Important Instructions for Taking Quiz

There are two kinds of questions those with circles in front of the answers and those with squares in front of the answers. The ones with circles have only one answer. The ones with squares can have more than one answer but might only have one answer. Lets say a question has 2 right answers and you check the correct boxes but you also check two boxes that are the wrong answer. You will get a score of zero on the question even though 2 of the answers were correct.

The earth spins from

West to East
East to West

Hot air flowing because of a pressure difference between the equator and the North Pole will flow in what direction?

Toward the North
Toward the South
Toward the North East
Toward the South West

The polar vortex spins in what region of the atmosphere?

The Troposphere
The Stratosphere
The Thermosphere
The Exosphere

Why do temperature differences lead to pressure differences?

Because hot air is lighter than cold air so hot air presses up and cold air presses down
Because expansion of hot air presses against the ground

Why does temperature change faster over the Artic than over the equator?

Because the heat reaching the equator is spread out over a much larger area.
Because ice reflects heat a lot more than water does so if ice melts there should be more water and more heat absorbed
