200

Which of the following is NOT a direct result of the Coriolis effect: trade winds, ocean currents, or rainfall amount?

Rainfall amount

200

What role does the sun play in creating winds?

The sun's uneven heating creates temperature and pressure differences that drive winds

300

Which global convection cell is located near the poles (60 to 90 degrees latitude)?

Polar cell

300

In the Northern Hemisphere, in which direction does air rotate around a low-pressure system (cyclone)?

400

What causes differences in air pressure across Earth?

Differences in temperature (uneven heating)

400

What is a large-scale pattern of air movement driven by differences in temperature and pressure called?

Convection cell.

400

In the Southern Hemisphere, in which direction does air rotate around a cyclone?

Clockwise

500

As a parcel of air is heated near Earth's surface, what happens to its volume and density?

It's volume expands and its density decreases.

500

What causes convection cells to form in the atmosphere?

Uneven heating of Earth's surface by the sun.

Where on Earth is the Coriolis effect strongest? For double points, also tell me where on Earth it is the weakest.

Strongest at the poles, weakest at the equator.
