Final answer:
Neritic sediments are most likely composed of sand, silt, and gravel that accumulate on the ocean floor in the continental shelf area. They are derived from land erosion and transported by rivers before being deposited in the ocean.
Step-by-step explanation:
Neritic sediments are most likely to be composed of sand, silt, and gravel. Neritic sediments refer to the loose particles that accumulate on the ocean floor in the continental shelf area, which is relatively shallow. These sediments are typically derived from land erosion, transported by rivers, and then deposited in the ocean. Examples of neritic sediments include sandstone and mudstone with wavy bedding and ripple marks.
