These are called minerals. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystal structure. They are the building blocks of rocks and cannot be broken down into simpler substances by physical or mechanical means.
It is physical. The tooth is broken into smaller pieces, but the pieces are still made of the same substances.
Elements can be broken down into smaller pieces: a compounds smallest particle is a molecule
Physical digestion occurs as food is broken down into smaller pieces through chewing and the mixing action of the stomach muscles. This process increases the surface area of the food, making it easier for digestive enzymes to break down the nutrients.
Small pieces of rock from old broken-up comets become meteoroids when they enter Earth's atmosphere. Depending on their size, they can create meteors (shooting stars) as they burn up or meteorites if they survive the journey to the surface of the Earth.

Rubble refers to broken or fragmented pieces of stones, bricks, concrete, or other debris left over from a building or structure that has been destroyed or demolished. It can also be used to describe the remains of rock or other material that has been crushed or broken into smaller pieces.

metoeroids
In most cases yes.
Wearing is the process where a rock is dissolved and worn away or broken down into smaller and smaller pieces
mechanical weathering
So we can get the energy
Boulders broken down by weathering or erosion can form smaller pieces called pebbles or gravel. These smaller pieces can eventually be further weathered into sand particles.
i would describe it as the shape of a rock been broken down into pieces
So we can get the energy
