1. Gravity - it keeps objects from getting away from Earth into space.
2. Friction - in most places there's friction which keeps objects from sliding all over Earth.
Gravity.
The Earth's gravitation.
In principle, yes; but please note that:* There is no such thing as an "absolute velocity". You need to specify that it has zero velocity with respect to some other object. In other words, that it should move at the same velocity as that other object. As Earth, for example.* An object won't stay at such a relative velocity of zero for long. Forces, and mainly gravitational forces, will soon change its velocity. For instance, if you have a spacecraft that is in orbit around Earth, and you make it halt, it will fall straight down. (In this case, it is precisely its speed that keeps it in orbit.)
Although gravity is pulling it in, inertia is "pulling it out". Thus, both forces cancel, and we are left with a moon in orbit.
Gravity keeps you on the earth.....
hydrostatic
No force orbits around the Earth. Forces do not orbit. The force that keeps material objects in orbit around the Earth is the mutual force of gravity between the Earth and the object.
The type of force that keeps an object such as the Earth moving in a circle is a combination of gravity and centrifugal force. Gravity wants to pull the object inward, but centrifugal force wants to push the object outward. This combination keeps objects going in a circular path. You could also say that, for objects such as a rock attached to a rope that is swung in circles, the forces are the tension of the rope opposing centrifugal force. This is essentially the same thing, except with different forces at work.
Yes, balanced forces will keep an object at rest.

That would be GRAVITY
The Earth's gravitation.
upthrust keeps the object floating the gravitational pull keeps it along the meniscus of the averaged water
Gravity keeps your feet on the ground. It is also what keeps every living and non living thing attached to the earth.
Gravity and Inertia. The gravity keeps the planet, moon etc. going in a circle and inertia keeps it going (inertia is the tendency of a moving object to continue in a straight line or a stationary object to remain in place. If there was no gravity the planet, moon etc. would just go in a straight line but with gravity it pulls it in a circle like a string attached to an object at the center.
Tidal forces cause the moon to be in a 1 to 1 resonance with the earth.
No one does. The gravitational forces between it and the Earth are responsible for maintaining the orbit.
The force of gravity keeps the Earth (and all the other planets) orbiting the Sun.
