Why are rocks on the moon older than any rocks on earth?
On Earth, plate tectonics and erosion have removed all of the rock that was originally surface rock, exposing the underlying crustal rocks and releasing magma to form new igneous formations. On the Moon, neither process is at work. Meteoroids striking the Moon have piled the rocks up and created a layer of fine powder there, but the exterior rocks are still those that formed shortly after the Moon itself.
Is the Earth older than the Sun?
No, the Sun is older than the Earth.
Is the fault older or younger than rock layer A?
The fault is younger than rock layer A. This is because faults are fractures in the Earth's crust that form after the deposition of rock layers, and activities like faulting can occur long after the rock layers have been deposited and solidified.
Where would you weigh the most on earth or the moon?
You would weigh more on Earth than on the Moon. This is because weight is a measure of the force of gravity acting on an object, and the gravitational pull on Earth is stronger than on the Moon.
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.
Why is the moon older then Earth?
The earth is not younger than the moon
Rock samples brought back from the moon during the polar space program where older than rocks found on earth?
true
What planet is rock and ice and smaller than Earth's moon?
Pluto, which is no longer considered a planet, is made of rock and ice and is smaller than Earth's moon.
Is the moon older then the sun or earth?
None. Both the sun AND earth are older than the moon. No. It appears that the Moon is slightly younger than the Earth. Current theory for its creation is that an object, a protoplanet about the size of Mars called Theia, struck the Earth during its early formation, ejecting matter that consolidated into the Moon. The Sun is older than both the Earth and Moon, but only by a small amount.
Is the weight of a rock different in the moon than the earth?
YES!
Why are the rocks on the moon found to be older than the rocks on the earth?
The moon does not have an active geological process which constantly recycles, and recreates itself. The earth does.
How much do a rock weight from the moon?
The overwhelming majority of moon rock is basalt, a very common volcanic rock. Earth has more basalt than it knows what to do with. Two equal volumes of basalt, one from earth and the other from the moon would weigh just about the same (on earth).
Why are there rocks on the moon that are older than any rock 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 old is the meteorite in Allende Mexico?
It is estimated to be 4,567 billion years old; older than Earth and much older than the oldest rock found on Earth.
Does a rock weigh more than a moon?
No. Any object on the moon would weigh about a sixth of what it does on Earth.
Which is older rocks found on the moon or rocks found on the earth?
Rocks found on the moon are older because of the lack of erosive forces there. Also, the moon would have cooled more quickly from a molten state than the much larger Earth.
Will a rock sink in water on the moon?
Yes. The weaker gravity on the moon does not change the fact that rock is denser than water. The rock will sink more slowly than it would on Earth, but it will still sink.
