How our planet got an ovel shape?

Answer 1

Our planet wasnt always solid, in the beggining it was made of hot viscous material.

Our planets gravity well pulled materal (Interstellar dust, comets, asteroids etc...) out of our forming solar system and impacts from this material caused it to start rotating.

The rotation (along the equator) caused a centrifugal force which pulled matter outwards making our planet elliptoid.

In fact, if the rotation was faster our planet would be a flat disk and Aristotle would be wrong : )


Fun Fact: This is why you weigh more on the equator than on the poles!

Answer 2

To a first-order approximation the Earth is round. This
is due to gravity. Gravity pulls with equal strength in all
directions; therefore any variations from a spherical
shape will lead to gravitational forces that
bring the shape back into that of a sphere.

This is without considering the rotation of the earth,
however. The rotation of the earth adds centrifugal
effects, which cause the earth to bulge slightly at
its equator and flatten slightly at its poles.
(This is like twirling a rock on the end of a string
and then letting go--the rock flies away from the
twirler.) Because of these centrifugal effects, the
distance from the center of the earth to the surface
of the earth is about 0.33% shorter at the poles
compared to the equator

Answer 3

Spere is the shape that you can have the largest volume from having surface being at the least distant from the centre.
As an example if we compare a cube and a spere having the same volume, the distance from the centre to the surface is less in the spere.

Due to the huge gravitational force matter in the earth is always attracted towards the centre. So sphere is the formation where all the mass can be kept at the least distance from the centre.

Answer 4

The earth is not exactly an oval but a sphere that is flattened at the poles. This is attributed to many theories currently in question.
One theory states that the earth due to continuous revolution and due to the act of the centripetal force has flattened due to the speedy rotation on its axis.
Another states that the gravity of the moon which moves in an angle to the equator is responsible for bulging at the equator and thus flattening of the poles.

Answer 5

Earth initially was a mixture of hot gaseous materials separated from the parent sun. By time passes, it became cool & thus slowly liquid & solid appears in the earth. But the gravitational force attracts all these contents towards its centre. As sun was being rotating in an axis through its centre, all gaseous materials when converted accumulated in around equidistants from the centre. Thus earth got oval shape.

Answer 6

The shape of Earth is not oval,it is an Eclipse or Oblate Spheroid.
This shape is due to the Coriolis Force constantly acting on it
& also due to the Gravitional Pull

Answer 7

My answer is that you need to take a GRAMMAR class and the answer to the question is that the planet is oval so that the layers inside the earth can be equal. Incase you don't know what layers are here you go: the layers in side the earth is what makes it round, and it makes the planet (earth) together. Inside the earth is 900,000 degree weather with hot magma which is what comes OUT of volcanoes.

Answer 8

Our Earth has got nearly spherical shape. As we know, the most stable shape in this Universe is spherical shape. So after separation of planets from Sun, they formed into spherical shape. But due to the internal layers formation, it slightly bulges at equator. But really, it is not in oval shape.

Answer 10

The high rotational speed of the Earth causes the center of it (equator) to bulge outwards. this is more noticeable at the equator because of centrifugal forces.
