Rock Cycle Formation Processes

Understanding How Rocks Transform Grade 6 Science 45-minute lesson

Three Types of Rocks

Igneous rocks form from cooling magma or lava Sedimentary rocks form through compaction and cementation Metamorphic rocks form from heat and pressure

The Rock Cycle Diagram

Formation Processes Comparison

{"left":"Igneous: Cooling and hardening of magma or lava\nSedimentary: Compaction and cementation of particles\nMetamorphic: Extreme heat and pressure transformation","right":"All processes occur over long periods of time\nTemperature and pressure are key factors\nEach process creates distinct rock characteristics"}

Rock Detective Challenge

Sample A: Formed through compaction - What type? Sample B: Extreme heat and pressure - What type? Sample C: Melting and cooling - What type? Sample D: Accumulation of sediment - What type?

Critical Thinking: Rock Transformations

What processes turn sedimentary rock into metamorphic rock? How can metamorphic rock become igneous rock? Why do rocks need different conditions to transform?
