There's no theoretical minimum to size, except that you need to have more than a single molecule to call it a "rock". The smallest bits would thus be on the order of nanometers.
Um kind of. I am not sure of what you mean by "space rock" but yes, I guess. An asteroid is bits of rock that did not form a planet found in a belt between Mars and Jupiter! I hope this helped!
Because the gas is in a clump and bits of space rock stick onto the gas and creates something like a shield. Then the bits of space rock on the gas stick together. The clump of rock over time, gets smooth and then it is big enough to be a planet.
Bits of rock from outer space entering our atmosphere.
Planetoids are made of usually what planets are made of. This includes bits of rock, space dust, or even ice.
rocks found in the bottom of the ocean or sea.
Meteorite
No. They are just bits of ice, dust or rock floating through space that then enter Earth's atmosphere and start to burn up, giving us the chance of seeing it. They are not like the planets that have rings.No. They are just bits of ice, dust or rock floating through space that then enter Earth's atmosphere and start to burn up, giving us the chance of seeing it.

Rock.
The smallest rock in our solar system is nothing but asteroids.
sediments
If existing bits of rock become attached through the process of lithification, a clastic sedimentary rock is formed.
They can be moved by the rain coming down and landing on the rock so the rock brakes and crumbles off.Also it can be caused by the wind blowing on the rock and bits can fall off the rocks.
