What to Focus On

  • Lithosphere forms the outer solid crust of Earth
  • Rocks are aggregates of minerals with heterogeneous composition
  • Minerals have definite chemical composition and crystalline structure

  • Formed from solidification of magma or lava
  • Classified as acidic (high silica) or basic (low silica)
  • Intrusive rocks: cooled slowly underground, coarse-grained

  • Formed through denudation processes (weathering and erosion)
  • Deposited in distinct layers or strata
  • Contain fossils that help determine age

Common Mistakes to Avoid

All rocks are formed from magma cooling down

Sedimentary rocks are always soft and igneous rocks are always hard

The rock cycle is a one-way linear process from igneous to sedimentary to metamorphic

Memory Tips

Three main types of rocks: Igneous, Sedimentary, Metamorphic

Igneous rocks form from molten magma

Sedimentary rocks form in layers from eroded materials

Metamorphic rocks change under heat and pressure
