|
This law states that sedimentary rocks are originally deposited into horizontal layers. |
Law of Original Horizontality. |
|
This rock is most often found forming at divergent boundaries. |

|
This term describes how easily a fluid flows. |
Viscosity |
|
This law states that, for rocks that have not been deformed or cross cut, the older rocks are on the bottom and the younger rocks are on the top. |
Law of Superposition |
|
At continent-continent converging boundaries you would expect this type of volcanism. |
Very Little volcanism |
|
This is the name for the process where rocks are broken into smaller fragments. |
Weathering |
|
This type of unconformity is the result of dipping layers being directly overlain by horizon layers. |

|
This type of deformation will typically fracture, break and fault a rock. |
Brittle Deformation |
|
One of these changes will cause a rock to melt. |
Raise temperature, reduce pressure, increase water content |
