8th Grade Common Assessment #1

If differences in air pressure produce winds, what can you conclude about temperature and air pressure based on the figure?

• As warm air rises, it creates an area of lower pressure, and cooler air flows in as wind
• Warm air is denser than cold air is, creating an area of high pressure the produces wind.
• Winds flow from areas of low pressure to areas high pressure when temperature is warmer
• Air pressure decreases at night because temperature is lower, producing land and sea breezes

At the seashore late in the afternoon on a hot day, a person often feels a strong breeze coming from the ocean because...

• the pounding waves generate air currents
• warm air over the ocean rushes in to replace the cool air that rises over the land
• the heavy, cool air over the ocean rushes in to replace the warm air that rises over the land
• there are no clouds to block the wind coming in from the ocean

The main reason that we have currents in the ocean and air is

• the sun heats the air and ocean evenly everywhere
• the heat inside the earth heats the ocean and the ocean heats the air
• the sun cannot heat both the air and water, so one must heat the other
• the sun heats air and water more at the equator because it receives more direct sunlight
