large chunk of the earths crust gone.?

Question

Do you think that,The reason 4 this is.At one time the earth was in a liquid state,and it's mantel was molten.then at that time a very large chunk of water was pullded out of the ocean and pullded into space witch is how the moon was formed formded,this is why a large chunk of the earth's crust is gone.

Answer 1

No, I do not think the moon is part of our earths crust. I do believe it has folded over, causing a large surface area of crust to appear as missing, because of plate shifting. The crust may be staked or possibly flipped on top of another section. It will be interesting to find out the truth.

Answer 2

At the time Earth formed 4.5 billion years ago, other smaller planetary bodies were also growing. One of these hit earth late in Earth's growth process, blowing out rocky debris. A fraction of that debris went into orbit around the Earth and aggregated into the moon.
The Earth has a large iron core, but the moon does not. This is because Earth's iron had already drained into the core by the time the giant impact happened. Therefore, the debris blown out of both Earth and the impactor came from their iron-depleted, rocky mantles. The iron core of the impactor melted on impact and merged with the iron core of Earth, according to computer models.

Earth has a mean density of 5.5 grams/cubic centimeter, but the moon has a density of only 3.3 g/cc. The reason is the same, that the moon lacks iron.

The moon has exactly the same oxygen isotope composition as the Earth, whereas Mars rocks and meteorites from other parts of the solar system have different oxygen isotope compositions. This shows that the moon formed form material formed in Earth's neighborhood.

If a theory about lunar origin calls for an evolutionary process, it has a hard time explaining why other planets do not have similar moons. (Only Pluto has a moon that is an appreciable fraction of its own size.) Our giant impact hypothesis had the advantage of invoking a stochastic catastrophic event that might happen only to one or two planets out of nine.

Answer 3

If any part of the Earth's crust were missing then we would be looking at the mantle. A quick scan of the Earth reveals no mantle on the surface of the Earth, either on land or under the oceans. Therefore, no part of the Earth's crust is missing. The creation of the moon was so long ago, and when the Earth was molten, so there was no crust at that time on the Earth. I disagree with Chris M's answer. I have seen lunar rocks and they are similar to mantle rocks found in maar volcanoes from kimberlite pipes in southern New Mexico.

Answer 4

Answergirl answered it well. The only thing I would add is that the favored theory now is called the cold accretion theory. It suggests that there was never a melt in the outer mantle or crust except under special circumstances such as volcanoes. I don't know anywhere where the earth's crust is gone. If something impacted the earth to form the moon, it is unclear where that happened.

Answer 5

The crust is not missing it either didn't form or was pushed aside by tectonic actions.

By the way the moon is not made of water.

Answer 6

Thre technical term is called Pizza Crust. I think it's origins are Dutch.

Answer 7

Did this come to you in a dream? The make up of the moon in no way resembles materials found on earth.

Answer 8

Whoa.
All I can say is to go take some basic geology and earth science courses.

Answer 9

No.

It was once sorta liquid but that was along time ago.
