To solve this problem, we need to match the geological processes listed on the right with the numbered arrows in the rock cycle diagram. Let's look at what each number represents based on how rocks change.
Step 1: Analyze Arrow #1
*
Observation: The arrows labeled
1 point from Igneous, Sedimentary, and Metamorphic rocks toward "Sediments."
*
Process: When any type of rock is broken down by wind, water, or ice into smaller pieces (sediments), that process is called weathering and erosion.
*
Match: 1 = Weathering and Erosion
Step 2: Analyze Arrow #2
*
Observation: The arrow labeled
2 points from "Magma" to "Igneous" rock.
*
Process: Magma is hot, melted rock. When it cools down and hardens, it becomes solid igneous rock.
*
Match: 2 = Cooling
Step 3: Analyze Arrow #3
*
Observation: The arrows labeled
3 point from Igneous, Sedimentary, and Metamorphic rocks toward "Magma."
*
Process: For solid rock to turn back into liquid magma, it must get extremely hot and melt.
*
Match: 3 = Melting
Step 4: Analyze Arrow #4
*
Observation: The arrows labeled
4 point from Igneous and Sedimentary rocks toward "Metamorphic" rock.
*
Process: Metamorphic rocks are formed when existing rocks are buried deep underground where they are squeezed and heated. They don't melt, but they change shape and texture due to heat and pressure.
*
Match: 4 = Heat and Pressure
Step 5: Analyze Arrow #5
*
Observation: The arrows labeled
5 point from "Sediments" to "Sedimentary" rock.
*
Process: Loose sediments (like sand or mud) eventually get pressed together tightly and glued by minerals to become solid rock. This pressing and gluing is called compaction and cementation.
*
Match: 5 = Compacting and Cementation
──────────────────────────────────────
Final Answer:
1 — Weathering and Erosion
2 — Cooling
3 — Melting
4 — Heat and Pressure
5 — Compacting and Cementation
