Why is the world round?

Question

And all the other planets in the solar system....what makes them spherical?

Answer 1

Forces are balanced in a sphere in all directions-It is the only shape that can do this.

Answer 2

Planets are not round, they seem to be spheres, not cubes or cylinders or oddball rocky shapes. Some smaller bodies such as asteroids or Mars moons Phobos and Deimos, do have odd shapes, but larger bodies like the nine planets and most of their moons do look like spheres. That's because of the nature of gravity. You can think of gravity as a force that points inward toward the center of the planet so that every part of the surface is pulled evenly toward the center, resulting in a spherical shape.
Of course, planets are not perfect spheres because mountains and valleys and even skyscrapers are all deviations from the spherical shape. However, as planets get larger, gravity gets stronger, until eventually large objects on the surface are crushed under their own weight. That's why we don't have mountains that are 50 miles high or skyscrapers that are 2,000 stories tall. Planets stay basically spherical because any large deviations get crushed.

Although gravity keeps planets close to spherical, there are other forces that cause deviations from the basic spherical shape. For example, the rotation of the earth once every 24 hours, causes an apparent centrifugal force which creates a bulge at the equator. In fact the earth's diameter at the equator is 7,926 miles while the diameter between the poles is only 7,900.

Answer 3

Every material in liquified form tends to get lowest volume, like a drop of water.

Now since the earth in the begining was not solid it took to round shape to reach the lowest volume.

And so are all stars and planets...

Answer 4

What makes them Spherical?
I should say, "Who makes them spherical"
God did.
Why? So the gravity would be even.
One more thing, It's not exactly a sphere.
It is somewhat flattened at the poles.

Hope this helps.

Answer 5

Something to do with gravity

but not all planets are spherical due to bombardment of space matter

Sorry can not be of anymore help

Answer 6

Gravity pulls a planet into this shape. They need to be about 200 miles in diameter for this to start

Answer 7

the world round because of all attoms of soft liquids bond together. these bond find it way to pack it up....our world is most of water (sea). and center in hot liquid too.......just like a drop of water become round in space.....but why moon round too. maybe long time ago a big bang everything is melt and hot, just like chocolate melt turn in to liquid in space and it form round. when chocolate cool down.....it hard example of moon.

Answer 8

Because they are spinning. They were melted. The centers are hot and they are slowly cooling off.

Answer 9

it is not round. it is a globe with a bulge in the middle at the equator.it is slithly flat

Answer 10

The circle is like infinity.
