TEST - Winds, Fronts, Ocean Currents

Wind is caused by

• differences in humidity and dew point

• differences in air temperature and air pressure

• differences in continental deflection

• height above sea level

Differences in air temperature and air pressure are caused by

• topography and elevation

• relative humidity

• evaporation, sublimation, and condensation

• uneven heating of the Earth's surface

How does wind form?

• cool air sinks/high pressure forms and then warm air rushes in to fill the space

• warm air rises/low pressure forms and then cool air rushes in to fill the space

• air moves around the poles causing wind to form

• ocean water evaporates which causes condensation and then wind forms

The global movement of air occurs in convection cells. In general, how does air move?

• areas of high pressure to higher pressure

• areas of low pressure to lower pressure

• areas of low pressure to high pressure

• areas of high pressure to low pressure

The Coriolis effect is the curving path of a moving object. How does this influence wind?

• It causes winds to move in straight paths.

• It changes the height at which wind travels.

• It causes the air to move.

• It changes the direction of the wind.

Land

• heats and cools faster than water

• heats and cools slower than water

• heats and cools at the same rate as water

• heats and cools only if it's near water

Both global winds and local winds

• are prevailing winds

• are based on their altitude

• move in straight paths

• are caused by uneven heating of the Earth's surface

What causes warm air to rise?

• The fact that it is less dense than cold air.

• The fact that it weighs more than cold air.

• The fact that it has higher pressure than cold air.

• The fact that it's more dense than cold air.

Which term best describes how the earth's atmosphere is heated?

• spirally

• unevenly

• circularly

• kinetically

What can you conclude about prevailing winds from their name?

• They blow from west to east.

• They blow all of the time.

• The air they contain is very warm.

• The air they contain is very cool.
