Air Pressure and Density
Rising air in a convection cell is usually associated with which type of pressure system? (High or Low?)
Low pressure
Which global convection cell is located near the equator (0 to 30 degrees latitude)?
Hadley Cell
What is the name for the apparent deflection of moving objects (like air or water) due to Earth's rotation?
Coriolis effect
What is the general term for the movement of air from high pressure to low pressure?
Wind
Sinking air in a convection cell is usually associated with which type of pressure system? (High or low?)
High Pressure
Which global convection cell is located between 30 and 60 degrees latitude?
Ferrel Cell
Which of the following is NOT a direct result of the Coriolis effect: trade winds, ocean currents, or rainfall amount?
Rainfall amount
What role does the sun play in creating winds?
The sun's uneven heating creates temperature and pressure differences that drive winds
What is the force exerted by the weight of air above a certain point called?
Air pressure
Which global convection cell is located near the poles (60 to 90 degrees latitude)?
Polar cell
In the Northern Hemisphere, in which direction does air rotate around a low-pressure system (cyclone)?
Counterclockwise
What causes differences in air pressure across Earth?
Differences in temperature (uneven heating)
What is a large-scale pattern of air movement driven by differences in temperature and pressure called?
Convection cell.
In the Southern Hemisphere, in which direction does air rotate around a cyclone?
Clockwise
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.
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.
