What states that older rocks lie below younger rocks in undisturbed sequences?
law of superposition
Geology. a basic law of geochronology, stating that in any undisturbed sequence of rocks deposited in layers, the youngest layer is on top and the oldest on bottom, each layer being younger than the one beneath it and older than the one above it.
Are older rocks always located below younger rocks?
a principle that states younger rocks lie above older rocks in undisturbed sequences. Younger over older. When sedimentary rock layers are being deposited, gravity forces them to be deposited as flat, horizontal layers. A metamorphic rock is always older than the non-metamorphosed rocks around it.
What are the rock layers from oldest to youngest?
The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first) and rock strata (layers) closest to the ground surface are the youngest (formed most recently).
Which of the following states that the oldest rocks are at the bottom of undisturbed rock layers?
The principle of superposition
The principle of superposition states that in an undisturbed rock sequence, the oldest rocks are at the bottom and each successive layer is younger than the layer beneath.
What do you think is below the oldest layer?
The youngest rock layers are at the top and the oldest are at the bottom, which is described by the law of superposition.
Which dating method states that younger rocks are found on top of older rocks in the fossil record?
principle of superposition
Younger layers are deposited on top of older layers (principle of superposition).
Where are the youngest rocks on Earth found?
the mid-ocean ridges
Scientists found that the youngest rocks are located at the mid-ocean ridges and the older rock is found far from mid-ocean ridges. This finding provided support for the Theory of Plate Tectonics.
Where is the oldest rock?
Bedrock along the northeast coast of Hudson Bay, Canada, has the oldest rock on Earth. Canadian bedrock more than 4 billion years old may be the oldest known section of the Earth’s early crust.
