Atmosphere

Answer 1

1. Troposphere: The lowest layer where weather occurs. Contains most of the atmosphere’s water vapor and is closest to Earth’s surface.
2. Stratosphere: Contains ozone layer (protects earth from UV rays)
3. Mesosphere: Coldest layer
4. Thermosphere: Hottest layer
5. Exosphere: Outermost layer, not enough oxygen to breathe

Question 2

Describe the processes that occur within each layer of the atmosphere

Answer 2

• Troposphere: Weather patterns, cloud formation, and precipitation.
• Stratosphere: Ozone layer absorbs UV radiation, protecting Earth.
• Mesosphere: Meteor burning (friction with air particles).
• Thermosphere: Solar radiation ionizes gas particles; where northern and southern lights occur
• Exosphere: Transition zone between Earth’s atmosphere and space.
