Question 8

During the land breeze, what starts moving the cooler air out and warmer air in?

Accepted Answer

convection

Answer

conduction

Answer

radiation

Question 9

Air at the poles is colder and denser so it_______________.

Accepted Answer

sinks

Answer

rises

Answer

circulates

Answer

stagnates

Question 10

Air is warmer and less dense at the equator because the equator receives more____________________.

Accepted Answer

solar radiation

Answer

wind

Answer

air pressure

Answer

condensation

Question 11

Use the diagram to determine which statement is correct.

Accepted Answer

High pressure air at location 2 is taking the place of the low pressure air at location 3.

Answer

The air at location 3 is more dense than the air at location 6.

Answer

The air at location 2 is rushing in to take the place of the colder air at location 3.

Answer

Spirally

Answer

Circularly

Answer

Kinetically

Question 14

What creates the air pressure difference between the equator and the poles?

Accepted Answer

The amount of direct sunlight each area receives

Answer

The length of the seasons

Answer

The shape of the earth

Answer

the duration of the solar year

Question 15

When heat rises cools then sinks

Accepted Answer

convection current

Answer

high pressure

Answer

low pressure

Answer

stratospheric pressure

Question 16

If differences in air pressure produce winds, what can you conclude about temperature and air pressure based on the figure?

Accepted Answer

As warm air rises, it creates an area of lower pressure, and cooler air flows in as wind

Answer

Warm air is denser than cold air is, creating an area of high pressure the produces wind.

Answer

Winds flow from areas of low pressure to areas high pressure when temperature is warmer

Answer

Air pressure decreases at night because temperature is lower, producing land and sea breezes

Question 17

Answer

the pounding waves generate air currents

Answer

warm air over the ocean rushes in to replace the cool air that rises over the land

Answer

there are no clouds to block the wind coming in from the ocean

Question 19
