Air expands at higher temperatures.

Warm air moves toward the coastline from inland areas.

The land heats up faster than water, creating a sea breeze.

The water heats up faster than the land, creating a land breeze.

When cool air rises, nearby air that’s warmer rushes in to fill the empty space left behind. The rushing air is what we call wind.

Cool air produces low air pressure and warm air produces high air pressure. Warm air wants to rise. When warm air rises, cool air will move in and replace the warm air, causing wind.

During the day, the air above the land heats faster than air over water. This warm air over the land expands and rises, and the cooler air, which is heavier, takes its place, creating wind.

Cool equatorial air rises higher into the atmosphere and migrates toward the poles. At the same time, warmer, denser air moves over Earth’s surface toward the Equator to replace the cooled air, creating wind.

the ozone layer does not allow meteorites to hit Earth’s surface

ten percent of oxygen producing organisms live within the ozone layer

without this barrier in place, all of the Sun’s radiation would reach Earth

this protective barrier prevents the frigid air found in space from cooling the planet
