How did the Earth's Moon Form and How Has It Evolved Over Time?

The mans idle has been a subject of intrigue to scientists for centuries. The moon is a 4.53 billion year old, rocky purpose covered by craters, mountains, plains and faults. It is 384,000 kilometers away from the primer coat and revolves around it approximately each 29 days. (Hartmann & Philips, 1986) It has little more than half the concentration of the earth and no atmosphere, hydrosphere, or magnetosphere. The moon is proportionately kinda bear-sized when comp ared to the size of other moons in our solar system. Its chemical composition is largely made up of semisolid and solid rocks. cloud it does have a small amount of metallic objects, in the main iron, it does not have the same amount proportionally as the earth. The earth and moons similar physical composition has been actually influential to discovering how the moon became a satellite of the earth. (Chaisson & McMillan, 2004) sequence thither are conflicting theories on how the moon became a straggl e of the earths system most scientists agree that it was within the scratch line atomic number 6 million years of the solar systems creation. (Hartmann & Philips, 1986) The theories most ordinarily discussed for the creation of the moon are co-accretion, fission, commence and the cratering scheme. Co-accretion is the surmise that the earth and moon grew together in a satellite system.

The capture theory predicted that the moon was a foreign rocky object that was seized by the earths gravitational blow into its orbit. Fission is the theory that the moon is made up of particles of the outside layer of Earth . (Mackenzie, 1999) All common chord theori! es have recently been disproved by their inability to account for accepted physical qualities of the moon. The theory that many scientists acknowledge currently is the cratering theory. (Roach, 2003) This theory states that an object well-nigh the...
