diatom shells settle on the ocean floor from the surface
you can find the youngest rocks on the top of the ocean floor.

Yes, in many places it is. But like the surface of the earth that you can see, the ocean floor has many different topographies. The ocean floor has mountains, volcanoes, deep valleys, and reefs.

No corals live on the ocean floor, they live in shallow seas, i.e. near contiental shelves, or coral atolls like in Hawai'i were the islands have eroded just below sea level where shallow warm waters are prime for coral growth.
