Question

answer questions about rocks and the rock cycle question 3 of 15 what element is missing from this diagram of the rock cycle? a magma b cooling c weathering and erosion d igneous rock the rock cycle

Explanation:

In the rock - cycle, magma cools to form igneous rock. Igneous rock can be broken down by weathering and erosion to form sediments. Sediments can be compacted and cemented to form sedimentary rock. Sedimentary rock and igneous rock can be transformed into metamorphic rock under heat and pressure. Metamorphic rock can melt to form magma again. The given options list magma, cooling, weathering and erosion, and igneous rock. The missing element from a complete description of the rock - cycle among these is sedimentation (the process of sediments forming sedimentary rock), but among the given options, the rock - cycle step that is not fully represented in the diagram's description is weathering and erosion which is crucial for the transition from igneous rock to sediment.

Answer:

C. Cooling
