Equinox
On what calendar day is the Equinox? What season in the Northern Hemisphere begins on this day?
Equinox

Spring
The northernmost point on the earth to receive the direct rays of the sun - latitude 23 1/2 degrees N.

(Check all that apply)
All but b
Does the earth's atmosphere gets thinner or thicker as elevation increases?

What effect does this have on temperature? Why?
The air gets thinner.

Temperatures decrease, because thinner air retains less heat.
Movement of air across the surface of the earth, caused by the sun heating up the earth's atmosphere and surface unevenly
Wind
Global winds that blow in a fairly constant pattern - determined by latitude and affected by the earth's movement
Prevailing winds
The name which describes how the earth's winds blow clockwise in the N Hemisphere and counter-clockwise in the S Hemisphere
Coriolis Effect
Prevailing winds of the low latitudes
Trade winds
Prevailing winds of the mid latitudes
Westerlies
Prevailing winds of the high latitudes
Polar easterlies
A narrow, windless band at the Equator is called what?

You have this same windless band just north of the Tropic of Cancer and just south of the Tropic of Capricorn. Here it is called what? Why?
the Doldrums

the Horse latitudes - because horses were thrown overboard to lighten the load so the ships could continue sailing
Cold and warm streams of water moving through the oceans
currents
Periodic change in the pattern of ocean currents and water temperatures in the Mid-Pacific region.
El Nino
The side of the mountain range facing the wind
Windward side
The side of the mountain range NOT facing the wind
Leeward side
Which landform has more stable temperatures, water or land?
Water
Warm ocean air blows onto land and meets a mountain range. Describe what happens to the air temperatures.
The air is pushed up the mountain
The rising air cools, producing precipitation on the windward side
As the precipitation is released, the air becomes dryer on the leeward side

Dry areas, and even deserts, develop on the leeward side of the mountains
The dry air on the leeward side of a mountain range produces an effect called what?
Rain shadow
