Earth Science Test Chapter 19

Front

What is an anticyclone?

Back

An anticyclone is a high-pressure system where winds circulate in a clockwise direction in the Northern Hemisphere, and air flows away from the center.

Front

What is the direction of wind circulation in a cyclonic system in the Northern Hemisphere?

Back

The air within a cyclonic system in the Northern Hemisphere moves in a counterclockwise direction.

Front

What is a surface wind?

Back

A surface wind is any wind that contacts the earth’s surface.

Front

What are the horse latitudes?

Back

The horse latitudes are regions of high pressure and calm winds located at about 30 degrees north and south of the equator.

Front

What are the main forms of precipitation?

Back

The main forms of precipitation include rain, snow, sleet, and hail.

Front

What is the difference between high-pressure and low-pressure systems?

Back

High-pressure systems are associated with clear skies and calm weather, while low-pressure systems are associated with clouds and precipitation.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as winds, caused by the rotation of the Earth.

Front

What is the significance of dew in weather?

Back

Dew is moisture that forms on surfaces when the temperature drops, indicating humidity levels.

Front

What is the role of the jet stream in weather patterns?

Back

The jet stream is a fast-flowing air current in the atmosphere that influences weather patterns and can affect storm development.

Front

What is the water cycle?

Back

The water cycle is the continuous process of evaporation, condensation, and precipitation that circulates water in the environment.
