Sedimentary Rocks Flashcards
How are the grains in Sedimentary Rocks arranged
They are arranged in layers
What are some examples of Sedimentary Rocks
Chalk, limestone and Sandstone
What is the process of making Sedimentary Rocks
Transport - deposition - sedimentation - compaction- cementation
What is the definition of Transportation
Sediment transport is the first all of the processes by which the sediment is formed. For example, small pebbles of rock are rolled along a river-bed.
What is the definition of Deposition
In deposition, sediment which was carried in transport is laid down.
What is the definition of Sedimentation
Layers of sediment form on top of each other in sedimentation.
What is the definition of Compaction
As more and more layers build up, the weight of the layers on top compacts the layers below.
What is the definition of Cementation
The weight of the sediments on top squashes the sediments at the bottom in a process called compaction. This squeezes out the water from between the pieces of rock and crystals of different salts form. The crystals stick the pieces of rock together. This process is called cementation.
What could be found in a Sedimentary Rock
Fossils
Do Sedimentary rocks have crystals
No, Sedimentary rocks do not have crystals
