Question

The chemical binder for many sedimentary rocks, such as limestone, is ________?

1) phosphorous
2) boron
3) calcium carbonate
4) basalt
5) nitrogen

Answer 1

The chemical binder for sedimentary rocks like limestone is calcium carbonate.

Step-by-step explanation:

The chemical binder for many sedimentary rocks, such as limestone, is calcium carbonate. Sedimentary rocks can form through chemical processes, and limestone is a type of chemical sedimentary rock. It forms when calcium carbonate precipitates out of water and accumulates over time, eventually forming solid rock.
