Yes, crushing rocks is considered a physical change because the rocks are broken down into smaller pieces without changing their chemical composition. This process can be reversed by reassembling the pieces back together.
Writing with a pencil is an example of what friction?
Writing with a pencil is an example of kinetic friction. This type of friction occurs between two surfaces in relative motion, such as the pencil tip and the paper, which creates heat and wears down the pencil lead over time.

Is breaking pencil a chemical change?
Sharpening a pencil is a physical change, because there is no change to the chemical makeup of the pencil when sharpening it. It is simply chunks of wood being sliced off to reveal more of the lead.It is a physical change.
What gets created by the physical processes that change Earths surface by pushing its crust up or wearing it down?
Water
Why sharpening a pencil is a different type of physical change than freezing water to make ice cubs?
Although they both still have the same basic elements (i.e. pencil and lead vs water), there is a physical state change that occurs when you freeze water to make ice. Sharpening/shaving down a pencil only results in a difference of shape and size. It's about the same as ripping paper vs burning paper. Also, freezing water to make ice is a reversible change (you can melt ice to turn it back into water) and shaving a pencil is an irreversible change (you can't sharpen a pencil and then put the pencil shavings back onto the pencil.)
What gets created by the physical process that change earth's surface by pushing its crust up or wearing it down?
Mountains are created by the physical process of pushing the Earth's crust up, while valleys and canyons are formed by the process of wearing down the crust through erosion.
