The principle is called superposition, and applies to bodies of rock which have not been disturbed by the forces of nature which could reposition or overturn them.
Superposition for APEX
superposition
The priciple of 'superposition'. Layers closer to the surface are younger. Age increases with depth.
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.
The oldest layers of undisturbed sediment are at the bottom.
Principle stating that older rock layers are beneath younger rock layers.
Normally, the oldest rocks are found at the bottom of the layers, being the first of the sediments that were deposited.
In an undisturbed strata, the oldest layers are at the bottom. It's called the law or principle of superposition.
The priciple of 'superposition'. Layers closer to the surface are younger. Age increases with depth.
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.
It is called Superposition.
The oldest layers of undisturbed sediment are at the bottom.
principle of superposition
Principle stating that older rock layers are beneath younger rock layers.
Layers at the bottom are the oldest.
The oldest rocks (layers) are at the bottom. The youngestrocks (layers) are at the top
A geologist uses the principle of superposition to determine the relative ages of rocks and sedimentary layers. This principle states that in undisturbed layers of rock, the youngest layers are at the top while the oldest layers are at the bottom. By observing the order in which different rock layers are stacked, a geologist can infer the sequence of events that happened over time in a particular location.
