  3. What are sediments? How do the sediment particles compare to the rock they came from? Sedimentary rocks

  4. Real sedimentary rock is formed as layers of soil, silt, sand, seashells, and remains of dead animals, etc. settle on the sea floor and built up thick layers. The constant layering of the sediments creates a great amount of weight on the layers below. There are many small gaps in between the particles. Minerals from the water seep into the spaces between the particles and help cement the particles into solid rock. An example of this is stalactites and stalagmites. As the pressure increases, water is forced out and the tiny particles compact. The processes of compaction (pressing tightly together) and cementation (binding particles together) complete the process of turning sediments into rock Real sedimentary rocks

  5. Sandstone Limestone Shale Types of sedimentary rocks

  6. What role did the Epsom salt play in making the model? What are some limitations of this model that show the process of forming sedimentary rock? What did the sand represent? The Grand Canyon is made up of sandstone, limestone, and shale. What do these rocks have in common? Sedimentary rock

  10. How do the processes of formation differ between coal, oil, and natural gas? Differences in formations

  11. Microscopic marine or freshwater organisms died and fell to the sea floor. Here they were buried under sediment and other rock. The rock squeezed the diatoms, and the energy in their bodies could not escape. The carbon eventually turned into oil under great pressure and heat. As the Earth changed, it moved and folded. Pockets were formed where oil and natural gas can be found. Natural Gas and oil

  12. Coal is different because it is formed by decayed plant material. Most of our coal was formed about 300 million years ago, when steamy swamps covered much of the earth. As plants and trees died, their remains sank to the bottom of the swampy areas, accumulating layer upon layer and eventually forming a soggy , dense material called peat. Over long periods of time, the makeup of the Earth’s surface changed. Seas and rivers caused deposits of sand, clay, and other mineral matter to accumulate, burying the peat. Sandstone and other sedimentary rocks were formed, and the pressure caused by their weight squeezed water from the peat. Increasingly deeper burial and the heat associated with it gradually changed the material to coal. Coal formation
