Because you are just breaking it into smaller pieces. The rock's chemical make up is not being changed.

What is crushing a rock a chemical or a physical change?
Crushing a rock is a physical change. It is still rock, just in smaller bits.
When molten rock cools and hardens is a physical change or chemical change?
When molten rock cools and hardens, it is a physical change because the composition of the rock remains the same. The change in state from liquid to solid does not alter the chemical makeup of the rock.
Is crushing a rock chemical or physical change?
Grinding something is an example of a physical change, because you are not chemically changing what the substance is, you are only changing the form of it. Another example of a physical change is boiling water, because the water is still water, it's just in a gas form instead of liquid.When something is grinded it is a physical change not a chemical change.
Is rock broken into small pieces a chemical change?
No actually it isn't. Breaking a bone is a physical change. Think about it. Are you changing it into a different substance. No you're not, so it's a physical change.

Is a rock getting melted into magma a chemical reaction?
No, the process of a rock melting into magma is a physical change, not a chemical reaction. The change is due to an increase in temperature causing the rock to undergo a phase change from solid to liquid.
What physical change in metamorphic rock signals the end of metamorphism?
from what i know there is no physical change that signals the end of metamorphism but there is a physical change during the process of metamorphism. during metamorphism the shape of the rock changes due to force of stress this is a physical change. (a physical change is when the shape or composition ofa substance e.g. rock has changed). by the way i am only 12
What is an example of a physical change to a rock that can happen quickly?

Is landslide physical or chemical change?
Physical. It is still dirt/rock, no change to it's nature- just its position.
Type of change that happens when you break a rock or freeze water?
Physical change: breaking a rock changes its physical appearance without altering its chemical composition. Freezing water involves a physical change where the water molecules rearrange to form a solid structure, without any change in the chemical composition of water.
Why is throwing rocks a physical change?
Throwing rocks is considered a physical change because no new substances are created during the process. The rock remains a rock even after it has been thrown. The change is only in the position and location of the rock, not in its chemical composition.
