Question

the diagram below is a model of the rock cycle. the diagram shows how one type of rock can change into another type of rock. select the sedimentary rock.

Explanation:

Sedimentary rocks form from sedimentation (deposition of sediments) after weathering and erosion break down other rocks. The rock with the layered, stacked appearance (the top - most rock in the diagram) is associated with sedimentation (the arrow labeled "sedimentation" points to it, and it also has "weathering and erosion" leading from it, which is consistent with sedimentary rock formation: sedimentary rocks can be weathered and eroded to form sediments again). The other rock types: the molten material is magma, the crystalline - looking rock is likely igneous (formed from crystallization of magma), and the single - looking rock could be metamorphic (formed from metamorphism) or igneous, but the layered one fits sedimentary rock formation via sedimentation.

Answer:

The sedimentary rock is the layered, stacked - looking rock (the top - most rock in the diagram with the "sedimentation" arrow pointing to it and "weathering and erosion" arrow coming from it).
