The simple answer is that the old rock is at the bottom and the young rock is at the top. But sometimes the Earth has folded its skin over so it's all sideways or even upside down. You can see seashells at 5,000 metres up the Himalayas.
The newest rocks are those formed where the crust is spreading, or as lava flows from volcanoes. This rock was liquified and mixed in its magma form. The oldest rocks are near the centers of continents, mainly underground but occasionally exposed by upthrust folding and/or erosion.

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.
A scientist compares the layers of sedimentary rock in a hillside and then applies the principles of relative dating What can the scientist conclude about the hillside?
The chronological order of rock layers from oldest to youngest
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
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.
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.
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.
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 is the definition for principal of superposition?
states that the lowest rock in layers is the oldest and the highest is the youngest rock layer
Can someone help me Identify the rock layers from oldest to youngest, Thanks!?
This is the problem,Thanks!

The chronological order of rock layers from oldest to youngest
Which of the following correctly lists the layers in order from oldest to youngest?
The oldest is on bottom and youngest on 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 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

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.
