How old were the lunar rocks Apollo brought back?

As old as the moon, or younger. Probably most were remnants of asteroids or pieces of moon that were blown off when an asteroid collided with it. Scientifically? 4.6 billion years old.


How have the moon rocks that astronauts brought back to earth help scientist understand the history of the moon?

The moon rocks that astronauts brought back to Earth foe scientists to understand the history of the moon by having them study how old the moon is and determine its age. It can also tell the layers which now we already know. Also the moon pieces helped us determine how the surface of the moon is like with out going there, which saves money. - Angie Plata


How old were the moon rocks bought back by astronauts?

13 years old


How old were the lunar rocks brought back by the Apollo missions?

About 4.6 billion years old.


How can new information affect an old explanation for something?

It was not known how the Moon formed until the Apollo astronauts brought back Moon rocks. It was then found that the rocks were similar to the Earth's showing that a planet had hit the Earth and scooped out a chunk of the mantle. Prior to this it was thought that either the Moon was a captured asteroid or had formed at the same time as the Earth from a disc of dust.


How old was the lunar metal brought back by Apollo 11?

The Lunar craft crashed on the moon, they did not bring it back to earth.


Radioisotope dating of moon rocks showed that the age of the oldest lunar rock was closest to how many years old?

Rocks from the moon have been dated to about 4.5 billion years old. The oldest earth rocks don't date that far back because the earth "reprocesses" rock, and the oldest rocks we know of on earth date back to about 3.7 to 3.8 billion years. The earth and moon formed at approximately the same time, as did the rest of the solar system.


How old are rocks found in Apollo missions?

The moon rocks are older then the rocks found on earth.


Why are there rocks on the moon that are older that any rocks on earth?

There is no geologic activity or weathering on the moon to break rocks down, so most of the rocks on the moon are nearly as old as the moon itself. Earth is geologically active and has processes that will destroy and recycle rocks. None of the rocks that made up Earth's original surface are still intact.


How are moon rocks used to determine the age of the Earth?

The oldest moon rocks are actually older than the oldest Earth rocks. The moon formed from accreted material that resulted from a collision between Earth and a Mars sized protoplanet. Both the Earth and the moon were molten for a period after the collision. Because of the moon's smaller size, it's surface cooled very quickly compared to the Earth. The solidified magma (rock) that formed the moon's crust has been dated at roughly 4.4 billion years of age. Even though no Earth rock has been found to date this old, we can still reasonably assume that the Earth is at least that old due to the fact that the moon is formed from accreted material from the previously mentioned collision.

What evidence is given to tell how old the moon is?

Using standard radiometric dating of rocks returned from the Moon by the Apollo missions.
