What is a clastic sedimentary rock?

To determine

A clastic sedimentary rock.

Answer to Problem 17RQ

The rocks made up of small pieces of weathered rock, shell debris and solid organic matter are called clastic sedimentary rocks.

Explanation of Solution

Sedimentary rocks are formed when sediments come in suspension due to the effect of weathering. When these suspended sediments flow with air, or water from one place to another, they get collected. When the rocks formed are made of small pieces of weathered material, then the rocks are called clastic sedimentary rocks. These rocks are categorised by the size of the particle. They range from a very small size to large size. The common types of clastic sedimentary rocks are shale and sandstone.

Conclusion:

Therefore, the rocks made up of small pieces of weathered rock, shell debris and solid organic matter are called clastic sedimentary rocks.
