Where can you find the name of certain rocks?
If you don't know what type of rock they are, type either sedimentary, igneous, or metamorphic on a search site and see which one looks most like the rocks that you have.
Metamorphic rocks can be found on the surface in the highly eroded features of old mountains, in upwardly thrust exposures at certain beach areas, and in glacial drift they can be found as erratics, rocks that are not native to an area. Metamorphic Rocks can be found in the Earth's crust. In fact, a lot of Earth's crust is made up of metamorphic rocks. Metamorphic rocks are the rarest of the three types.(Sedimentary,Igneous, Metamorphic)
