Study Notes
Atmospheric Gases
- Nitrogen makes up 78% of the atmospheric gases, most common and abundant atmospheric gas
- Oxygen is the second most common atmospheric gas, making up 21% of atmospheric gases
Atmospheric Layers
- The troposphere is the lowest layer of the Earth's atmosphere, where weathering occurs
Stratosphere
- The stratosphere is the second layer of Earth's atmosphere, home of the ozone layer
- Ozone is a gas found in the stratosphere that protects earth from ultraviolet radiation from the sun
Mesosphere
- The mesosphere is the third layer of Earth's atmosphere, coldest layer and meteors burn up in this layer
Thermosphere
- The thermosphere is the fourth layer of the atmosphere, hottest layer, air very thin, energy from the sun strikes this layer first
Gravity and Air Pressure
- Gravity is the force that holds the Earth's atmosphere around Earth, creating air pressure
- Air pressure is a measure of the force with which air molecules push on Earth, caused by Earth's gravitational pull, is greatest (strongest) at the Earth's surface (sea-level) and decreases with altitude
Exosphere
- The exosphere is the outermost layer of the Earth or outer layer of the thermosphere, where communication satellites orbit
