Sedimentary Rock Notesheets
- Sedimentary Rocks
- Sedimentary rocks form from various types of ______.
- Sedimentary rocks make up ______of ______rocks and only about ______of Earth’s crust.
- Which rock is it that makes up continental crust? ______
- Which rock is it that makes up oceanic crust? ______
- Both of those are ______rocks.
- Three Kinds of Sedimentary Rocks
- Clastic –
For example: Shale, sandstone, conglomerate
- Crystalline –
For example: Rock salt and chemical limestone
- Bioclastic –
For example: Coal and limestone from shells (coquina)
- 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.
- 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?
- Bioclastic (organic) Sedimentary Rocks
- Also called ______sedimentary rocks.
- Formed from ______- ______things like plants and animals.
- For example: Plants ______and ______and form ______.
- Another example: ______can get broken up ______back together to form ______( )
