How do the effects of gravity show that earth is almost spherical?

Proof of earth's shape is that earth casts a curved shadow on the moon during a lunar eclipse. Something flat like a book casts a straight shadow whereas objects with curved surfaces casts curved shadows.

∙ 12y agothis is because since gravity constantly pulls earth's poles, they begin to compress. Then the equator bulges out slightly because since the gravity compresses the poles earth cannot be a perfect sphere.

What is the center of gravity for a spherical object?
If the object is homogeneous, its center of mass is in its geometrical center. And if it is small compared to Earth, its center of gravity is, for all practical purposes, its center of mass.
How gravity does effects objects?
Gravity pulls objects towards Earth. Or, in more general terms, towards any mass.
What is the accelaration gravity of the center of Earth Surface?
At the earth's center, the acceleration/force of gravity is theoretically zero.(At least the force of gravity between the earth and an object at its center. There's still the gravitational forcesbetween the object and everything else ... the sun, moon, stars, etc.)
Is there gravity in the exosphere how much?
Since that is very near to Earth - compared to Earth's radius - the gravity will be almost the same as on the surface. If you want to know exactly how much the gravity gets reduced, look up the distance, and use the formula for gravitation.
What is curvature of earth?
The Earth is a sphere. It is shaped like a sphere because gravity shapes it this way. For this same reason the moon, sun, and other massive bodies in space are also spherical.
Is your earth spherical if yes then how?
Gravity
What fore gave earth its spherical shape?
Gravity.
Is the earth really spherical?
The Earth is almost spherical. It's slightly squashed, or oblate.
Why do you say earth is spherical?
The earth is spherical because the gravity pulls all the sides towards the core and its equal gravitational pull all round so this ceates a speherical like shape.
Why is earth spherical in shape?
That is due to gravity. Any large deviation from a spherical shape - such as a mountain that is more than a few kilometers high - would be squashed down by gravity.
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.
Does the earth or Venus have more gravity?
Earth (by definition has a gravity exerting a pull of 1g. Venus is almost the same as Earth but the pull of gravity there is 0.904g. So Earth has more gravity.
What planets have a surface gravity almost the same as earth?
earth
Why doesn't the gravity of the sun and moon affect us?
It does. Earth is moved by the gravity of the sun and, to a lesser degree the moon. We are move by almost the same amount and so we move with Earth. Since Earth's surface is our point of reference and we are moving with it, we don't notice it. We observe the effects of the gravity of the sun and moon in the tides.
Is there gravity on Mars less earth?
Yes. The effects of gravety on Mars are less than on Earth. Mars has 37.6% of Earth's gravity.
What is Venus's gravity?
almost the same to earth
Why does Eros have an irregular shape instead of a spherical shape?
Jupiter's gravity It is not massive enough to pull itself into a spherical shape like something the size of the moon or Earth.
