  3. Composition • 71% hydrogen • 27.1% helium • less than 2% of all other elements • Oxygen, Carbon, Nitrogen, Silicon, Magnesium, Neon, Iron and Sulfur • The mass of the sun is over 99.8% of the mass of the entire known solar system http://hyperphysics.phy-astr.gsu.edu/hbase/solar/sun.html#c1

  4. Distance • From the sun to the Earth is 149,000,000 km. • This equals 1 AU (Astronomical Unit). http://hyperphysics.phy-astr.gsu.edu/hbase/solar/sun.html#c1

  5. Energy • Almost all life on earth is maintained by energy from the sun. • Plants synthesize sugar molecules from carbon dioxide and water. • This energy can then be transferred to other organisms and utilized throughout a food web. http://www.project2061.org/publications/sfaa/online/chap5.his insufficient, tm

  6. The amount of life possible that any environment can sustain is limited to the basic resources of energy, minerals, and water. • When the inflow of resources desertification and depletion of minerals occurs. http://www.project2061.org/publications/sfaa/online/chap5.his insufficient, tm
