​Layers of the Atmosphere

​- We live in the Troposphere

​- Ozone layer is between Troposphere and Stratosphere

​- Stratosphere Weather balloons

​- Mesosphere becomes cold enough to freeze water into clouds

​- Thermosphere is the hottest layer of the atmosphere

Multiple Choice

• Southern Hemisphere

• Northern Hemisphere

Multiple Choice

Seasons are caused by ....

• Earths tilt on its axis and the relative position of the Sun

Review key points

• Weather vs. Climate

• Nitrogen and oxygen dominate the volume of atmospheric gasses

• Atmosphere is divided into 4 layers

• The Atmosphere thins as you travel away from Earth

• Seasons are caused by the tilt of Earth's axis and relative positions of the Sun

• Water Vapor is the source of all clouds and precipitation
