Winds, Air Pressure, Heat Transfer Test

Local winds differ from global winds because they

• are caused by unequal heating within a small area.

• are caused by differences in cloud cover.

• are due to unequal rainfall.

• are not influenced by air masses.

Global winds generally

• are not influenced by the heating of Earth's surface.

• are unpredictable.

• change directions from day to day.

• blow from specific directions over long distances.

What layer of the atmosphere helps protects us from meteors?

• Troposphere

• Stratosphere

• Mesosphere

• Ionosphere

The energy from the sun is transferred by

• conduction

• induction

• convection

• radiation

Heat transfer between two substances that are in contact/touching is called

• conduction

• thermal energy

• convection

• radiation

Convection takes place because

• warm air is more dense than light air.

• warm and cold air have the same density.

• cold air is less dense than warm air.

• cold air is more dense than warm air.

• light emission

• convection

• radiation

Winds are caused by differences in

• precipitation

• humidity

• air pressure

• turbulence
