Presentation Transcript

  1. Different types of rock There are many different types of rocks in the world.

  2. Identifying rocks

  3. Identifying rocks: summary type description examples sedimentary sandstone and limestone the softest rock type, containing layers and sometimes fossils usually harder than sedimentary rocks, containing thin layers and twisted fossils metamorphic marble and slate usually the hardest rock type, containing shiny crystals igneous basalt and granite

  4. Different rocks = different uses

  5. Formation of sedimentary rocks

  6. Formation of metamorphic rocks Sedimentary rocks are turned into metamorphic rocks by the extreme pressures and temperatures deep within the Earth. These conditions change the structure of the rocks so that new layers are formed. more heat heat more pressure pressure Mixture of grains in structure Heat and pressure compress grains Grains form orderly layers

  7. Formation of igneous rock Magma is a type of molten rock found deep underground. Occasionally magma rises up through the Earth’s surface, causing volcanic eruptions. Igneous rocks are formed when the magma cools and solidifies. extrusive igneous rock • When magma cools above the surface, extrusive igneous rocks are formed. intrusive igneous rock • When magma cools below the surface, intrusive igneous rocks are formed. magma

  8. Crystal size in igneous rocks

  9. The rock cycle

  10. The rock cycle: in words

  11. The rock cycle: summary

  12. From weathering to sedimentation
