Winds may be named for their location or for the direction from which they blow. Which winds blow from 30° latitude in both hemispheres almost to the equator?

• easterlies

• westerlies

• trade winds

• the doldrums

Which statement describes the general pattern of winds near the equator?

• Winds are generally weak because the equator is a region of mostly low air pressure.

• Winds are generally strong because the equator is a region of mostly high air pressure.

• Winds are generally weak because the equator is a region where low and high air pressure atmospheric bands come together.

• Winds are generally strong because the equator is a region where low and high air pressure atmospheric bands come together.

Air rising and sinking in Earth’s atmosphere forms a pattern of smaller convection cells.

These convection cells create both high-pressure belts and low-pressure belts. Where in the diagram shown here are the high-pressure belts located?

• A, B, C, D

• A, C, E, G

• D, E, F, G

•      B, C, D, E, F

What role does heat play in the formation of convection currents?

• When water loses heat, it becomes denser and sinks.

• When water gains heat, it becomes denser and sinks.

• When water loses heat to cooler water, the cooler water becomes denser and sinks.

• When water gains heat, it dissolves more solids and gases, becomes denser, and sinks.

A weather report stated that rain was likely with some snow and hail also possible. Which statement is not true about rain, snow, and hail?

• They all form in clouds.

• They are all precipitation.

• They are all the same state.

• They are all made of water.

The picture shows a hurricane over the ocean.

Which statement best describes the energy flow in the formation of a hurricane?

• Energy is released as water freezes and absorbed as clouds condense.

• The sun’s energy is absorbed as water evaporates and released as it falls as rain.

• Energy is released as clouds condense and absorbed as rain falls to cause a hurricane.

• The sun’s energy is absorbed as water evaporates and released as it condenses into hurricane clouds.

A glass of ice water is shown below before and after it reaches room temperature.

Which statement explains something that occurred in the time between these two images?

• As water vapor condensed on the glass, it absorbed energy.

• The ice cubes expanded in volume as they melted into liquid water.

• The water droplets outside the glass absorbed energy as they evaporated.

• Some liquid water inside the glass sublimated into water vapor in the air.
