Answer 5

Humid air is more dense that dry air

Question 6

What is the relationship between air compression and density?

Answer 6

more compression means more dense

Question 7

What is atmospheric pressure?

Answer 7

pressure at any given point on Earth exerted by the atmosphere as a consequence of gravatational force exerted on the colum of air directly above.

density of air is more than average

Question 12

What happens to air in high pressure zones?

Answer 12

Sinks

Question 13

Why does air move?

Answer 13

less dense air rises
more dense air sinks to Earth

Question 14

Which way does Earth Rotate?

Answer 14

West ot East

Question 15

How does latitude impact speed of rotation?

Answer 15

As latitude decreases, roation speed increases

Question 16

What is the coriolis effect?

Answer 16

Force acting on a body in motion due to the rotation of the Earth causing deflection.

Question 17

How does the coriolis effect impact the hemispheres?

Answer 17

Earth Rotates to the **right **in the North hemisphere
and Left in the Southern hemispere

Question 18

What is deflection in relation to the coriolis effect?

Answer 18

amounts of deflected win is dependent on **speed **and location

Question 19

Which winds deviate the most?

Answer 19

polar, and fast winds

Question 20

Which wind deviates the least?

Answer 20

tropical, and slow winds

Question 21

How are winds named?

Answer 21

By the direction they are moving

Question 22

What are rising air areas?

Answer 22

Doldrums

Question 23

What are high pressure areas?

Answer 23

horse latitudes

Question 24

What is the ITCZ?

Answer 24

Intrtropical convergence zone

Question 25

What happens at the ITCZ

Answer 25

area of rising air and high atmospheric pressure near equator Where wind systems of Northern and Southern Hemispheres converge

Question 26

What happens to land and ocean in summer months?

Answer 26

land is warmer than the ocean low pressures develop global high pressure belt

Question 27

What happens to air in the summer?

Answer 27

moves away and deflects right.

Question 28

What happens to land and ocean during winter months?

Answer 28

land is colder than the ocean. high pressure zones separate low pressure zones over water

Question 29

How does air move during winter months

Answer 29

Pulls in and deflects right

Question 30

How does air move when theres counterclockwise roation at low pressure?

Answer 30

Moves in and deflects right

Question 31

What are modern scale circulations?

Answer 31

rising air over land replaced by warm moist air Carried on southwest winds from Indian ocean Offshore airflow causes condensation

Question 32

What is rain shadow?

Answer 32

Mountains deflect wind upward:cools riding on windward side of mountain; heavy precipitation Descending air on leeward side: low precipitation

Question 33

What is an example of a small scale circulation pattern?

Answer 33

land sea breezes

Question 34

tropical oceans when surface water temperature exceeds 28 celcius

Question 36

What is a storm surge?

Answer 36

**elevation of sea surface** beneath the center of a storm caused by l**ow intense pressure**

Question 37

What is a storm tide?

Answer 37

**max. sea surface elevation **when **storm surge** collides with **high tide**
