Is the moon and earth solid?
The Earth is solid except for the water, the Moon is solid, but scientists have found frozen rivers...
Why is moon rock older than earth rock?
The rocks on Earth are continuously melted or broken down and recycled by geologic activity, so none of the original surface rock of Earth remains intact. The moon is geologically dead, so rocks are not broken down or melted.
What is wrong with calling a rock that strikes the moon a meteorite?
Because a "meteorite" is a rock that passed through the Earth's atmosphere, was heated to incandescence by pressure and friction, and then struck the Earth. A space rock that hits the Moon didn't land on the Earth. However, this is a pretty minor distinction, and some space scientists use the term "meteorite" for any rock that falls from space, whether to the Earth, the Moon or Mars. NASA has occasionally used the term "meteorite" for rocks found by the Mars rovers Spirit and Opportunity.
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.
Is the moon and the crustal rocks of earth are similar in density?
Yes, the Moon's density is about 60-70% that of Earth's crustal rocks. This is due to differences in composition and size. The Moon's crust is mainly made of less dense rock types compared to Earth's crust.
How many kilos of rock were brought back from the Moon?
In total, 381.7 kg of rock was brought back to the Earth from the moon during the Apollo missions, which were the only missions ever to land men on the moon.
What Apollo mission brought back the moon rock?
The following Apollo mission each brought moon rocks back to earth, they were Apollo 11, 12, 14, 15, 16, and 17.
If you put a moon rock on the earth would the weight of the rock change?
No, the weight of the moon rock would not change if it was brought to Earth. Weight is a measure of the force of gravity acting on an object, which would be the same on the moon as it is on Earth. The mass of the rock would stay the same as well.
How much moon rock was brought back to earth by the Apollo space missions?
about 860 kilos
What was the moon rock called?
The moon rock brought back by Apollo 11 was called "Sample 10057".
What has more mass a rock in earth or a rock on the moon?
a rock in earth
How much moon rock did Neil Armstrong collect?
Neil Armstrong collected about 47.5 pounds (21.5 kilograms) of moon rock during the Apollo 11 mission. This rock and soil were brought back to Earth for scientific study.
How much moon was brought back to earth?
PARTIAL ANSWER:Over 800 pounds of moon rock have been returned to earth but I'm not sure of soil samples which would add considerably to that number.
Rock samples brought back from the moon during the polar space program where older than rocks found on earth?
true
Is moon rock inorganic?
Yes. Moon rock is similar to volcanic rock on Earth.
Why are the oldest rocks found on earth younger than the oldest lunar rock that Apollo brought back?
The Earth has lots of tectonic activity, by which I mean earthquakes and volcanoes, which the moon does not have. Rocks can survive longer on the moon.
A rock is taken from the surface of the moon and brought to earth what is different about this rock on earth?
The main difference is that the rock's appearance may change due to exposure to Earth's atmosphere, causing potential oxidation or weathering. Additionally, the rock's composition could be altered as it interacts with Earth's environment, leading to potential chemical reactions that could affect its structure. Lastly, the rock's weight will be different on Earth due to the moon's lower gravitational pull compared to Earth.
