What is the difference between terrigenous and pelagic deposits?

Terrigenous Deposits

Pelagic Deposits

The main sources of Terrigenous deposits are terrestrial sediments. 

Pelagic deposits can consist of organic material in the form of marine plants and animals as well as inorganic material.

They are mainly found on the Continental shelf.

They are generally found in the deep oceans in the continental slope, continental rise, trenches, and abyssal plains.

Boulders, sand, gravel, rocks, and mud are major components of these deposits.

They cover about 75.5 per cent of ocean areas in the form of many types of oozes.
