The mass of air surrounding a planet

The pressure exerted by the atmosphere on all objects within it

An instrument used to measure atmospheric pressure

The lower layer of the earth's atmosphere, which exists from the ground level to roughly 80 kilometers (50 miles) above sea level

The upper layer of the earth's atmosphere, which exists higher than roughly 80 kilometers (50 miles) above sea level

The region of the atmosphere that extends from ground lever to roughly 11 kilometers (7 miles) above sea level

The region of the atmosphere that spans altitudes of roughly 11 kilometers to 48 kilometers (30 miles)

The region of the atmosphere that spans altitudes of roughly 48 kilometers to 80 kilometers (50 miles)

Narrow bands of high-speed winds that circle the earth, blowing from west to east

Energy that is transferred as a consequence of temperature differences

A measure of energy of random motion in a substance's molecules

The region of the atmosphere between altitudes of roughly 80 kilometers and 460 kilometers

The region of the atmosphere above altitude of roughly 460 kilometers

The region of the atmosphere between the altitudes of roughly 65 kilometers and 330 kilometers, where the gases are ionized
