Do Now

How’d you do?

Give one example of the events that occur in each temperature layer:- Troposphere: our weather, life- Stratosphere: ozone layer blocks UV

Mesosphere: meteors burn up- Thermosphere: auroras, space shuttle

Thermosphere• Name means “heat”• Altitude range: 56-600 miles• Temperature range: -120F to 3600F!• Heat source: sun (from above)• Special features: auroras, space shuttle

Mesosphere• Name means “middle”• Altitude range: 31-56 miles• Temperature range: 32F to -120F• Heat source: stratosphere (from below)• Special features: meteors burn up

Stratosphere• Name means “spreading out”• Altitude range: 6-31 miles• Temperature range: -76F to 32F• Heat source: sun (from above)• Special features: ozone layer blocks UV

Troposphere• Name means “turning”• Altitude range: 0-6 miles• Temperature range: 59F to -76F• Heat source: ground (from below)• Special features: weather, life

Minor Assessment

Assignment: Earth’s Atmosphere PowerpointYou will make a Powerpoint presentation about Earth’s atmosphere. You may use information and pictures from class, the textbook, other books, and the Internet but you MUST cite your sources (ex. title, page, web address, etc). Include text in your own words explaining any images you use. Your Powerpoint should have the following slides. Final Powerpoint is due Friday 9/13/13.

• Title slide with title, your name, period, date• Slide defining atmosphere• Slide(s) about the composition of Earth’s atmosphere

- Gases- Particulates- Energy

• Slide(s) about the properties of Earth’s atmosphere- Air has substance- Air temperature decreases as altitude increases- Air pressure decreases as altitude increases- Air density decreases as altitude increases- Protects & supports life

• Slide(s) about the structure of Earth’s atmosphere- Thermosphere- Mesosphere- Stratosphere- Troposphere
