How do calcareous oozes form?
O the particles are precipitated by bottom-dwelling organisms
O the particles are precipitated in the water column below the depth of sunlight penetration and then sink to the bottom
O the particles are precipitated in warm, surface waters and sink to the bottom as biogenous sediments
O the particles settle out from calcite-rich turbidity currents at depths greater than 15,000 feet

Answer:

the particles are precipitated by bottom-dwelling organisms

Explanation:

  • The calcareous ooze is formed by the 30% of the microscopic shells that a known as the tests and are formed by the foraminifera, coccolithophores, and pteropods, which are most common sediments on the seafloor by area and cover about 50 % of the oceanic floor.  And can be converted to stone by the process of compaction and cementation and re-crystallization.
