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.
The rectangular shape avoids the curvature of light where as the spherical shape will bend it and give an inaccurate reading of absorption.
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.
The most spherical object in the universe is believed to be the star Kepler 11145123, which is nearly perfect in its spherical shape.
An orange is an everyday object that has a shape similar to Earth, with a round and spherical shape.
Because it's spherical object
spherical.
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.

The Earth is approximately spherical in shape, specifically an oblate spheroid. This means it is mostly spherical but slightly flattened at the poles and bulging at the equator due to its rotation.

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.
The Moon is spherical in shape mainly because of gravity. When the Moon formed, gravity pulled its material toward the center from all directions. Over time, this force helped shape the Moon into a nearly round object. A sphere is the natural shape that a large celestial body tends to form when gravity is strong enough to overcome the unevenness of its material. This process is called gravitational equilibrium. The Moon is not a perfect sphere, though. Its rotation and internal structure make it slightly irregular. In simple terms: The Moon is nearly spherical because gravity pulls its material toward the center from every direction, creating a rounded shape.
Two criteria for a space object to be considered a planet are: (1) it must orbit the Sun, and (2) it must have enough mass for its gravity to pull it into a roughly spherical shape. Additionally, it must have cleared its orbit of other debris.
