Earth’s Lower Atmosphere & Planetary Wind Belt

What is the main factor that causes weather to occur in the troposphere?

• The presence of carbon dioxide

• The presence of almost all the water vapor in our atmosphere

• The ozone layer absorbing ultraviolet radiation

• The gravitational pull of the Moon

What happens to the cold, dry Polar cell air at the poles?

• It rises and moves toward the equator

• It stays stationary and does not move

• It descends at the poles

• It mixes with the Hadley cell at the equator

The Hadley cell is located at the:

• Poles

• 30° latitude

• Equator

• 60° latitude

Why does warm air over the equator rise?

• It is less dense than cold air

• It is pushed up by the winds from the poles

• The Coriolis effect forces it upward

• High pressure at the equator lifts it

What forms the Hadley cell?

• The meeting of air masses at 60° latitude

• The convergence of the Northeast and Southeast trade winds at the equator

• The cooling of air at the poles

• The deflection of wind due to the Coriolis effect

What causes planetary cells with different wind belts?

• The Sun’s direct and indirect rays creating unequal heating

• The presence of water vapor in the atmosphere

• The gravitational pull of the Moon

• The interaction of ocean currents and air pressure

At which latitude does descending air create high pressure and a dry climate?

• 0° (equator)

• 15° N and S

• 30° N and S

• 60° N and S

The Coriolis effect is caused by:

• The Earth’s rotation

• Unequal heating of the Earth

• The gravitational pull of the Sun

• The movement of ocean currents

The Planetary Wind Belts Model indicates that at 43° N latitude, winds move:

• Toward the northeast

• Directly southward

• In a circular pattern

• Directly westward

In the Northern Hemisphere, how do winds from the equator move as they approach the poles?

• They are deflected to the left

• They move in a straight path

• They are deflected to the right

• They spiral downward
