Question

What kind of rocks are formed by the precipitation of calcium carbonate (CaCO3) from sea water? Select all that apply.

Answer 1

Shale, and Sandstone are the rocks formed by precipitation of calcium carbonate from sea water.

Option B and D

Explanation:

Calcium carbonate can get precipitated from sea water and it forms rocks termed as limestones. These limestones are a variety of sedimentary rocks. Along with it, shale and sandstones are also varieties of sedimentary rocks and they also contain some of the precipitation of calcium carbonate.

The composition of sandstones consists of quartz and feldspar along with some of the composition of calcium carbonate. The same concept goes for Shale also. Basically, Shale is a mixuture of Clay but they can combine with limestone.

Thus, Shale, Sandstone and limestones are the rocks formed by precipitation of calcium carbonate from sea water.
