A)less than 30% biogenous material.
B)more than 30% biogenous material.

D)less than 30% neritic material.
E)more than 30% neritic material.

Question

Quizplus · Accepted Answer

Pelagic clay is formed from the accumulation of fine-grained particles that settle through the water column, mainly consisting of siliceous and clay minerals. These particles come from various sources, including biogenous material (such as the tests of microscopic planktonic organisms), hydrogenous material (such as minerals precipitated from seawater), and neritic material (such as riverine, glacial, or wind-blown sediments). However, pelagic clay usually contains less than 30% biogenous material, making choice A the best answer.
