Atmosphere
The surrounding air of the Earth

Layers of the atmosphere
• There are 5 layers in the atmosphere
• They are the troposphere, mesosphere, thermosphere, stratosphere, and exosphere.

Troposphere
• This is the layer that is closest to the surface of the earth
• It’s elevation ranges from 0 to 10 km

Stratosphere
• This layer sits on top of the troposphere
• It’s elevation ranges from 10 km to around 25 km
• This layer contains the ozone layer, which protects us from harmful sunlight

Mesosphere
• This layer is above the stratosphere
• It’s elevation ranges from 25 to 100 km

Thermosphere
• This is the highest layer of the atmosphere
• It’s height ranges from 100 to 400 km
• This is where most small meteorites burn up and is also the location in the atmosphere that the northern lights occur (aurora borealis)

Composition of Air
• There are many different types of gasses in the atmosphere
• They include nitrogen, oxygen, argon, carbon dioxide and other noble gasses
• The gas that is most abundant is nitrogen

Properties of the Atmosphere
• The SI temperature scale in science is the Kelvin (K) scale.
• The zero point of the Kelvin scale is absolute zero.

Temperature Inversion
• Causes: rapid cooling of land on a cold winter night.
• Effects: Can worsen air pollution problems.
• The increase in temperature with height in the atmospheric layer.

Air always wants to move from high density to low density.
•Ex. Cold air rushing out of a building door.
Wind speeds become faster at higher altitudes.

Conduction, Convection, and Radiation
• Conduction- when atoms or molecules collide.
• Convection- movement of heated materials from one place to another.
• Radiation- Through electromagnetic waves.
