Types of Rock and the Rock Cycle

Learn about the three major types of rock - igneous, sedimentary, and metamorphic - and how they can transform into one another through geologic activity. Explore the origin, history, structure, and forces that shape the solid earth.

  1. Chapter 10 Rocks

  2. Chapter 10 Section 1: Rocks and the Rock Cycle EQ: Describe the three types of rock.

  3. 10.1 Rocks and the Rock Cycle • Magma is the parent material for all rocks. • Once the magma cools and hardens, many changes can occur. • Geology: the study of the origin, history, structure, and the forces that shape the solid earth.

  4. 3 Major Types of Rock • Igneous • Sedimentary • Metamorphic

  5. Igneous Rock • Formed when magma cools and hardens • Igneous means “from fire” in Latin

  6. Sedimentary Rock • Rock, minerals, and organic matter that have been broken down into fragments known as sediment. • When sediment deposits harden after being compressed or cemented together, they form sedimentary rock.

  7. Metamorphic Rock • Certain forces and processes can change rock into another form. • Tremendous pressure, extreme heat, and chemical processes can create metamorphic rock.

  8. The Rock Cycle • Any of the 3 types of rock can be changed into any other type by geologic activity. • This series of changes is called the rock cycle. • (See page 177 for a good illustration.)

  9. Review #1 • Which major type of rock forms from magma that cools and hardens? • igneous

  10. Review #2 • Which type of rock is composed of fragments cemented together? • sedimentary

  11. Review #3 • Which type of rock forms as a result of intense heat, pressure, or chemical processes? • metamorphic

  12. Review #4 • What is the rock cycle? • The series of changes brought about by geologic forces and processes in which rock changes from one type to another and back again.
