best answer:
once upon a time they were both a single planet,
a major collision flung off enough material to form the moon
(and to spin the remaining Earth so that we now have a 24 hour day)
The Earth is an inner planet, and all the inner planets are rocky. The Moon is made out of the same matter as the Earth, so yes, they are both rocky spheres.
The weight of the rock would be less on the moon compared to Earth due to the moon's weaker gravity, but the mass of the rock would remain the same.
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.
No. Since the moon is not geologically active it cannot produce metamorphic rock and since it has no forces of erosion and deposition it cannot produce sedimentary rock. As a result, all the rocks on the moon are igneous
The mass of a rock remains the same regardless of whether it is on the Moon or Earth; mass is an intrinsic property of matter. However, its weight will differ due to the varying gravitational forces exerted by each celestial body. The Moon's gravitational pull is about one-sixth that of Earth's, so a rock will weigh significantly less on the Moon than it does on Earth.
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).
The earth becomes a litle lighter and the moon becomes a little heavier.
180 grams of mass ... liquid, solid, gas, whatever ... weighs about 6.35 ounces on Earth and about 1.05 ounces on the surface of the moon. Any mass on the moon weighs 16.55% of its Earth weight.
Pluto
They are al in space, and made of the same materials and atoms.
A rock's mass is not affected by the moon. It's weight is a function of mass and gravity. So, the same rock would weigh more on Earth than on the Moon, as the Earth's gravity is greater. In order to effectively confuse the issue, I should point out that gravity is also a function of mass...
If two identical rocks, labeled "N rock" and "N rock," fall from the Moon, they will fall at the same rate regardless of their labels. This is due to the uniform gravitational acceleration on the Moon, which is about 1/6th that of Earth. Therefore, both rocks will hit the surface simultaneously if released from the same height and under the same conditions.
