Alright...
What are the differences between neritic and pelagic sediments? Where is each one found?

Neritic sediments are found near shore (On the continental shelf), while pelagic sediments tend to be found out in the deeper ocean (In the abyssal plains). One difference could be that almost all neritic sediments are lithogenous, and pelagic sediments can also be biogenous, as a result of Calcareous and Sillicious organisms dying and depositing on the bottom.

That looks good to me! Your turn?

iirc its just when magnetic reversals are inhibited, so ig areas where theres lower crustal magnetization

Sort of correct. It's where the rock near hydrothermal vents has been eroded, thus inhibiting the magnetic reversals. Your turn!

Explain the purpose of a breakwater, and how it works.

The breakwater is meant to protect coasts from erosion from longshore currents. They stick out into the water and like absorb energy of the waves that strike them, shielding the coast.

Explain what the calcium compensation depth is. How does this vary with temperature?
