Rock Cycle

• Why are rocks considered important in our world?


  They comprise mountains and infrastructures like houses and roads
• What geological processes cause changes in rocks?


  Weathering, erosion, volcanic eruption, and movement of plates
• What does the rock cycle represent?


  • The unending journey and transformation of rocks
  • Changes in rock types through geological processes
• What are the three major types of rocks in the rock cycle?

  Igneous, sedimentary, and metamorphic rocks
• How does a metamorphic rock become an igneous rock?


  By melting into magma and then cooling down
• What is the term for igneous rock formed below the ground?


  Intrusive igneous rock
• What is the term for igneous rock formed at the Earth's surface?


  Extrusive igneous rock
• What happens to outcrops through the process of weathering?


  They are broken down into smaller pieces forming regolith
• What are sediments?


  Materials that are moved and deposited in new locations
• How do sediments turn into sedimentary rock?


  Through burial, compaction, and cementation
• What occurs when a sedimentary rock is buried at greater depth?

  It undergoes metamorphism and turns into metamorphic rock
• What do the inner arrows in the rock cycle diagram indicate?


  That igneous and metamorphic rocks can also become metamorphic rocks
• What does the presence of arrows from sedimentary and metamorphic rocks to outcrop imply?


  That these rocks can be uplifted to become outcrops
