Unit 3 Lesson 2 Review

Front

What is the Tropic of Capricorn?

Back

The Tropic of Capricorn is the line of latitude located at 23.5 degrees south of the Equator, marking the southernmost point where the sun can be directly overhead.

Front

What is the Antarctic Circle?

Back

The Antarctic Circle is the line of latitude located at 66.5 degrees south of the Equator, marking the area where, during the summer solstice, the sun does not set and during the winter solstice, the sun does not rise.

Front

What causes cool air to sink?

Back

Cool air sinks because of gravity, which pulls the denser, cooler air down towards the Earth's surface.

Front

What is the Hadley cell?

Back

The Hadley cell is a large-scale atmospheric circulation pattern that circulates air between the equator and 30 degrees latitude, contributing to trade winds.

Front

What are trade winds?

Back

Trade winds are steady winds that blow from east to west near the equator, resulting from the Earth's rotation and the Hadley cell circulation.

Front

What is the Equator?

Back

The Equator is the line of latitude at 0 degrees, dividing the Earth into the Northern and Southern Hemispheres.

Front

What are polar easterlies?

Back

Polar easterlies are cold winds that blow from the east near the poles, typically found between 60 degrees latitude and the poles.

Front

What are westerlies?

Back

Westerlies are winds that blow from the west to the east in the mid-latitudes, typically found between 30 and 60 degrees latitude.

Front

What is the significance of latitude lines?

Back

Latitude lines are important for determining climate zones, time zones, and navigation on Earth.

Front

What happens at the Tropic of Cancer?

Back

The Tropic of Cancer is located at 23.5 degrees north of the Equator, marking the northernmost point where the sun can be directly overhead.
