Relative to the oldest rocks that have been found on the moon, the oldest rocks found on the earth are?

Question

a. younger
b. about the same age
c. somewhat older
d. very much older

Answer 1

A. Younger. (I win. I was the first with the correct answer.)

Added Info: To correct the guy below me...the Earth is 4.6 Billion years old and the moon 4.5 BYO. It is a FACT that it was formed by a collision with a mars sized object smashing into Earth when Earth was still in a molten state. The question asked about the "oldest rocks" found on both. Although the moon has been struck by countless meteoroids, comets and even asteroids since that time, the "oldest rocks" found on the surface are part of the original surface (4.5 BYO) and are therefore older that Earths surface rocks. The Earth has undergone many resurfacing changes since then, including constant shifting of the continental plates, the massive comet bombardment period which gave us all the water, and the 100 tons of space dust which makes it to the surface each day. The oldest rocks ever found on earth were about 3.7 Billion years old in Greenland. Next oldest are some found in part of the Grand Canyon and have been dated to about 3.2 Billion years old. Therefore...answer A is correct. (Younger)

Answer 2

The Moon was formed about the same time as the Earth, and there are some who believe the Moon was once part of the Earth before a collision with another small planet or very large asteroid striking the earth. They are about the same ages. Some portion of the Moon rocks may have a composition different than the Earth due to the large number, and massive size, of asteroids hitting the Moon.

Answer 3

b.
