As warm air rises on the ocean sid of a mountain what are the likely weather conditions on the opposite side?
a) less rain than the ocean side
b) more rain than the ocean side
c) more hurricanes than the ocean side
d) higher average wind speeds than the ocean side
In the Northern Hemisphere, winds traveling north appear to curve to the east because of the
a) trade winds.
b) convection currents.
c) Coriolis effect.
d) polar easterlies.
Which of these MOST likely causes winds to blow on Earth?
a) Earth spins quickly, causing air to blow around.
b) The gravity of Earth and the Moon push and pull the air.
c) Warm air rises and cool air falls toward Earth's surface.
d) Ocean waves push air onto the shore and across Earth's surface.
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
Which of these BEST explains the cause of convection currents in Earth’s atmosphere?
a) Heat from Earth’s core heats the land only at the equator.
b) Glaciers moving away from the poles cool Earth unevenly..
c) Sunlight is more concentrated in some places on Earth than others.
d) The light and heat reflected from the Moon varies as the Moon chnages phases.
Convection is the transfer of energy
a) by the circulation of gases or liquids.
b) as electromagnetic waves.
c) as heat through a material.
d) to the atmosphere.
