.

• A cold front occurs when warm air is trapped between two cold air masses, while a warm front occurs when cold air is trapped between two warm air masses.

What type of weather is typically associated with a warm front?

• Heavy rainfall and thunderstorms

• Gradual warming and light to moderate precipitation

• Cold temperatures and snow

• Strong winds and clear skies

What type of front is represented by a red line with semicircles?

• Cold front

• Warm front

• Stationary front

• Occluded front

What symbol represents an occluded front on a weather map?

• A blue line with triangles

• A red line with semicircles

• A purple line with alternating triangles and semicircles

• A green dashed line

What is a weather front?

• A type of storm that occurs in winter.

• The boundary between two different air masses, which can lead to changes in weather.

• A measurement of temperature changes in the atmosphere.

• A phenomenon that only occurs in tropical regions.

What is the effect of low air pressure on weather?

• Low air pressure is often associated with cloudy skies and precipitation.

• Low air pressure leads to clear skies and dry conditions.

• Low air pressure causes high temperatures and sunny weather.

• Low air pressure results in strong winds and storms.

What is an occluded front?

• A front that forms when two warm air masses collide and rise.

• A front that occurs when a cold front overtakes a warm front, lifting the warm air off the ground.

• A boundary between two cold air masses that causes heavy precipitation.

• A stationary front that remains in place for an extended period.
