Why does sedimentary rock form in horizontal layers?
Sedimentary rocks are types of rock that are formed by the deposit of material at the Earth's surface and within bodies of water. The horizontal layering happens because it has forms with the passing of time over thousands if not millions of years.
Why can only sedimentary rocks contain in tact fossils?
Sedimentary rocks form three horizontal layers: strata, singular and stratum. The organisms that fall into the sedimentary rocks, will then be fossilized in each layer.
Is cross-beds a sedimentary structure?
Cross-beds are horizontal units that are internally comprised of inclined layers. It is a sedimentary structure that forms during deposition on the inclined surfaces of bedforms.
What type of surface bedrock is most commonly found in New York tug hill plateau region?
Horizontal sedimentary rock layers.
One of the key principles of relative dating is the law of superposition which states that?
Younger layers of sedimentary rock are deposited on older layers
Do sedimentary rock layers always stay horizontal?
No. It is not uncommon for the layers to be shifted out of a horizontal position.
What is horizontal bedding?
horizontal bedding is sedimentary rock structure in which layers of rocks lies horizontally.
Sedimentary rocks form distinctive layers at the bottom of a lake?
Rock strata can be formed in layers at the bottom of lakes.
What happens to the very bottom layers of sedimentary rocks over time?
The layers get burried

The surface feature that is produced when horizontal layers of sedimentary rock rise without being folded is a?
plateau
What is the defointion for the law of superstition?
the law of superstition is the geologi principle that states that in horizontal layers of sedimentary rock.Each layer is older than the layer above it and younger than the layer below it
How might graded bedding be used to determine the tops and bottoms of sedimentary rock layers in an area where sedimentary rock is no longer horizontal?
The largest grains will always be deposited first so they will be at the bottom of the beds because they could not form natrually any other way.
Why can only sedimentary rocks contain in tact fossils?
Sedimentary rocks form three horizontal layers: strata, singular and stratum. The organisms that fall into the sedimentary rocks, will then be fossilized in each layer.
In stratified layers of layers of sedimentary what is it called when sediment settles on the bottom and the large grains settle on top?
Reverse Grading.
What are the stratigraphic principles?
The principle of superposition states that in an undisturbed sequence of rock layers, the youngest layer is on top and the oldest layer is at the bottom. The principle of original horizontality states that sedimentary rocks are originally deposited in horizontal layers. The principle of lateral continuity states that rock layers extend continuously in all directions until they thin out or reach a barrier. The principle of cross-cutting relationships states that any geological feature that cuts across a rock layer is younger than the layer it cuts through.
What is law of superpostion?
In geology, the law of superposition states that in any undisturbed sequence of rocks that are deposited in layers, the oldest layers are on the bottom. Each layer is younger than the layer below it.
