4. Diagram: The image below summarizes the different stations in the rock cycle. Draw an arrow to represent each possible transition from one rock type to another. Then label each arrow with the process that occurs, such as “weathering” or “erosion and deposition.”

D. Sedimentary rock  sediment: __________________________________________

Answer 1

A. Intrusive igneous rock → sedimentary rock: Weathering and erosion break down the intrusive igneous rock into sediment. The sediment is then transported and deposited, undergoing compaction and cementation to form sedimentary rock.

B. Metamorphic rock → sediment: Weathering and erosion break down the metamorphic rock into sediment. The sediment is then transported and deposited.

C. Sediment → sedimentary rock: Compaction and cementation occur, causing the sediment to become compacted and bind together to form sedimentary rock.

D. Sedimentary rock → sediment: Weathering and erosion break down the sedimentary rock into sediment.
