Global Patterns of Atmospheric Movement

Front

What is the direction of air movement in relation to pressure areas?

Back

Air moves from an area of HIGH pressure to an area of LOW pressure.

Front

Why does wind blow in a curve rather than a straight line?

Back

Wind blows in a curve due to the Earth's rotation.

Front

What is the Coriolis Effect?

Back

The Coriolis Effect is the deflection of moving objects caused by the rotation of the Earth on its axis.

Front

What is the average speed of jet streams?

Back

Jet streams travel at an average speed of 110 mph.

Front

In which direction would a storm that starts in California move due to the jet stream?

Back

The storm would eventually move towards North Carolina.

Front

Define atmospheric pressure.

Back

Atmospheric pressure is the force exerted onto a surface by the weight of the air above that surface in the atmosphere of Earth (or that of another planet).

Front

What causes wind?

Back

Wind is caused by the uneven heating of the Earth's surface by the sun, leading to differences in air pressure.

Front

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

Back

The jet stream influences weather patterns by guiding storm systems and affecting temperature and precipitation.

Front

Explain how the Earth's rotation affects weather systems.

Back

The Earth's rotation causes the Coriolis Effect, which influences the direction of wind and ocean currents, affecting weather systems.

Front

What is a high-pressure system?

Back

A high-pressure system is an area where the atmospheric pressure is greater than that of surrounding areas, often associated with clear skies and calm weather.
