Air moves in large, circular patterns called

• pressure belts.

• convection currents

• convection cells.

• trade winds.

In the Northern Hemisphere, winds traveling north appear to curve to the east because of the

• trade winds.

• convection currents.

• Coriolis effect.

• polar easterlies.

Global winds that blow from west to east are called

• polar easterlies.

• westerlies.

• mountain breezes.

• trade winds.

Global winds that blow northeast from 30° north latitude and southeast from 30° south latitude are called

• northerlies.

• trade winds.

• polar easterlies.

• global easterlies.

Narrow belts of winds that can reach 400 km/h are called

• jet currents.

• jet streams.

• convection currents.

• convection streams.

Local winds are produced by

• global winds.

• global geographic features.

• local farms and ranches.

• local geographic features.

Mountain and valley breezes are caused by

• differences in temperature and elevation.

• similarities in temperature and elevation.

• the same temperature at all elevations.

• high temperatures at all elevations.
