Which is the youngest in a sereis of undisturbed rock layers where shale lies between sandstone below and limestone above?
Limestone is the youngest since it's at the top
Is the youngest or oldest rock on top?
youngest
Which layer of rock is the oldest?
The basement is a term sometimes used, and Cratonis another used in a continental context.The Principle of Superposition has it that in a given formation, the top layers are the youngest, and the deeper layers the oldest.
What is the name of a fold in which the youngest rock layers are in center?
Such a fold is called a syncline.
What is a fold in which the youngest rock layers are in the center of the fold called?
Synclines
What rock layer is the youngest?
The principle of superposition states that in an undisturbed sequence of rock layers, the youngest will be at the top, the oldest at the bottom.
What does the law of superposition tell us about rock layers?
youngest on top
Is the top layer of rock the youngest layer?
According to the Law of Superposition, in a depositional sequence of undisturbed rock layers, the top layer of rock is the most recent to form from the processes of lithification or eruption of lava onto the surface, and are therefore the youngest rock layers.
When might the youngest layer in a set of sedimentary rock not be on top?
1. If a set of rock layers has been disturbed by movement of tectonic plates, the youngest layer may no longer be on top.
Explain that folding faulting and uplifting can rearrange the rock layers so the youngest is not always found on top?
Whenfolding, faulting, and uplifting occurs, the youngest rock layer can not always be on top. With folding the oldest rock layer could get folded over on top of a younger layer. When faulting occurs a younger rock layer can become "lower" or pushed more down in the rock layers that was originally shown. When these things happen, then rock layers can become out of order and the youngest layer is not always on the top of the layer.
Which is the youngest in a sereis of undisturbed rock layers where shale lies between sandstone below and limestone above?
Limestone is the youngest since it's at the top
What are the rock layers of balanced rock in Arches National Park?
Erosion removed the youngest layers of rock, but all the rock is sandstone.
What can you tell from undisturbed rock layers?
You can tell the age of the layers. The bottom layer is the oldest and the top is the youngest. When the layers are disturbed they tend to get bent and messed up and you cannot tell the age
Is the youngest or oldest rock on top?
youngest
How are the layers of rock if they are undisturbed?
The undisturbed rock layers are horizontal and in order of age from youngest nearest the surface to oldest at the bottom of the rock unit.
What layer is the youngest layer in the sedimentary rock?
The one closest to the surface because rock layers are laid down one on top of another.
How do you determine the sequence of events in rock layers?
By the law of superposition: Oldest at the bottom and youngest at the top.
