Using the information in the map, how does the air temperature of City 2 compare to the air temperature of City 1? Why?

• City 2 is colder than City 1 because it has a cold current passing by.

• City 1 is warmer than City 2 because it has a warm current passing by.

• City 1 is colder than City 2 because it has a cold current passing by.

• City 2 is warmer than City 1 because it has a warm current passing by

Harold is using what he knows about cause-and-effect relationships to write a paper explaining cloud shape. How could he describe cause and effect in his paper?

• There is only one cause for cloud shape, because each effect has one cause.

• There can be more than one cause for the effect of cloud shape.

• It is impossible to determine which factors cause cloud shape and which factors are the effects of cloud shape.

• Some things, like cloud shape, do not have a cause because they just happen.

What are prevailing winds?

• winds that move in one direction and are strong enough to move ocean currents.

• Ocean currents that move in one direction and are around enough to affect winds.

• winds that move in every direction and AREN'T strong enough to move ocean currents

The equator is at _____ degrees latitude.

• 0

• 10

• 50

• 90

Answer explanation

The equator is the line that represents 0 degrees latitude.

City 1 and City 2 are the same distance from the equator and they are both near the ocean. Use the information on the map to answer these questions: How does the air temperature of City 2 compare to the air temperature of City 1? Why?

The air at City 2 is...

• The same as City 1. Even though the ocean water at each location is a different temperature, the same amount of energy is transferred to the air at both locations.

• The same as City 1. They are both near moving ocean water, so the same amount of energy is transferred to the air at both locations.

• Colder than City 1. At City 2, energy is transferred from the air to the ocean. At City 1, energy is transferred from the ocean to the air.

• Colder than City 1. At City 2, only a little energy is transferred from the air to the ocean. At City 1, a lot of energy is transferred from the ocean to the air.

Answer explanation

The current near City 2 is a cool current and is bringing less energy because it starts near the equator.

Locations that are farther from the equator have colder air temperatures because...

• less energy is transferred directly to the air

• more energy is transferred from the surface to the air

• they have more sunlight

• less energy is transferred from the sun to the surface and then to the air

True or False: There is only one cause for each effect.

• True

• False

Fairview and Washington are the same distance from the equator, and both cities are near the ocean. The air temperature in Fairview is colder than the air temperature in Washington. What causes the air temperature in these places to be different?

• There is no way to figure this out.

• Who knows.

• The ocean water is much cooler than the air of Washington, so the ocean transfers energy to the air. This makes the air cooler.

• The ocean water is much warmer than the air of Washington, so the ocean transfers energy to the air. This makes the air warmer.
