Is Earth is round or spherical?

Answer 1

According to certain earth science satellites dating to the late fifties the planet has a slightly pear-shaped orb. It might be observed that there have been myths and religious beliefs such as those of the Brahmans which hypothesized a sort of doughnut or egg-shaped cosmic soul-Looking somethiing like the oval cloud advertising logos of some airlines like Twa, and this ws flattened slightly to give more of an oval, not relaly spherical shape. Maybe the myths were not so far off!

Answer 2

Earth is technically an oblate spheroid, which means it is mostly spherical but slightly flattened at the poles and bulging at the equator due to its rotation. This shape is a result of the planet's gravity and rotation.

Answer 3

The Earth is not perfectly round for at least three reasons. The first reason is that the Earth is somewhat flexible so it bulges outwards at the equator because of its rotation. The second reason is that the land masses are not distributed evenly and their weight presses down on the Earth, "dimpling" it slightly. The third reason is because geologic processes keep thrusting up mountains and erosion keeps digging out valleys so the Earth cannot be perfectly smooth.

Answer 4

No, although the planets may seem spherical, they are actually flattened somewhat at the poles. The planetary spin on its axis pushes the equatorial part outward. Saturn, for example, has a radius of 54,300 km toward the poles but 60,200 km toward the equator. Earth is much closer to spherical with only a 22 km difference between the polar radius vs. the equatorial radius.

Answer 5

Approximately, yes 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.
Because all the material is pulled towards the centre of gravity and if it was not round there would be slopes for material to roll down. After 4 billion years all the rolling that could be done has been done.

Answer 6

The original shape of the earth is oblate spheroid,one example is the ball

Answer 7

Only on Sundays because the ground is mushy. Unless the swirly thing in America falls down. If we walk the Earthwill explode!!

Answer 8

No, the earth bulges at the equator. It is an oblate spheroid.

Answer 9

As it applies to shape, the word "round" applies to two dimensional figures only; a circle. A three dimensional object, such as the earth, is a sphere (or nearly so).

Answer 10

Almost but not quite. The polar regions are somewhat flattened so the earth is not a perfect sphere.
