A river washes sediment into the ocean. The sediment is composed of plankton and very fine particles of weathered silicate rock smaller than 0.05 mm in size. The material drifts down slowly through the deep, quiet water and collects on the sea floor. If buried, what type of rock will this sedimentary deposit most likely become?


a. Tufa
b. Shale
c. Conglomerate
d. Sandstone

Respuesta :

Answer:

Option (A)

Explanation:

Tufa is a sedimentary limestone rock which is primarily comprised of calcium carbonate (CaCO₃). It is pore spaces in it. It is primarily formed from the precipitation of calcite, either chemically or biologically, which are derived frm the surface water or the ground water.

This type of sedimentary rock is formed from the deposition of materials or sediments that are carried by the rivers into the deeper zone of ocean, and after compaction and lithification, forms the rock called 'Tufa'.

Thus, the correct answer is option (A).
