  3. Did you get it right? • What is Earth’s atmosphere made of? • Gases (air) • Particulates • Energy (ex. Heat, radiation, etc) Do Now

  4. What is the atmosphere? • Look up and write down the definition for atmosphere from two different sources. • Textbook: • Science dictionary: • Webster’s dictionary: • Computer dictionary: • Online: Defining key words McDougall textbook, p. A11

  5. What is the atmosphere? • Envelope of gases surrounding Earth • Layer of gases that surrounds Earth • Mixture of gases that surround Earth Defining key words McDougall textbook, p. A11

  6. Most of the materials in Earth’s atmosphere are gases • 78% Nitrogen • 21% Oxygen • 1% (Argon, CO2, and other gases) • Up to 4% water vapor • Essential for life Composition of Earth’s Atmosphere McDougall textbook, p. A11

  7. Most of the materials in Earth’s atmosphere are gases • 78% Nitrogen • 21% Oxygen • 1% (Argon, CO2, and other gases) • Up to 4% water vapor • Essential for life It also contains solid & liquid particles (particulates) • Dust • Sea salt • Fungal Spores • Viruses & bacteria • Pollen • Water droplets Composition of Earth’s Atmosphere http://www.dustcollectorsource.com/hepafiltration.html

  8. 1. Living things use gases in the air: • oxygen, nitrogen, argon, carbon dioxide, & water vapor 2. The atmosphere keeps Earth warm. • Transports energy to different regions of the planet (radiation, conduction & convection). 3. The atmosphere protects & supports life. 4. Supplies materials that your body uses. The Composition makes life on Earth Possible.

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 • Slide(s) about the properties of Earth’s atmosphere • Slide(s) about the structure of Earth’s atmosphere Major Assessment
