Sedimentary Rock Notesheets

  1. Sedimentary Rocks
  2. Sedimentary rocks form from various types of ______.
  3. Sedimentary rocks make up ______of ______rocks and only about ______of Earth’s crust.
  4. Which rock is it that makes up continental crust? ______
  5. Which rock is it that makes up oceanic crust? ______
  6. Both of those are ______rocks.
  1. Three Kinds of Sedimentary Rocks
  2. Clastic –

For example: Shale, sandstone, conglomerate

  1. Crystalline –

For example: Rock salt and chemical limestone

  1. Bioclastic –

For example: Coal and limestone from shells (coquina)

  1. Clastic Sedimentary Rocks
  • Sediment is ______and then goes through the process of ______(forming sediment into a sedimentary rock).
  • Clastic sedimentary rocks are characterized based on their ______.
  • Grain sizes vary from ______(pebbles, cobbles, boulders), to ______( sand ), to ______(silt and clay).
  • How Does the Sediment Get Sorted Into Different Sizes?
  • ______(rivers, streams, creeks) pick up sediment and carry it along its travels.
  • The ______the water is moving, the ______the particle that can be carried, and vice-versa.

When a river hits a larger body of water, like an ocean or a lake, it’s like hitting a ______. This results in the river “______” – dropping all the sediment it’s been carring.

  • The sediment gets dumped according to ______!!
  • The ______sediment gets deposited ______, since it’s bigger, heavier, and sinks first.
  • Then, the sediment gradually gets ______the ______you get from where the river hit the ocean or lake.
  • Therefore, ______get made where the larger sediment got deposited and the ______get made further away from that point.
  1. Crystalline (Chemical) Sedimentary Rocks
  • Also called ______sedimentary rocks.
  • Chemical action or ______causes minerals to drop out of ______.
  • This process creates crystalline or chemical sedimentary rocks.
  • For example: ______will ______out of water and build-up to form ______(it will fizz with acid since it has calcite in it!)
  • What happens when salty water evaporates and just salt is left behind?
  1. Bioclastic (organic) Sedimentary Rocks
  2. Also called ______sedimentary rocks.
  3. Formed from ______- ______things like plants and animals.
  4. For example: Plants ______and ______and form ______.
  5. Another example: ______can get broken up ______back together to form ______( )
