9.
If differences in air pressure produce winds, what can you conclude about temperature and air pressure based on the figure?
a)
As warm air rises, it creates an area of lower pressure, and cooler air flows in as wind
b)
Warm air is denser than cold air is, creating an area of high pressure the produces wind.
c)
Winds flow from areas of low pressure to areas high pressure when temperature is warmer
d)
Air pressure decreases at night because temperature is lower, producing land and sea breezes

warm air over the ocean rushes in to replace the cool air that rises over the land
c)
the heavy, cool air over the ocean rushes in to replace the warm air that rises over the land
d)
there are no clouds to block the wind coming in from the ocean
