 D)iron-rich continental plate material was being pulled into the ocean by Earth's magnetic field

Answer to Question 1

C

Answer to Question 2

Yes, it would be surprising to find sand on the seafloor. Because sand is relatively large, it requires more energy to transport. However, as distance from the shoreline increases, transport energy decreases, and only the finest particles, like silts and clays, are able to be carried.
