8.10AB - Convection & Ocean Currents, Air Masses & Fronts

Front

What are convection currents?

Back

Convection currents are the movement of fluid (liquid or gas) caused by differences in temperature and density, leading to the transfer of heat. An example is the movement of air in a circular motion in the atmosphere.

Front

Where do continental air masses form?

Back

Continental air masses form over land.

Front

What type of air mass brings cold and dry weather?

Back

Continental Polar (cP) air masses bring cold and dry weather.

Front

What causes winds?

Back

Winds are caused by differences in air pressure.

Front

Where do maritime air masses form?

Back

Maritime air masses form over water.

Front

What is the definition of an air mass?

Back

An air mass is a large body of air that has uniform temperature and humidity characteristics.

Front

What is the difference between maritime and continental air masses?

Back

Maritime air masses form over water and are typically moist, while continental air masses form over land and are usually dry.

Front

What is a front in meteorology?

Back

A front is a boundary between two different air masses, which can lead to changes in weather.

Front

What type of weather is associated with a warm front?

Back

Warm fronts typically bring gradual increases in temperature and can lead to prolonged precipitation.

Front

What type of weather is associated with a cold front?

Back

Cold fronts often bring sudden drops in temperature and can lead to thunderstorms.
