Yes. Rock forms around a larger rock. The mass of the planet increases enough to gain more gravity and crushes the rock around it compacting and smoothing it into a sphere. Also, nothing could exist without gravity.
It isn't. Gravity is a force created by mass in spacetime; the centre of the Earth is a particle of matter.
The gravity of Earth is 2.6 times that of Mars.Mars's gravity is 38% of Earth's gravity.
Because the gravity of earth was closer together.
Pluto's force of gravity is equal to 0.58m/s2, whereas the force of gravity on Earth is 9.81m/s2. Thus, the gravity on Pluto is about 6% that of the gravity on Earth.
It has 252.8% of earth's gravity.

There has to be gravity or will we float away. This is why mass and volume were created. To keep on us on the ground. You can't feel gravity but it will always be there. There is a force of attraction between all masses in the universe; the gravity we feel is the attraction between Earth's mass and the mass of our bodies on Earth's surface.

No. The earth has its own gravity. The lunar gravity causes tides on earth, but does not control earth's gravity.
No - the gravity of Earth is due to its mass.No - the gravity of Earth is due to its mass.No - the gravity of Earth is due to its mass.No - the gravity of Earth is due to its mass.
Because the gravity of earth was closer together.
Because water is pulled down by gravity and water erodes earth.
The gravity of Charon is about 3% that of Earth.
Earth will always have gravity for gravity is a result of mass.

Earth's gravity is 1g.
