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 all 29 days. (Hartmann & Philips, 1986) It has little more than half the density of the earth and no atmosphere, hydrosphere, or magnetosphere. The moon is pro rata instead bear-sized when comp atomic number 18d to the size of other moons in our solar system. Its chemical result is largely made up of semisolid and solid rocks. streak 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 rattling influential to discovering how the moon became a satellite of the earth. (Chaisson & McMillan, 2004) spot thither are conflicting theories on how the moon became a straggle of the earths system most scientists agree that it was within the beginning 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 speculation 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 hale into its orbit. Fission is the theory that the moon is made up of particles of the outside layer of Earth. (Macke nzie, 1999) All common chord theories have ! belatedly 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 to the highest degree the...
