Edit610 Rock Cycle

  1. 1. The Rock Cycle Magma Barbara King EDIT610 Click on the gray arrow to continue
  2. 2. • Students will observe and compare several different kinds of rocks. • Students will observe fossil remains and compare to pictures of original. • Students will observe via pictures the effects of weathering, erosion, temperature and pressure.
  3. 3. Click here to learn the definition of Igneous Rocks
  4. 4. Scoria rocks are Igneous rocks which were formed when lava cooled quickly above ground. You can see where little pockets of air had been.
  5. 5. Basalt is an extrusive igneous rock that is very dark in color. It is the most common type of rock in the Earth’s crust, and makes up most of the ocean floor.
  6. 6. Basalt is also an abundant rock on the Moon. Olympus Mons is a shield volcano on Mars. It was formed from basaltic lava flows. It Is the highest mountain on Mars and is the largest known volcano in our solar system.
  7. 7. Pillow basalts on the South Pacific seafloor.
  8. 8. Tuff is rock that is composed of volcanic ash and other materials that were ejected from a Volcano, fell to Earth, and then cooled to form rocks. .
  9. 9. Pumice rocks are Igneous rocks which were formed when lava cooled quickly above ground. You can see where little pockets of air had been. This rock is so light, that many pumice rocks will actually float in water. Because this rock is so light, it s often used for decorative landscape stone. Ground to a powder, it is often used as an abrasive in soaps.
  10. 10. Are these examples of Igneous Rocks? Obsidian Granite No Yes Yes No
  11. 11. You are correct! This is an example of an Igneous Rock! Click on the Sedimentary Rock to continue.
  12. 12. You are incorrect! Click on the rock below to go back and review Igneous Rocks
  13. 13. Parts of rocks, materials, or animal or plant material combined to form rock. Click here to learn the definition of Sedimentary Rocks
  14. 14. Shale rock is a type of sedimentary rock formed from clay. They are used to make bricks and other materials that are fired in a kiln.
  15. 15. Sandstone rocks are sedimentary rocks made from small grains of sand and matrix. They are often used as building stones.
  16. 16. Limestone rocks are sedimentary rocks that are made from the mineral calcite which came from the beds of evaporated seas and lakes and from sea animal shells. This rock is used in concrete and is an excellent building stone .
  17. 17. Conglomerate rocks are sedimentary rocks. They are made up of large sediments like sand and pebbles. The sediment is so large that pressure alone cannot hold the rock together, it is also cemented together with dissolved minerals.
  18. 18. Gypsum rocks are sedimentary rocks made up of sulfate mineral and formed as the result of evaporating sea water In massive prehistoric basins. It is very soft and is used to make Plaster of Paris, casts, molds, and wallboards.
  19. 19. Coal is made up of layers of plant and vegetable material that has been compacted, hardened and transformed by heat and pressure over millions of years.
  20. 20. Are these examples of Sedimentary Rocks? No Yes Yes No Coal Sandstone
  21. 21. You are correct! This is an example of a Sedimentary Rock! Click on the Fossil to continue.
  22. 22. You are incorrect! Click on the rock below to go back and review Sedimentary Rocks
  23. 23. What are Fossils? Fossils are the remains or impressions left by plants or animals that lived a long time ago.
  24. 24. Fossil of Trilobite Click on the fossil to see the Trilobite
  25. 25. Fossil of Horn Coral Click on the fossil to see the Horn Coral
  26. 26. Mosasuar Tooth Fossil Click on the Mosasuar tooth fossil to see a Mosasuar
  27. 27. True or False. Fossils tell us about Earth’s future. True False
  28. 28. Try Again! Fossils tell us a story about the Earth’s past! Click on the Metamorphic rock to continue.
  29. 29. Great Job! Fossils don’t tell us about Earth’s future – They tell us about Earth’s past! Click on the Metamorphic Rock to continue.
  30. 30. Rock that was once one form of rock but has changed to another under the influence of heat or pressure. Click here to learn the definition of Metamorphic Rocks
  31. 31. Formed by the metamorphism of limestone.
  32. 32. Formed by the metamorphism of sandstone.
  33. 33. Formed by the metamorphism of shale.
  34. 34. Are these examples of Metamorphic Rocks? No Yes No Marble Yes Slate
  35. 35. You are correct! This is an example of a Metamorphic Rock! Click the rock to continue.
  36. 36. Click on the rock below to go back and review Metamorphic Rocks You are Incorrect!
  37. 37. How do rocks change?
  38. 38. Weathering Weathering is the process that causes rocks to crumble, crack, or break. Click on the picture to reveal the definition of “Weathering”.
  39. 39. Erosion Movement of weathered rock. Click on the picture to reveal the definition of “Erosion”.
  40. 40. Temperature
  41. 41. Pressure
