What I learned On First Grading period in AP III

           

             AP III is all about the Geography of the world. What is the description of Geography. Geography is comes from Greek  word “Geos” and “Graphia” means description of the Earth.  I learned that only the planet Earth sustain life. Lithosphere is the terrain of the world. Then Hydrosphere of the world. In Hydrosphere 97% of the water is salt water and 3% is came from river, pond and fresh water.

             I learned the 5 theorem of the universe. One is the Big Bang Theory or Super Sonic Turbulence or the other  term Infation Theory. Fred Hoyle is the one who name it as a Big Bang theory But George Lemaitre is the owner of Inflation Theory/Big Bang Theory. Second is the Binary Star Theory by Fred Hoyle.  Fred Hoyle is assumed that formed the solar system due to the sudden  explosion  of the companion star of the sun.  And the Third is the Planetisimal Theory By George Comte de Buffon.  There are stars that ran in the sun so the small pieces of stars in galaxies are spread.
