How the Moon Was Formed Essay

Until recently there was many debates on how the moon, our nearest planetary neighbor was formed. Well we believe that at some point in Earth's early history, a rogue planet, larger than Mars, struck the Earth in a great, glancing blow. Instantly, most of the rogue body and a sizable chunk of Earth were vaporized. The cloud rose to above 13,700 miles altitude, where it condensed into innumerable solid particles that orbited the Earth as they aggregated into ever larger moonlets, which eventually combined to form the moon. Studies also show that by measuring the ages of lunar rocks, we know that the moon is about 4.6 billion years old, or about the same age as Earth. So this seems to be a pretty accurate theory as to how the moon was …show more content…
This is because the moon's gravitational pull causes two bulges of water on the Earth's oceans, one where ocean waters face the moon and the pull is strongest and one where ocean waters face away from the moon and the pull is weakest. Both bulges cause high tides. These are high tides. As the Earth rotates, the bulges move around it, one always facing the moon, the other directly opposite. The combined forces of gravity, the Earth's rotation, and other factors usually cause two high tides and two low tides each day. The ocean tides are magnified by other effects: frictional coupling of water to Earth's rotation through the ocean floors, the inertia of water's movement, ocean basins that get shallower near land and oscillations between different ocean basins. The gravitational attraction of the Sun on the Earth's oceans is almost half that of the Moon, and their gravitational interplay is responsible for spring and neap tides. There has also been some speculation as to why the moon does not have any water. Well because the moon has such small mass and low gravity, it makes the ability of water flow impossible so that means there is no weathering or erosion. However, the moon is bombarded by water-laden comets and meteoroids. Most of this water is lost to space, but some is trapped in permanently shadowed areas near both poles of the
