Study Guide
Density - The amount of mass in a given volume
Radiation- Energy that moves across distances in the form of certain types of waves
Conduction-The moving of heat energy by on substance touching another
Convection- The moving of heat energy by the motion of a gas or liquid
Ozone- a molecule containing three atoms of oxygen
Particulate any tiny particle or droplet or harmful material that is mixed in with air
1. Why are we protected from most of the UV radiation from the sun?
Ozone absorbs it in the stratosphere
2. What is the correct order of atmospheric layers from Earth to exosphere?
Troposphere, stratosphere, mesosphere, thermosphere
3. Air density is
less dense at high altitudes
and more dense at low altitudes
