Why is continental crust generally much older that oceanic crust?

One aspect and way that I always learned was the sense the oceanic crust would be covered in non-stop water, this would then mean that to crust would be so fresh, it wouldn't have time for the sun and the wind, and the extreme rain to be poured on it for the crust to be ruined. But, as we talking about the continental crust, this would be the complete opposite of the oceanic. Therefore, we would then understand that they would practically live in different environments.

This is what i found on google“ the monomers combine with each other via covalent bonds to form larger molecules known as polymers. in doing so, monomers release water molecules as byproducts. this type of reaction is known as dehydration synthesis, which means “to put together while losing water. in the process, a water molecule is formed.” i hope this you
