When the Earth was formed it was molten. The forces of gravity would make it shape itself into a sphere. This shape would be "frozen" in place as the Earth cooled and solidified.
Sun's Gravitational force.
Gravity..
The ancient Greeks had worked out that the world was round by looking at the shadow that the Earth makes on the moon. Colombus knew it was round.
The earth's gravity field makes everything push into the earth like a bubble arround the planet. This makes it seem like the earth is flat.
Earth is round because of the gravity around it makes it all shaped in the old or ''new''earth is now what we call a sphere or a ball not a circle because that is only 2D not 3D.
It is called a great circle and the plane that circle makes must pass through the geometric center of the globe. The largest circle that can be drawn round the Earth is the great circle round its middle, the "equator" this is because the spinning of the earth makes it 'fatter' round the middle.
umm: "The Earth is round"? ------------------------------------------------ The Earth is not round - it is an oblate spheroid. ---------------------------------------------------------------------------- A (slightly) oblate spheroid seems pretty "round" to me.
Pythagoras stated the earth was round
Yes, it is a fact that the Earth is round.
The moon rotates round the Earth.
all year round unless its a leap year. something about the way the earth aligns with several other stars. it makes the earth not fertile for a short time.
An orbit is usually when one heavenly body makes a complete circle round another. For example: Earth orbits round the Sun.
