Unit 4: Global Winds

Question 1

Coriolis effect

Answer 1

The deflection of an object’s path due to the rotation of Earth.

Question 2

Hadley Cell

Answer 2

Cycles between the equator and 30°S and 30°N. Usually hot, dry deserts.

Question 3

Polar Cell

Answer 3

Formed by air rising at 60°N and 60°S and sinking at the poles.

Question 4

Farrell Cell

Answer 4

Between Hadley and Polar cells. Determines patterns in temperature and precipitation.

Question 5

4 properties determining how air circulates in the atmosphere

Answer 5

Density, water vapor capacity, adiabatic heating or cooling, and latent heat release.

Question 6

Adiabatic heating/cooling

Answer 6

As air moves down in the atmosphere, the pressure increases and compresses the air, therefore heating it. Oppisite for cooling

Question 6

Latent heat release

Answer 6

The release of energy when water vapor condenses into liquid.

Question 6

Falling and rising air causes what?

Answer 6

Wind

Question 7

Why don’t we have one big convection current?

Answer 7

The coriolis effect

Question 7

The sun heats the equator intensely, causing what?

Answer 7

Rising warm air and falling cool air causing wind and convection currents.
