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

The mans idle has been a defeat of intrigue to scientists for centuries. The moon on is a 4.53 billion year old, uncut purpose covered by craters, mountains, plains and faults. It is 384,000 kilometers away from the primer rise and revolves around it approximately either 29 days. (Hartmann & Philips, 1986) It has diminutive more than half the engrossment of the human race and no atmosphere, hydrosphere, or magnetosphere. The moon is pro rata sooner bear-sized when comp ard to the size of other moons in our solar system.

(Hartmann & Philips, 1986) The theories most normally discussed for the creation of the moon are co-accretion, fission, commence and the cratering scheme. Co-accretion is the opening that the earth and moon grew together in a satellite system.

The fascinate theory predicted that the moon was a foreign rocky object that was seized by the earths gravitational draw up into its orbit. Fission is the theory that the moon is made up of particles of the satellite layer of Earth. (Mackenzie, 1999) All ballpark chord theories have latterly been disproved by their inability to account statement for accepted physical qualities of the moon. The theory that many scientists acknowledge soon is the cratering theory. (Roach, 2003) This theory states that an object close to the...
