Earth's Atmosphere

atmosphere (atm)

• a unit of pressure based on the average pressure of air at sea level; 1 atm = 101,325 Pa
• A form of oxygen that has three oxygen atoms in each molecule instead of the usual two.
• 0-17 km above Earth's surface, site of weather, organisms, contains most atmospheric water vapor. (temperature decreases with increasing altitude, pressure decreases)

Ozone

• Energy that is radiated or transmitted in the form of rays or waves or particles.
• A form of oxygen that has three oxygen atoms in each molecule instead of the usual two.
• pollution that comes from many sources rather than from a single, specific site

water vapor

• Form of heat transfer where heat energy is directly transferred between molecules through molecular collisions or direct contact.
• An instrument that measures atmospheric pressure
• water in the form of a gas

air pressure

• Energy that is radiated or transmitted in the form of rays or waves or particles.
• Form of heat transfer where heat energy is directly transferred between molecules through molecular collisions or direct contact.
• The measure of the force with which air molecules push on a surface

barometer

• Heat energy
• Wispy, feathery clouds made of ice crystals that form at high levels.
• An instrument that measures atmospheric pressure

altitude

• Elevation above sea level
• narrow bands of high-velocity winds at the top of the troposphere; typically there are two in each hemisphere
• The transfer of thermal energy by the circulation or movement of a liquid or gas

Troposphere

• narrow bands of high-velocity winds at the top of the troposphere; typically there are two in each hemisphere
• 0-17 km above Earth's surface, site of weather, organisms, contains most atmospheric water vapor. (temperature decreases with increasing altitude, pressure decreases)
• The uppermost layer of the atmosphere, in which temperature increases as altitude increases

Stratosphere

• An atmospheric condition formed through a combination of weather conditions and pollution, especially from motor vehicle emissions.
• 2nd layer of atmosphere; extends from 10 to 30 miles up; location of ozone layer; absorbs 95% of Ultraviolet radiation; temperature increases with altitude increase.
• Elevation above sea level

Mesosphere

• Fluffy, white clouds, usually with flat bottoms, that look like rounded piles of cotton.
• The layer of Earth's atmosphere immediately above the stratosphere
• a scale that ranks levels of ozone and other air pollutants

Thermosphere

• The uppermost layer of the atmosphere, in which temperature increases as altitude increases
• An instrument that measures atmospheric pressure
• Elevation above sea level
