What is the rock cycle?

1. Observe: A cycle is a path with the same start and end. Create a rock cycle with the Gizmo.

A. Click Magma. How hot is magma? It 1000 degrees Celsius

B.Click Crystallization (below ground). What kind of rock is formed when magma cools below the surface? Igneous rock
C. Click Exposure and weathering. What forms when rocks break down? It soilD. Click Erosion and deposition. In what ways are sediments transported? It sediment
E. Click Lithification and compaction. (Lithification is hardening into rock.) What kind of rock isformed from sediments? Sedimentary rock
F. Click Increase temp. And pressure. What kind of rock is formed? Metamorphic rock

G. Click Melt. What is formed when rocks melt deep underground?magma

2. Describe: Select the PATH tab. What are the steps in this rock cycle? Magma crystallization bellow the grown igneous rock soil it sediment Sedimentary rock metamorphic rock magma

3. Onyour own: On the SIMULATION tab, click Start again. In the spaces below, list three rock cycles. You can start anywhere, but each cycle must begin and end at the same point.

Cycle 1: metamorphicrock, exposure and weathering, soil, erosion and deposition, sediments, lithification and compaction, sedimentary rocks, increase temp and pleasure metamorphic rock

Cycle 2: magma,crystallization above ground, extrusive igneous rock, exposure and weathering, soil, erosion and deposition, sediments, lithification and compaction, sedimentary rock, increase temp and pressure, melts magmaCycle 3: magma, crystallization below the ground, extrusive igneous rock, increase temp and pressure, metamorphic rock, melt magma

4. Diagram: The image below summarizes the different stations in the rock cycle. Draw an arrow to represent each possible transition from one rock type to another. Then label each arrow...
