identifying sedimentary rock types\nwhich rock is a clastic rock?

Brief Explanations:

Clastic rocks form from weathered rock fragments cemented together. They exhibit碎屑 (clastic) texture with visible grains or particles. The first rock shows fossil and granular structure, typical of clastic sedimentary rocks like shale or sandstone. The second rock has a crystalline structure, more indicative of non-clastic (e.g., chemical or metamorphic) rocks. The third rock displays coarse, rounded clasts in a matrix, characteristic of clastic rocks like conglomerate. Both the first and third rocks are clastic, but based on typical textbook examples, conglomerate (third image) is a classic clastic rock type.

Answer:

The third rock (right image) is a clastic rock.
