Because it gets rotten.
Oxidisation. Same as metal getting rusty. It reacts with the oxygen in the air and becomes brown.
There is an enzyme called polyphenol oxidase contained in the apple. when explosed to air it reacts with oxygen and iron containing phenols and oxidizes. this is what causes the rust brown color.
