When an apple is injured (or cut into pieces), the plant tissue is exposed to oxygen. This triggers an enzyme known as polyphenol oxidase (PPO) to—wait for it—oxidize polyphenols in the apple's flesh. This results in new chemicals (o-quinones), which then react with amino acids to produce brown-colored melanins.
So this is due to chemical change.
