Multiple Choice

What is wind?

• How hot or cold a place is.

• The state of the atmosphere.

• The direction of water.

• Air movement caused by differences in air pressure.

Multiple Choice

• east wind

• west wind

• north wind

• south wind

Multiple Choice

What is humidity?

• How hot or cold a place is.

• The amount of water vapor in the air.

• Air movement

• The state of the atmosphere

Multiple Choice

What is circulation?

• Amount of water vapor in the air

• The state of the atmosphere.

• The direction of wind

• The large-scale movement of air, it redistributes heat on Earth

Multiple Choice

As a hiker moves up a mountain, the air pressure

• increases.

• decreases.

• stays the same

• increases and then decreases

Multiple Choice

How does the size of the column of air pushing down at sea level relate to the air pressure reading of a barometer?

• The column of air is tall, so the barometer indicates a relatively high air pressure.

• The column of air is short, so the barometer indicates a relatively high air pressure.

• The column of air is tall, so the barometer indicates a relatively low air pressure.

• The column of air is short, so the barometer indicates a relatively low air pressure.

Multiple Choice

How does high air pressure affect a mercury barometer?

• Air pressure presses down more on the surface of the mercury and forces the column of mercury higher.

• Air pressure presses less on the surface of the mercury, so the column of mercury falls lower.

• Air pressure presses down more on the surface of the mercury and forces the column of mercury lower.

• Air pressure presses less on the surface of the mercury, so the column of mercury rises.
