To solve this rock cycle activity, we need to connect the rocks and materials (like magma and sediment) using the correct processes. The rock cycle shows how rocks change from one type to another over time.
Here is the step-by-step logic to connect them:
1.
Magma to Igneous Rock:
* Magma is hot, melted rock. When it cools down, it hardens into solid rock.
*
Process: COOLING
*
Connection: Magma → Igneous Rock
2.
Igneous Rock to Sediment:
* Any rock sitting on the surface gets broken down by wind, rain, and ice. This creates small pieces called sediment.
*
Process: WEATHERING AND EROSION
*
Connection: Igneous Rock → Sediment
3.
Sediment to Sedimentary Rock:
* Layers of sediment pile up. The weight presses them together (compaction), and minerals glue them together (cementation).
*
Process: COMPACTION AND CEMENTATION
*
Connection: Sediment → Sedimentary Rock
4.
Sedimentary Rock to Metamorphic Rock:
* If sedimentary rock gets buried deep underground, it gets very hot and squeezed by heavy pressure. It changes shape but doesn't melt.
*
Process: HEAT AND PRESSURE
*
Connection: Sedimentary Rock → Metamorphic Rock
5.
Metamorphic Rock to Magma:
* If the metamorphic rock gets even hotter, it eventually melts completely and turns back into liquid magma.
*
Process: MELTING
*
Connection: Metamorphic Rock → Magma
*(Note: There are other shortcuts in the cycle too! For example, Igneous or Metamorphic rocks can also melt directly into Magma, or turn into Sediment through weathering. But the steps above create the main circle.)*
Final Answer:
The Rock Cycle Connections:
*
Magma → (COOLING) →
Igneous Rock
*
Igneous Rock → (WEATHERING AND EROSION) →
Sediment
*
Sediment → (COMPACTION AND CEMENTATION) →
Sedimentary Rock
*
Sedimentary Rock → (HEAT AND PRESSURE) →
Metamorphic Rock
*
Metamorphic Rock → (MELTING) →
Magma
