Unequal heating of Earth's surface helps to cause wind by creating differences in air pressure. Which diagram best shows this process?
A diagram showing warm air rising and cool air sinking, creating a convection current.
A diagram showing equal heating of Earth's surface with no air movement.
A diagram showing only the sun and the Earth with no air movement.
A diagram showing wind blowing from warm areas to other warm areas.
Each layer of Earth’s atmosphere has unique characteristics. Choose the THREE descriptions that match the troposphere best.
This layer is farthest from Earth’s surface.
The layer closest to Earth’s surface.
Supersonic jets fly here because of the calm air.
The water cycle takes place here.
All weather is contained here.
At higher elevations, water boils at a lower temperature. Which factor is most responsible for this change?
Increased air pressure at higher elevations
Decreased air pressure at higher elevations
Higher humidity at higher elevations
Greater sunlight at higher elevations
The ozone layer protects Earth by:
Blocking harmful ultraviolet (UV) radiation from the sun.
Increasing the amount of oxygen in the atmosphere.
Absorbing carbon dioxide from the air.
Reflecting visible light back into space.
The ionosphere is used for radio communication because it:
absorbs radio waves completely
reflects radio waves back to Earth
blocks all radio signals
generates radio waves
