YouTube 2 The Moon


How the Moon was Born

In this clip titled "How the Moon was born" it shows the process of the moon being created by earth having volcano’s and earthquakes erupting. Everyday asteroids rained down from the Heavens. The footage in this clip is astonishing. They show volcanic eruptions and comets. So then one plant THEA hit the Earth it collided and caused massive debris. Earth survived THEA was destroyed but from the aftermath. Earth was born & so was the Moon. Although this video may not have actual footage it is really cool to see how others try to explain the evolution of the moon.

One of the earliest questions ever was, how was the mood created? There are 4 theories impact, coaccertion, fission, and capture. I will explain each..


  • IMPACT : One theory is that it was formed from the Earth's crust, following the impact of a large (Mars-sized) asteroid. A long string of rocky fragments were blown out from the Earth in the form of a trail, which coalesced into the Moon. Supporting this, the Earth has a large iron core but the Moon does not : the Earth's iron would have already sunken into the core by the time the giant impact happened.
  • COACCRETION : Another theory, advocated by Edward Roche, is known as coaccretion. It proposes the concurrent information of both the Earth and the Moon from clouds of space material. As a result the new Moon gets spun by the Earth's gravity field and starts to circle the Earth. The fact is that all smaller solar bodies appear to be irregularly shaped, but larger ones are nearly spherical.
  • FISSION : The fission theory states that the Moon long ago split off from a fast-rotating Earth, like mud flung from a spinning bicycle wheel. The present Pacific Ocean basin is the most popular site for the part of the Earth from which the Moon may have come. This is not supported by evidence of higher rotational speed in the past.
  • CAPTURE : If the Moon formed separately, it could have come close enough to the Earth's gravitational field to be trapped. The angle of orbital approach would have to be within narrow parameters in relationship to the moving centre of the orbiting Earth. The chance of this occurrence is very low without some other gravitational interaction
