What else can I help you with?
What is a small spherical object that orbiting the sun?
A small spherical object orbiting the sun would be called a planet, asteroid, or comet, depending on its characteristics and orbit.
What was Aristotles basis for believing that the earth was spherical?
First he realised that eclipses of the moon were caused by the earth coming between the sun & the moon. The earth's shadow on the moon was always round, which would be true only if the earth was spherical.
What would be its relative strength at the new surface if Earth shrank to half its size?
Assuming that by "it" you mean the gravitational force, the amount gravitational force of an object with spherical symmetry (Earth basically has that) on an outside object is the same as if the entire mass (of Earth, in this case) were concentrated in the center.Thus, and assuming you mean you shrank Earth WITHOUT changing its mass, you would get half the distance, and therefore four times the force.
Is Earth a spherical planet?
Yes earth is a spherical (round), thousands of years ago people did not know that planet earth was round, they just thought it was flat so if they went to far they would fall of the edge! but nowadays because of spacetravel etc, we have seen planet earth and they have noticed it was a spherical planet. So yes it is.
Why are all the layers of the earth spherical?
Because the earth is held together by gravity and also because if they were not new plates would not form.
What would happen to earth if it is flat?
No change in day or night, or any change in seasons, these occur because of Earth spherical property
What is the shape of an object that would be the best model for the earth?
A sphere is the best model for the Earth, as it closely represents the planet's actual shape. While Earth is not a perfectly round sphere due to its rotation, it is an oblate spheroid, meaning it is slightly flattened at the poles and bulging at the equator.
What would have to happen in order for Earth to become a perfect shape?
For Earth to become a perfect shape, it would need to be perfectly spherical. This would require it to have a uniform distribution of mass and no geographical features like mountains or valleys. Achieving a perfectly spherical shape would mean Earth would have to be completely smooth and free of any irregularities.
How do you know that the earth is spherical and not flat?
Because people have seen it from space and anyway if the Earth was flat all the water would fall of the edge so then we would not survive
What is the nearest natural object to the Earth?
The Moon is the nearest natural object to Earth in space.
If the earth is round why does it seem?
Even though the earth is round, or more specifically, spherical, it seems flat to the human eye. This is because the earth is so huge that when we look at it we can't take in all of the horizon because we are so close. If we were viewing the earth from the moon, we would clearly be able to see it is spherical.
Would an object have the same mass density on the moon as it does on earth?
No, the mass density of an object would not be the same on the moon as on Earth. The mass of the object would remain the same, but since the gravitational pull on the moon is weaker than that on Earth, the volume of the object would decrease on the moon, resulting in a different mass density calculation compared to Earth.
