Question 1
1 / 1 pts
When air rises at the equator it moves towards the poles. How does the Coriolis effect influence this movement?
In the Southern Hemisphere the moving air will curve to the right.
In the Northern Hemisphere the moving air will curve to the left.
The air will always curve to the moving right in both hemispheres.
In the Northern Hemisphere the moving air will curve to the right.

Which description below properly describes the atmospheric circulation cell known as a Ferrel cell?
Rising air at the equator spreads poleward and sinks at about 30 degrees latitude.
Sinking air at the equator spreads poleward and rises at about 30 degrees latitude.
Rising air at 30 degrees latitude turns poleward and sinks at about 60 degrees latitude.
Sinking air at 30 degrees latitude turns poleward and rises at about 60 degrees.

What is true of the intertropical convergence zone (ITCZ)?
It is the result of the convergence of a Hadley cell and Ferrel cell.
It coincides with areas of strong winds.
It coincides with the geographical equator.
It is subject to seasonal variations.

How does the intertropical convergence zone (ITCZ) affect monsoons?
The ITCZ moves north in the summer creating summer monsoons.
The ITCZ moves south in the summer creating dry conditions.
The ITCZ moves south in the summer creating summer monsoons.
The ITCZ moves north in the summer creating dry summer conditions.

What creates a sea breeze from the ocean to the land?
After sunset, the land cools faster than the ocean, which causes air over the ocean to rise.
After sunset, the land heats faster than the ocean, which causes air to rise over the land.
During the day the land heats faster than the ocean, which causes the air above the land to rise.
During the day, the land heats faster than the ocean, which causes the water over the land to sink.
