Mercury has about the most perfectly spherical shape, but Saturn has the least
spherical shape (next least spherical is Jupiter).
Small objects such as asteroids and comets are the least likely. Gravity cannot shape such small objects into spheres, so many asteroids and comets assume elongated shapes.

The rectangular shape avoids the curvature of light where as the spherical shape will bend it and give an inaccurate reading of absorption.
Spherical shape has minimum gravitational potential energy and everything in nature aspires for least potential energy i,e maximum stability.So all heavenly bodies are spherical in shape.
because there has to be some kind of distortion of earths spherical shape
When the force is a balanced force there is no movement. So when the balanced force is acted upon an object that is malleable, the object will change shape to accommodate the force since it cannot move. just to restate it a different way Basically it must be a balanced force to change an object's shape. In the case that the object is malleable the object will change shape until more force is necessary to change it's shape. example if two boys use the same neuton of force
Yes it is. Surface tension caused by hydrogen bonding within the water is the reason. Hydrogen bonding is caused by the strong polar nature of the water molecule. It's polarity means the positive end of one molecule is attracted to the negative end of another molecule.
Because it's spherical object
spherical.
Its the same reason as to why every other heavenly body is spherical in shape. its because any rotating body in order to conserve energy takes the shape involving least tension and hence your planets, moons are spherical in shape.

It depends on the shape of the object. A spherical object will fall faster than a rectangular object. This is untrue if they are placed in a vacuum.
The object becoming more spherical. The object increasing in size, but maintaining a similar shape.

A dwarf planet.
[object Object]
The IAU has declared that a stellar object must be spherical or circular in shape and must orbit the Sun. Oh the shape of the object must be a result of its own gravitational mass.
The round (spherical) shape of a planet comes about through the force of gravity, not through wind, but the rotation does have an effect on its shape. Mass is related to gravity, the more massive an object is the bigger the force of gravity at its surface. If an object is around 700-1000km in diameter (roughly) then it will have enough gravity for it to shape itself into a ball shape, overcoming the internal forces that would otherwise give it an irregular shape. A object (like a moon, dwarf planet or planet) has to be large enough and massive enough to 'pull' itself into a spherical shape. The spin of the object may cause the spherical shape to become squashed, if it is fast enough, as the centripetal forces at the equator will stretch it out somewhat.
They are not spherical
