Correct. The two parts of the correlative conjunction
either . . . or are followed by similar grammatical forms, the prepositional phrases
under the coastal land and
beneath the ocean floor.
For more help, see section
S1.
Sorry. The two parts of the correlative conjunction
either . . . or should be followed by similar grammatical forms. In this case,
either is followed by a verb and a prepositional phrase, but
or is followed only by a prepositional phrase. Moving the word
either directly before the first prepositional phrase makes the two parts parallel.

Correct. The two parts of the correlative conjunction
not only . . . but also are followed by prepositional phrases:
