Earth has a low air pressure zone at the equator because

• air is cold and sinks toward the surface of Earth there

• air is cold and moves away from the surface of the Earth there

• air is warm and moves away from the surface of the Earth there

• air is warm and moves toward from the surface of the Earth there

• air is cold and sinks toward the surface of Earth there

• air is cold and moves away from the Earth there

• air is warm and moves away from the surface of the Earth there

• air is warm and sinks toward the surface of Earth there

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
