Exploring the Composition and Thinness of Earth's Atmosphere

Discover what the atmosphere is made of, why it's so thin, and the role of gases in anaerobic respiration. Anaerobes, which use chemicals like hydrogen and sulfur for energy production, play a crucial part in the carbon, nitrogen, and sulfur cycles. Learn how gases behave and the impact of gravity on our atmosphere's composition.

  1. Atmosphere: what is it made of? By: Kaylee, Tamir, and Peter

  2. Why is the atmosphere so thin? • Gas particles in the atmosphere move around freely. They expand or become compressed. Due to earth's gravity, all of the earth's atmosphere is drawn towards the surface. It gradually becomes thinner as you leave earth's surface.

  3. The Rules of Gases in Anaerobic Respiration • While aerobes use oxygen for respiration, anaerobes use chemicals such as hydrogen and sulfur to harvest energy. These are generally less efficient for energy production than oxygen is. The carbon, nitrogen, and sulfur cycles depend heavily on anaerobic processes. • Obligate anaerobes cannot live in the presence of oxygen
