Why does air pressure decrease from the troposphere to the exosphere?
a) because there are fewer air molecules as altitude increases
b) because there are more air molecules as altitude increases
c) because there are higher temperatures as altitude increases
d) because there are lower temperatures as altitude increases
What occurs within a high pressure system?
a) the formation of tornadoes
b) the formation of hurricanes
c) large clouds as air rises
d) calm weather, as air sinks
The temperature of City X has decreased by 20 degrees and clouds have formed causing rain and thunderstorms. What has most likely occurred in City X?
a) a warm front has passed
b) a cold front has passed
c) a blizzard has taken place
d) a high pressure system has stalled
How does the convection of air produce thunderstorms?
a) by causing warm air to sink and cold air to rise
b) by causing cold air to sink and warm air to rise
c) by causing both warm air and cold air to rise
d) by causing both warm air and cold air to sink
Which best explains how the Coriolis effect influences weather conditions?
a) it causes winds to rotate, forming tornadoes on Earth
b) it causes winds to rotate to the right in the Southern Hemisphere
c) it causes winds to rotate to the right in the Northern Hemisphere
d) it causes winds to follow a straight line path around Earth
Why does a sea breeze blow from the ocean towards the shore?
a) High pressure over land causes a downdraft to occur
b) the tide carries the wind to the shore as it moves back and forth
c) Conduction of heat from the warm water produces wind from the ocean
d) Air over land heats faster than air over water, which causes convection
How does the temperature of the stratosphere compare to the mesosphere?
a) It is colder than the mesosphere because the stratosphere contains the ozone layer.
b) It is warmer than the mesosphere because the stratosphere contains the ozone layer.
c) It is colder than the mesosphere because the stratosphere contains the ionosphere.

A rapidly moving cold air mass meets a slowly moving warm air mass and forms a front. What will most likely occur at this front?
a) the two air masses will mix together
b) the warm air will slide under the cold air. The cold air will rise and get warmer
c) cold air will slide under the warm air. warm air will rise and cool. clouds will form
d) the less dense warm air will sink and cool. clouds will form
