Text of The rock cycle

  • 1. The Rock Cycle

2. What is the rock cycle?

  • It is a model that shows how closely related all the different types of rocks are to each other.
    • The amount of rock material on earth remains the same
    • However, the rocks go through many different transformations

3. How does the rock cycle work?

  • Form sedimentary rocks
  • Igneous is known to be the primary (parent) rock on earth.
    • As the rocks come into contact with weathering and erosion , pieces break off
    • These pieces get transported and put together to form sedimentary rocks

4. Form into MetamorphicRocks

  • If these rocks or the igneous rocks are exposed to huge amounts pressure and heat they form into metamorphic rocks

5. Form into Igneous rocks

  • If the metamorphic rocks or the sedimentary rocks melt and form into magma then they create igneous rocks

6. General Rule !!!

  • ANY TYPE OF ROCK CAN FORM INTO ANY OTHER TYPE OF ROCK AS LONG AS IT IS SUNJECT TO THE RIGHT CONDITIONS

7. Proof #1 of the rock Cycle

  • When we look at a sedimentary rock carefully
    • We see particles of all types of rock and from all over the place

8. Proof of the Rock Cycle

  • When we look at other types of rocks we can see that the rocks have gone through many different changes.

9. How are the rocks used?

  • Igneous
    • Granite for example is used to build monuments etc
    • Might be crushed and used for roads etc

10.

  • Sedimentary
    • Especially sandstone is commonly used in construction and building houses and buildings

11.

  • Foliated metamorphic rocks
    • Can be cut and used for roofing
  • Non-foliated (like marble0 is great for making statues etc

12. Resource Conservation 13. Introduction

  • The Earths population is growing by the second
    • Therefore the demand for energy and products has rapidly increased
    • What is the problem and solution ?

14. Fossil Fuels

  • Right now fossil fuels is the primary source of our energy
    • Fossil fuels include
      • Coal
      • Oil
      • Natural gas
    • They are non-renewable sources because we use too much too quickly

15. What can we do?

  • We can use alternative energy
    • Solar
    • Hydropower (water powered)
    • Wind
    • Wave
    • Nuclear energy
    • These do less harm to the environment than fossil fuels

16. The 4 Rs

  • Reduce
    • We can reduce how much fule we use
  • Reuse
    • We what we used already
  • Recycle
    • Use materials that can be recycled into new
      • Paper into recyclable paper
  • Reclaim
    • We can collect and use what has already been thrown out
