Atmosphere Layers & Energy Transfer & Wind

Heat energy from Earth's surface transfers to the air by

• convection

• conduction

• radiation

• the Coriolis Effect

Heat energy in the air moves around the globe by

• convection

• conduction

• radiation

• the Coriolis Effect

Where does Earth get its energy from?

• Radiation from the Sun

• Convection in the Earth's Core

• Conduction from Outer Space

• Friction from Moving Winds

Students watched hot water with red dye rise to the top of a tank and cold water, that was dyed blue, sink to the bottom. The water created a circular motion. What type of heat flow was demonstrated by the circular movement of water?

• convection

• conduction

• radiation

• friction

Which statement must happen in order for conduction to occur between objects?

• The objects must be exposed to electromagnetic waves.

• The objects must circulate around.

• The objects must contain liquid.

• The objects must touch.

The transfer of heat is responsible for many of the events that occur on Earth. Which of the following events is most directly caused by radiation?

• the movement of Earth's mantle

• the movement of ocean currents

• the warming of Earth's surface

• the circulation of air

If both the land and the ocean receive the same amount of energy from the Sun, what is most likely true about the temperatures of the land and ocean?

• the ocean has a bigger range of daily temperature

• the land heats up more quickly than the ocean

• the ocean heats up more quickly than the land

• the land and ocean temperatures are the same

Which of the following describes the part the Sun plays on a windy day at the beach?

• The Sun reflects off the water, making the air above the water unstable and more likely to move.

• The Sun heats the land quickly and as its warm air rises, cool air comes in from the water.

• The Sun causes waves to be larger by directing solar energy into the water.

• The Sun calms the wind throughout the afternoon as everything warms up.

Which of the following statements gives the best definition of air pressure?

• There is air in underwater bubbles, but the bubbles are not air pressure.

• Air pressure is the force exerted by the weight of the air.

• Changes in air pressure can cause winds to blow.

• Sound moves through the air but is not related to air pressure.

When sailing ships were used for transatlantic voyages, captains often avoided the equator.

Which of the following would be the most likely scientific reason for them to avoid the equator?

• The increased temperature of the water at the equator may produce other effects, but not jets of steam.

• The directions of the currents near the equator are stable.

• There are no high winds in the doldrums.

• There are no prevailing winds at the equator.
