Question

coquina is a rock made of small pieces of broken shells. ocean waves break seashells into smaller pieces. over time, these pieces are moved and deposited. when they stick together, they form coquina. coquina is most likely a(n) ______ rock. choose one option a igneous b sedimentary c metamorphic

Explanation:

Sedimentary rocks form from the accumulation, deposition, and cementation of sediment (like broken shell pieces here) over time. Igneous rocks form from cooled magma/lava, and metamorphic rocks from existing rocks changed by heat/pressure. Coquina's formation (shell pieces deposited, stuck together) matches sedimentary rock formation.

Answer:

B. sedimentary
