What geography law says that the oldest rocks are on the bottom?

The law that states the oldest rocks are found at the bottom of rock layers is known as the Law of Superposition. This principle, fundamental to geology and stratigraphy, asserts that in any undisturbed sequence of sedimentary rocks, the layers are deposited in chronological order, with the oldest layers at the bottom and progressively younger layers on top. This law helps geologists determine the relative ages of rock formations and the fossils contained within them.


Is the layer of rock at the bottom of a sedimentatry rock younger or older?

The layer of rock at the bottom of a sedimentary rock is older. This is due to the principle of superposition, which states that in an undisturbed sequence of rock layers, the oldest rocks are at the bottom and the youngest are at the top.


What is the younger rocks on top called?

The concept you are referring to is called the principle of superposition in geology. It states that in an undisturbed sequence of rock layers, the youngest rocks are at the top and the oldest are at the bottom.


What law suggests that older rock strata are at the bottom and younger rock strata are at the top?

The law that suggests that older rock strata are at the bottom and younger rock strata are at the top is the law of superposition. This principle states that in an undisturbed sequence of sedimentary rocks, the oldest rocks will be at the bottom and the youngest at the top due to the natural layering process over time.


What is based on the idea that younger rock layers are deposited on top of older rock layers in undisturbed areas?

The principle of superposition states that in undisturbed sedimentary rock layers, the youngest layers will be on top and the oldest layers will be at the bottom. This principle forms the basis of relative dating in geology.

The rock at the bottom of an undisturbed sequence is?

The bottom is oldest. The top is newest. -From bottom to top is the equivalent of oldest to youngest in an undisturbed sequence.

Could you tell me something about realative ages of rocks for a project please?

When you look at a rock that has undisturbed layers, the bottom layers are older and the upper layers are younger. Anytime a rock layer crosses another (ie. an intrusion), the crossing layer is younger.

What does the principle of superposition state?

Layers at the bottom are the oldest.


Younger layers of undisturbed sedimentary rock are above older layers according to?

the principle of superposition, which states that in an undisturbed sequence of rock layers, the youngest layer is on top and the oldest is on the bottom. This principle helps geologists determine the relative ages of rock layers based on their position in a stratigraphic sequence.
