right
Explanation: As a result of the Coriolis Effect, air is deflected to the right in the Northern Hemisphere.
100
Cool air is _____ dense than warm air. Therefore, cool air _____ to the surface, while warm air _____ upwards.
Cool air is more dense than warm air. Therefore, cool air sinks to the surface, while warm air rises upwards.
Explanation: Cool air and warm air have different densities. This density difference is what causes air to circulate in convection cells.
100
Sea breeze occurs during the ____, while land breeze occurs during the _____.
Sea breeze occurs during the day, while land breeze occurs during the night.

Monsoon rains do not benefit the people or industries in those regions.
True or False
False
Explanation: Although they can be devastating, heavy monsoon rains are needed to support drinking water supply and agriculture industries in certain regions.
200
In the Southern Hemisphere, air is deflected to the...
left
Explanation: As a result of the Coriolis Effect, air is deflected to the left in the Southern Hemisphere.
200
The following latitudes are associated with dry conditions:
____ degrees N/S and ____ degrees N/S
30 degrees N/S and 90 degrees N/S
Explanation: Looking at our ESRT diagram, we see that air is diverging at these latitudes. Therefore, cool and dry conditions exist in these regions.
200
One of the most famous examples of a monsoon system is in _____, a densely populated country located in Asia.
India
Explanation: India and its surrounding countries have a monsoon system. We saw the impacts of their rainy season at the beginning of class today!
200
The wet and dry belts change locations over the course of the year.
True or False.
True
Explanation: Look at Page 14 of your ESRT! The locations shift somewhat with the changing latitude of the Sun's vertical ray.
300
The Coriolis Effect is caused by...
the rotation of the Earth
Explanation: The Earth's rotation causes objects to move in an apparent curved path.
300
Looking at Page 14 of the ESRT, what climate conditions exist where winds converge?
warm and wet
Explanation: Convergence refers to air coming together and rising upwards. This is associated with the "wet" areas on our diagram.
300
When air flows from the land towards the sea, this circulation is referred to as a _____ breeze.
land breeze
Explanation: The terms "sea breeze" and "land breeze" refer to where the air originates. Therefore, air in a land breeze originates from the land; it is goes from the land to the sea.
300
Higher temperature gradients between the land and sea will decrease wind speed in a sea breeze or land breeze.
True or False
False
Explanation: Higher temperature gradients will increase wind speed. A greater difference in temperature means a greater difference in air density.
400
In one 24-hour rotation, objects near the _______ travel less distance than objects near the Equator.
Poles
Explanation: Objects near the poles are moving slower because they have less distance to cover during the 24-rotation cycle.
400
The convection cell that circulates between the Equator and 30 degrees N/S is called a __________ cell.
Hadley cell
400
During monsoon rainy season, _____ air over the land rises as ____ air over the ocean sinks. This circulation of air is a large-scale, seasonal version of a ____ breeze.
During monsoon rainy season, warm air over the land rises as cool air over the ocean sinks. This circulation of air is a large-scale, seasonal version of a sea breeze.
Explanation: This air circulation draws lots of moisture from the ocean and causes the intense rainy season associated with monsoons.

There is a monsoon system in North America.
True or False
True
