Is it true that a meteorite collided with earth and then create the moon?

Answer 1

No it is not. The moon was created.

Secular scientists have devised four major theories for the moon's beginning.

1. The fission theory states that the moon split off from the spinning earth, like mud flung from a bicycle wheel. Some say that the Pacific Ocean basin is the scar that remains from this loss of material. There are four basic problems with this theory. First, today's earth and moon do not have nearly enough circular motion for fission to have ever occurred. Second, although a moon split off from the earth would be expected to orbit directly above the equator, in actuality the moon's orbit is always tilted between 18 to 28 degrees to the earth's equator. (This is the reason why the moon appears higher or lower in the sky during different seasons.) Third, while the moon was moving outward from the earth, gravity would have pulverized it into Saturn type rings. Fourth, moon rocks are somewhat different from the equivalent material on earth.
2. According to the capture theory, gravity brought the moon into earth orbit when it once wandered too close to earth. The main problem with this theory is the low probability that two space objects would pass each other so closely. Another problem involves the actual "capture" mechanism: it simply wouldn't happen! Instead, the moon would continue on its journey. We have often sent space probe "fly-bys" to other planets and they are not captured, but instead are thrown outward with great speed, as in a crack-the-whip game. Finally, capture doesn't really qualify as an origin theory since it assumes the moon's prior existence.
3. The third theory has several names: condensation, nebular contraction, or accretion. It proposes the concurrent formation of both the earth and moon from small chunks of material. As a result, the moon "just happens" to circle the earth. The main assumption here is that the material would actually fall together into a big lump. Force calculations rule out such a collapse unless the cloud of material is already quite dense. Present-day dust clouds observed in space are nowhere near this dense.
4. The fourth lunar-origin theory calls for a collision between the early earth and another planetary object, an impact causing an orbiting cloud of debris that eventually grouped itself into the moon. Some critics of this theory believe that such a giant impact would totally melt the earth's crust. Others question the probability of another object's hitting the earth with the precise speed and direction needed to result in the formation of a moon. The main reason for promoting this idea is that none of the other lunar-origin theories works!

Answer 2

Thats one theory that works in computer simulations but since nobody was around to witness it and write it down we will never know for sure. Based on the work done and the possibility of other theories I would tend to believe this one and the most probable.

In the theory a large meteorite, so large it's often referred to as a proto-planet, collided with the earth and ejected large amount of mass into near earth orbit. This collision also imparted a great deal of rotational momentum to the earth and is at least partly responsible for the earths rotation. Any way back to the moon, the ejected debris formed into a large mass that is the moon we see today.

That's pretty much the cliff notes version.

Answer 3

Actually there are some theories ,posted by the previous users. Every astronomer believes in a different theory ,but it seems that the Mars-sized planet collision is most alike to be the cause of the creation of the Moon.On the other hand that doesn't explain its mineral structure ,which is so different from Earth's ,so this theory has a weakness (like every other theory).Another theory is that the Moon has been "captured" by Earth's gravity field. This theory also has flaws.It is more possible that the Moon had been attracted by Earth and hit us.On the other hand , that is pointing to the previous theory ,so maybe the truth is in the middle.

Answer 4

Actually, a planet the size of mars crashed into the earth, tore of much of the earths mantle, and threw it into space in orbit around the earth, which eventually coalesced into the moon. There is much evidence to support this theory, and so far no other model has been brought to the table that can explain all the evidence. It's pretty much a closed case.

Answer 5

the moon isn t and never been an earth chunck hurled into space by some massive collision between the earth and another body.it is a rock which has been there since the earth formed.it was created at the same time and it has never supported any atmosphere or life.there is water under its ground and its core can be hollow in some places.it does experience some mild quakes but never as violent as what we have on earth.it s got a flag on it and its colors have lost a bit of their original brightness.

Answer 6

Not a meteor, but a Mars-sized mass.
