The physical structure of the Earth's rocks is changed by geological processes such as weathering, erosion, and sedimentation, as well as tectonic activities like folding, faulting, and volcanic eruptions. These processes can alter rock composition, texture, and structure over time, leading to the formation of different rock types, such as sedimentary, metamorphic, and igneous rocks. Additionally, human activities, such as mining and construction, can also impact the physical structure of rocks.

When a sculptor uses a chisel on a rock, the rock undergoes physical change. The chisel physically alters the shape and structure of the rock to create the desired sculpture.
When sedimentary rock is changed by heat and pressure, it forms metamorphic rock. This process, known as metamorphism, alters the mineral composition, texture, and structure of the original sedimentary rock. Some common examples of metamorphic rocks formed from sedimentary rocks include marble from limestone and slate from shale.
Molton rock that flows from a volcano onto Earths surface is
Quartizite is a metemorphic rock that is either regional or contact. It is made when lava rises to the earths crust, and heats the sedimentatry rock around it.
Physical samples of rock extracted (taken) from deep within Earths crust.
Smaller particles of rock are produced from larger particles.

Physical is when a rock or something changes its shape and not structure. Chemical is when a rock or something changes its entire format like a shape and structure.

Because you are just breaking it into smaller pieces. The rock's chemical make up is not being changed.
In geology, it is the process of change that takes place in the physical structure of a rock due to heat and/or pressure. A metamorphic rock is an igneous, sedimentary, or another metamorphic rock that has either been squeezed by incredible pressures deep underground and/or has been exposed to very high temperatures, altering its structure, mineral alignment, mineralogy, and possibly its chemistry.
Actually, it is a physical change because when sugar and water mix together, they are not forming a new substance, sugar dissolves, but it doesn't disappear. So when you crystallize it, it still has the same chemical structure, the only thing that changed is the physical appearance.
