What is the Arrangement of rock layers based on their ages?
A geologic column is an arrangement of rock layers in which the oldest rocks are at the bottom. The upper part of the column is rich in fossils.
What does the principle of superposition tell you about the relative ages of sedimentary rock layers?
Younger layers are deposited on top of older layers, whether the layer is sedimentary or volcanic. Occasionally faults may result in overthrusts, where a series of older layers may be pushed over the top of younger layers. But this is rare. In general, the older layers will be the lower layers.
What layer of rock would you most likely find a fossil?
Is at the bottom of course! Since sedimentary rock is formed when layers build up and then harden. So the younger would be at the top.!
What can you learn from exposed layers of rock?
You learn that expose rock layers are the evidence that there was erosion and disturbances going on in that area.
What can disturb rock layers?
the four rock layer disturbances are: tilting, intrusion, faults, and folding
What are four examples of rock disturbances?

Are Aquifers rock layers?
Aquifers are permeable layers of rock that have non permeable layers of rock under them so water remains in the permeable layers
How do geologist know that rock layers are undisturbed?

Gaps in rock layers that develop when agents of erosion remove existing rock layers?
Gaps in rock layers that develop when agents of erosion remove existing rock layers are known as unconformities.
What is the sinking of rock layers?
the sinking of the rock layers is called subsidence
What does it mean for rock layers that are forming?
Rock layers that are forming are stratifying.
What do you call the layers in sedimentary rock?
Sedimentary rock layers. your welcome
How do we know if rock layers are undisturbed?
