Unit 5 Retake Test

Wind patterns are partly created from warm air rising and cold, denser air coming to replace it. The movement of the warm and cold air help to create wind. Which most likely provides the energy required to cause the differences in air temperature?

• The Sun

• The Moon

• The rotation of Earth

• The tilt of Earth's axis

• Humidity levels

• Wind speed

What is causing the movement inside the cell?

• The warm, high-pressure air heated by the Sun near the poles is moving toward the equator along the surface, while cool, low-pressure air cooled at the equator moves toward the poles in the upper atmosphere.

• The warm, low-pressure air heated by the Sun near the equator is moving toward the poles along the surface, while high-pressure air cooled at the poles moves toward the equator in the upper atmosphere.

• The Sun is radiating energy to the top of the atmosphere, increasing the air's density and causing it to sink and be replaced by the cooler, lighter air.

• The air is convecting as the air near Earth's surface pulls the cold out of the ground, rises, and is replaced by warmer, denser air.

Which of the following does NOT contribute to global wind patterns?

• The tilt of Earth on its axis, causing uneven solar heating

• The spin of Earth on its axis, causing rotational movement

• The uneven distribution of people between continents, causing uneven heat convection

• The uneven distribution of land between hemispheres, causing uneven heat conduction

What does the model most likely represent?

• The convection of ocean currents caused by Earth's rotation on its axis

• The conduction of ocean currents caused by water flowing into cooler depths as the sea floor spreads

• The conduction of ocean currents caused by water heating from volcanic eruptions

• The convection of ocean currents caused by the amount of radiant energy absorbed by the Sun

Heat energy causes there to be differences in temperature and pressure on Earth's surface. When water in Earth's oceans and atmosphere expands and rises, it —

• destroys heat by reversing winds and ocean currents.

• reflects heat by increasing winds and ocean currents.

• generates heat by reducing winds and ocean currents.

• moves heat by creating winds and ocean currents.

• Volcanoes

• Weather

• Sunspots

• Earthquakes

The Midwestern United States is home to "Tornado Alley," a portion of Texas, Oklahoma, Kansas, and Nebraska commonly plagued with powerful and plentiful tornadoes. Tornado Alley is located at a point where the jet stream drives cool, dry, high-pressure air masses from the deserts and mountains of the West toward the East Coast. With which type of air mass do these high-pressure fronts collide to create so many tornadoes?

• Moist, warm, low-pressure air masses from the Gulf of Mexico

• Dry, warm, high-pressure air masses from the Atlantic Ocean

• Moist, cool, low-pressure air masses from Canada

• Dry, cool, high-pressure air masses from Alaska

• Rain is likely to continue in the Great Lakes area.

• Los Angeles will soon feel a drop in temperature.

• Temperatures in Dallas are likely to rise soon.

Thunderstorms develop as a result of which process in ocean areas?

• Rising warm air creating low pressure cells

• Rising warm air creating high pressure cells

• Falling air temperatures creating low pressure cells

• Falling air temperatures creating high pressure cells
