It's not. Many people thought that the Earth's inner core was liquid because of the intense heat that is generated by the remains of the Earth's creation and the radiation emitted from radioactive decay. Of course, now we think, due to the behavior of seismic waves and a number of other evidences, that the Earth's inner core is solid due to the intense pressure that exists.
The largest force that keeps the Earth circling the sun is gravity. Gravity is the force of attraction between the Earth and the sun that keeps the Earth in its orbit.
Electrostatic force between the electron and the positively charged nucleus.
The inner core of the Earth has a temperature higher than its melting point. Despite being made of solid iron and nickel, the immense pressure at the center of the Earth keeps it in a solid state even at temperatures above its melting point.
That's gravity. Near the surface air has a density of about 1.2Kg/m^3. Air isn't that lightweight as you might think. We usually just don't lift it, but push it away, which is much easier.
The Earth's gravitational field pulls objects towards its center, creating the force of gravity that keeps everything on the surface of the Earth and governs the motion of celestial bodies in space. The strength of gravity decreases with distance from the Earth's surface according to the inverse square law.
Nothing keeps them from being pulled. Earth's gravity certainly pulls on them.
Friction has 100% nothing to do this the Earths orbit, its gravity and inertia.
The force that keeps the Moon in orbit around Earth is gravity. Gravity is the force of attraction between two objects with mass, and it is what keeps celestial bodies like the Moon in orbit around larger bodies like the Earth.
I believe your answer would be gravity. You are always being pulled by the Earths gravitational force, and it is what keeps your feet on the ground, and fall down if you are not conected to something.

The weight of the displaced liquid is equal to the buoyant force acting on the body. This is known as Archimedes' principle, which states that the buoyant force experienced by an object immersed in a fluid is equal to the weight of the fluid displaced by the object.
Actually, it's the gravity of the sun that keeps the planets in orbit around it. The force of gravity between the sun and the planets causes them to be pulled towards the sun, while their momentum keeps them moving in a circular or elliptical path.
In physics, buoyancy is the upward force that keeps things afloat. The net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body. This force enables the object to float or at least seem lighter.
The force that keeps all of our planets in rotation is gravity.
The Earth's gravitation force is greater than the Moon, which keeps the Moon in orbit round the Earth.
The upward force is called buoyancy. It is the result of the pressure difference in a fluid between the top and bottom of an object. The buoyant force is equal to the weight of the fluid displaced by the object.
