1. Label the Diagram:
- Top left box: Igneous Rock
- Top right box: Sedimentary Rock
- Bottom left box: Metamorphic Rock
- Bottom center box: Melting
- Bottom right box: Crystallization
2. Which processes are powered by Earth’s surface processes (like wind, water, ice)? Weathering and Sedimentation. These occur at or near Earth’s surface and are driven by external forces like erosion and deposition.
3. Several processes in the rock cycle are powered by Earth’s internal heat. Where does the energy for these processes ultimately come from? The energy comes from radioactive decay of elements in Earth’s mantle and core, as well as residual heat from Earth’s formation. This internal heat drives melting, metamorphism, and tectonic activity that move rocks through the cycle.
