Question

Explain the reason behind the Earth's round shape

Answer 1

Because gravity acts pretty much in a straight line. As the swirling dust clouds collected into the earth, the particles acted on each other to form clumps, and the clumbs attracted to each other, then you end up with a nucleus of matter imparting a gravity field radially out from the centre. Things will be colliding with the nucleus from all directions with an equal probability and thus a sphere.

Answer 2

If i was square, it might poke out Pluto's eyes.

Answer 3

gravity. Part of the definition of a planet, as opposed to an asteroid, is that it must have enough gravity to be round.

Answer 4

because when the earth was formed it was all molten mass. and all liquids take the form of a sphere , like rain drops. Because for a given volume the sphere has the least surface area and is most stable. So the earth is round

Answer 5

i believe that God created the world in a shape that he could manage best.

Answer 6

gravity and centripital force has something to do with it

Answer 7

THe earth needs to rotate around the sun and therefore it was forced to be round

Answer 8

god made the world round so that the gravity of the earth would be right to keep the other planets a certain distance from it. if the earth were square there would be an angle that did not that the same amount of gravitational pull and it would throw all the planets out of balance. so the earth is round so that there is even gravitational pull from all angles

Answer 9

Because of gravity

Answer 10

Planets are round because their gravitational field acts as though it. originates from the center of the body and pulls everything toward it.. With its large body and internal heating from radioactive elements, a. planet behaves like a fluid, and over long periods of time succumbs to. the gravitational pull from its center of gravity.. . 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.. . 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. . . . . . http://www.pa.msu.edu/~sciencet/ask_st/031198.html. . http://ideaplace.org/Why/RoundPlanet.html
