Question

What happens to radiolarians after they die? What is marine ooze?

Answer 1

Answer:

When radiolarians die, their tests usually sink and accumulate on the ocean floor in biogenic sediments. Contributing to the pelagic oozes that date back millions of years, the ancient radiolaria skeletons are often useful in geological dating experiments, climatological studies, and oil exploration.

Ooze, pelagic (deep-sea) sediment of which at least 30 percent is composed of the skeletal remains of microscopic floating organisms. Oozes are basically deposits of soft mud on the ocean floor.
