  • Earth is termed as a "planet of life" where matter and energy continue to flow
  • The main source of energy is the sun
  • Most of the earth's surface is about 75% covered with water
  • Adult humans is about 60% water by weight
  • Atmosphere - gases that surround the planet
  • Biosphere - living organisms on earth
  • Hydrosphere - all bodies of water on earth
  • Lithosphere - solid part of the earth, including crust and upper mantle
  • Cryosphere - frozen parts of the hydrosphere (ice)
  • Geosphere - rocks and soil below the lithosphere
  • Earth's temperature range from about -88°C to 58°C
  • The planet's atmosphere is approximately 21% oxygen , a gas which produced mostly by plants
  • Temperature 

    This will influence how quickly atoms and molecules move . When its warmer they move faster , when its cooler they move slower
  • Most livung things can survive in temperature between -15°C and 115°C
  • Only earth has the right chemical materials like liquid water that could support life
  • The atmosphere has a layer called the ozone layer , which blocks harmful radiation from the sun
  • Earth's atmosphere is about 100 miles thick .
  • Earth is in the goldilock zone . A reguon with the right temperature to sustain life
  • Without the green house effect the earth would be frozen
  • By the help of plate tectonics , it slowly releasing heat from inside the earth through volcanic eruption and new ocean floor to keep the earth surface from getting too hot
  • The goldilock zone are also known as the habitable zone is an area around a star where it's not too hot and not too cold the condition here are just right or for liquid water to exist under making it potentially suitable for life as we know it
  • The temperature range that good for life is usually between freezing 0° c or 32° f and fairly warm up to 50° c or 122° f
  • Living things  need oxygen in the atmosphere to survive
  • Organisms who get nutrients from the food they eat, this nutrients are used for energy to fuel their activities , growth , and repair for their bodies
