The answer is stress
pressure
Pressure
compression
gravity
If you sit on a rock with a downward force of 'W' pounds, then the rock exerts an upward force of 'W' pounds on your derriere. We know that the sum of the forces on the seat of your pants must be zero. Otherwise the pants would be accelerating, either up or down.
Acid rain___No, rain isn't a force in and of itself, even if it is acidic. A force by definition must be able to make an object accelerate. Gravity is a force. Magnetism is also a force that might act upon a rock, depending on its elemental makeup. Friction is a force that might slow the effects of the other two (a negative acceleration).
-- The force of gravity of your bottom against the rock, in the downward direction. -- The 'reaction' force of the rock against your bottom, in the upward direction. Since the forces are equal in magnitude and opposite in direction, their vector sum is zero. Some would describe this situation as "The forces on your bottom are balanced." In any case, the 'net' force on your bottom is zero, and your bottom therefore does not accelerate.
If no force (gravity, friction, or any other force) acts on an object, it will continue moving indefinitely, without changing its velocity (i.e., speed and direction).
the force that acts on rock to change its shape or volume is stress.
it is the mesosphere
Pressure and/or Heat act on a rock to change it
A force that acts on rock to change its shape or volume called stress. Tension is the stress that sketched rock so that is becomes thinner in the middle.

Erosion
It breaks apart

Inertia, and Newton's First Law.
Only gravity (however, it is smaller - it's not 9.8 m/s^2).
No, dense rock does not have low gravity. Gravity is a fundamental force that acts on all objects with mass. The density of a rock refers to its mass per unit volume, but it does not affect the force of gravity acting on it.
