higher average wind speeds than the ocean side
B
less rain than the ocean side
C
more rain than the ocean side
D
more hurricanes than the ocean side

A
Coriolis effect.
B
convection currents.
C
trade winds.
D
polar easterlies.
7) Which of these MOST likely causes winds to blow on Earth?
A
Earth spins quickly, causing air to blow around.
B
Ocean waves push air onto the shore and across Earth's surface.
C
The gravity of Earth and the Moon push and pull the air.
D
Warm air rises and cool air falls toward Earth's surface.
8) When moist air from the ocean moves toward a mountain slope the climate is MOST likely has
A
dryer weather on the ocean side
B
more frequent rainfall on the ocean side
C
high winds and clear skies on the ocean side
D
extreme cold and low humidity on the ocean side
9) Which of these BEST explains the cause of convection currents in Earth’s atmosphere?
A
The light and heat reflected from the Moon varies as the Moon chnages phases.
B
Sunlight is more concentrated in some places on Earth than others.
C
Glaciers moving away from the poles cool Earth unevenly..
D
Heat from Earth’s core heats the land only at the equator.
10) Convection is the transfer of energy
A
as heat through a material.
B
to the atmosphere.
C
as electromagnetic waves.
D
by the circulation of gases or liquids.
11) Most solar energy that reaches Earth’s atmosphere is
A
scattered by clouds.
B
absorbed by Earth's surface.
C
absorbed by clouds, ozone, and gasses.

flooding
B
sea breeze
C
deep water currents

A
because warm air is less dense than cold air
B
because cold air is less dense than warm air
