10.2 Introduction Rock Cycle, Formation processes
The Rock Cycle: How Earth Continuously Creates and Transforms Rocks
Discover how igneous, sedimentary, and metamorphic rocks form and transform through Earth's continuous geological processes.
What You'll Learn
The rock cycle continuously transforms rocks among three main types.
Igneous rocks form when magma or lava cools and solidifies completely.
Sedimentary rocks form through compaction and cementation of sediments.
Heat and pressure transform existing rocks into metamorphic rock types.
What You'll Practice
1
Students identify rock types and the processes that form each.
2
Questions test understanding of lithification, weathering, and erosion processes.
3
Learners trace rock cycle pathways from sedimentary through igneous formation.
Why This Matters
Understanding the rock cycle reveals how Earth continuously recycles its materials, forming the natural resources and geological features that shape our world.
