What do these two changes have in common? cutting an apple breaking a rock in half

[ "Both are caused by heating.", "Both are only physical changes.", "Both are chemical changes.", "Both are caused by cooling." ]

B

Step 1: Think about each change. Cutting an apple is a physical change. The apple gets a different shape. But it is still made of the same type of matter as the uncut apple. Breaking a rock in half is a physical change. The rock gets broken into two pieces. But the pieces are still made of the same type of matter as the original rock. Step 2: Look at each answer choice. Both are only physical changes. Both changes are physical changes. No new matter is created. Both are chemical changes. Both changes are physical changes. They are not chemical changes. Both are caused by heating. Neither change is caused by heating. Both are caused by cooling. Neither change is caused by cooling.
