EARTH SCIENCE lesson 2 LIFE ON EARTH

• The habitable zone, also called Goldilocks zone, provides just the right amount of heat and provides Earth with the capacity to maintain water in its liquid form.
• Earth is at the residential planet located in the Goldilocks zone or habitable zone
• Earth is the third planet from the sun and 5th largest planet in the solar system.
• Earth has unique physical and chemical characteristics compared to other neighboring planets
• Earth is the only habitable planet or planet known in the solar system that can support life.
• Earth Temperature Influences how quickly atoms and molecules move.
• Earth temperature Allows liquid water to exist on Earth's surface which is favorable to life.
• Water dissolves and transports chemical in and out pf the cell.
• The existence of water in three phases is very essential to earth's diverse ecosystem.
• The atmosphere traps heat, Shields the surface from harmful radiation, and provides chemicals needed for life, such as nitrogen and carbon dioxide.
• The atmosphere regulates the balance of water, oxygen and carbon dioxide.
• Energy from the sun; Light or chemical energy is used by Organism to run their life processes such as the process of photosynthesis used by producers like plants
• Nutrients is used to build and maintain an Organisms body
• A planet requires A rapidly rotating magnetic field to protect it from flavors from nearby stars and from harmful radiation

  water (explains temperature)

  Too cold: freeze - Ice } Right amount of heat

  Too heat: evaporate - Gas } Right amount of heat

  
  

  2. The capacity to maintain liquid form: H2O
• Water is a Universal Solvent
• The temperature of the water should be in the middle to maintain its liquid form
• In the gaseous sphere, 78% of the atmosphere is nitrogen, 21% is oxygen, and 1% are other gases.
• Carbon dioxide traps heat in the atmosphere and is a greenhouse gas
• Monosaccharide is the scientific name of simple sugar/Glucose
• C6H1206 - glucose
