nothing much
The circumference is the distance around the Earth at it's widest point. The diameter goes through the center of the Earth from one side to the other.
The theory that the Sun revolved around the Earth (i.e. that the Earth is the center) is called Geocentricity. The theory that the Earth revolves around the Sun (i.e. that the Sun is the center) is called Heliocentricity.
It means that is where all the gravity goes
The Latitude is the line
The horizontal line that goes around the "waist" of the Earth is the Equator. The vertical line that goes vertically around the Earth, through the poles, is the Prime Meridian.

No, if someone went into the center of the earth, they will find a relaxing place to let all their trobles drift away... DUUUUUUUHHHHHhhhhhh of corse you would die!
Aristotle did not believe that the sun goes around the earth. He proposed a geocentric model of the universe where the earth was at the center and celestial bodies moved in circular paths around it.
Heliocentric means the sun is the center - everything goes around it. Geocentric means the Earth is the center and everything goes around us.
Gravity seems to be an inherent property of mass; the more mass, the greater the gravity. It has nothing to do with the spinning of the Earth.
That all depends on the shape of the object and how its mass is distributed. The center of gravity of a solid sphere is at the center of the solid sphere. The center of gravity of a solid cube is at the center of the solid cube. The Earth's center of gravity is at the center of the Earth, and there's certainly plenty of mass there. But the center of gravity of a ring is at the center of the ring ... an open space where the finger goes.
when the moon goes straight through the center of the Earth's shadow, or at least close enough to the center that there is some time when the moon is completely in it
