Types of Rock

Science · Volcanoes & Earthquakes · conceptual

Know the three main types of rock — igneous (formed when lava or magma cools), sedimentary (formed from layers pressed together), and metamorphic — and that fossils are found in sedimentary rock

Sign in to track this

What mastery looks like

  • Name the three main rock types: igneous, sedimentary, metamorphic
  • Explain that igneous rock forms when lava or magma cools and hardens
  • State that fossils are preserved in sedimentary rock because it forms in layers

Check your understanding

If Types of Rock finds different rocks on a beach walk, can they sort them and explain that some formed from cooled lava, some from layers pressed together over time, and that fossils are found in the layered ones?
