Since the Earth is rotating, and moving through space, and the rock is moving along with the Earth, then it does, but relative to the Earth, I'd say that the momentum of the rock (mass * velocity) is essentially zero.

It is called a crevasse.
it is called meteorite
Electrons are very small, and have very small mass, but they are not visible light (photons).
Matter
A meteoroid is a small mass of something moving through space. A meteorite is defined as a piece of such that actually lands on Earth.
If you measure the mass of a movjng object as it moves through your laboratory, you'll always find that it has more mass than it had when it was just sitting on the shelf. The faster it's moving through your laboratory, the greater its mass will be. It doesn't matter whether it's accelerating or not.

Density
Albert Einstein. He argued that what we think of as "gravity" could be the influence of mass moving through some as-yet-undetected 4th-dimensional curving of space.
The amount of space occupied by a body is called its volume. Mass is the amount of metter in a body whereas volume is the amount of space a body occupies.
