Presentation Transcript

  1. What is the Sun composed of? • Super heated gases (plasma)

  2. What holds the Earth and the otherplanets in orbit???? the Sun’s gravitational pull

  3. What determines the Sun’s influence on all of the objects in our solar system? Distance

  4. What kind of star is the Sun? • Yellow dwarf

  5. WHAT drives the Earth’s seasons, climate and ocean currents • The sun

  6. How does the wind and ocean regulate the temperature of the Earth? • Oceans store the Sun’s energy, thereby creating wind.

  7. What is an astronomical unit? • 149.60 million km – the distance from the Earth to the Sun

  8. The Earth is surrounded by a thin buffer of air called the atmosphere which is held around the Earth by the force of gravity.

  9. What does the atmosphere shield us from? • Harmful radiation and meteorites

  10. How does the atmosphere allow life to exist on the Earth? • regulates the temperature, • a protective shield, • allows evaporating water to form clouds and produce rain • provides us with air to breathe

  11. What role does the Sun play in a food chain? • It is the first source of energy to producers

  12. What is the atmosphere made up of? • ¾ nitrogen and ¼ oxygen

  13. Most important component necessary for life to exist on Earth? • Water

  14. What are the three states of water on Earth? Give examples of how they exist. • Liquid in oceans, lakes, rain, etc. • solid in glaciers and frozen bodies of water • gaseous in water vapor

  15. How does water vapor regulate Earth’s temperature? • Evaporating water prevents the Earth’s surface from getting too hot, like sweat on the body. • It allows clouds, rain and snow to form

  16. How does the length and time of light received from the Sun affect the possibility of plant life on planets? • Allows time for photosynthesis to occur

  17. The proximity( closeness) of the Sun to Earth determines the amount of heat and light the Earth will receive.

  18. Necessary for life to exist on Earth….. • The availability of liquid water for use by living organisms and the presence of water vapor necessary to the formation of weather and climate.

  19. What is necessary for life to exist on Earth: A non-poisonous atmosphere composed of gases that enable organisms to survive.

  20. What role does the Sun play in a food chain? It is the first source of energy to producers
