Sedimentary rock is layered because the rock is composed of lithified sediments. Sediments are carried wind wind, water, ice, and gravity until they no longer can move due to friction and gravity. Differences seen in individual layers may be because of seasonal changes in depositional materials (springtime flooding), changes in the sediments due to a change in the erosional course of rivers and streams, environmental catastrophes such as flooding and large fires, and a whole host of other influences on the supply of material that make up the individual rock stratum.

What features tell you how a sedimentary rocked is layered?
Sedimentary rocks are often deposited in layers as strata. The feature that tells how a sedimentary rock is layered is called the bedding.
Sedimentary rocks are useful as records of past time because of .?
Their layered structure :)
Is sedimentary rock the only type of layered rock?
No. Extrusive igneous rocks are usually layered. Some metamorphic rocks have foliation, which resembles layering, but it is not the same thing.
What causes pressure for sedimentary rocks?
The pressure is from the weight of rock and sediment layered on top of the rock in question.
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
Are sedimentary rocks usually layered?
Yes
Which minerals or sedimentary rocks are not likely to occur in association with bedded rock salt?
Igneous rocks such as granite or basalt are not likely to occur in association with bedded rock salt, as they form under different conditions. Additionally, metamorphic rocks such as marble or schist are also unlikely to be found in association with bedded rock salt due to their distinct formation processes.

Type of Rock forms in layers?
Sedimentary rocks, and foliated metamorphic rocks form in layers.

What are stromatolities?
The stromatolites are the layered mounds, columns, and the sheet-like sedimentary rocks.
What (who)are stromatolites?

Is sedimentary rock the only type of layered rock?
No. Extrusive igneous rocks are usually layered. Some metamorphic rocks have foliation, which resembles layering, but it is not the same thing.
What types of landforms do you think would have layers?
Those made out of layered sedimentary rocks Those made out of layered igneous rocks Those made out of metamorphic rocks with pronounced planar fabric.
What percentage of rocks on earth are sedimentary?
Approximately 75% of the rocks on Earth are sedimentary. This type of rock forms from the accumulation and compression of sediments over time. Sedimentary rocks are found in a wide range of environments, including oceans, rivers, and deserts.
What kinds of rocks are layered?
At some level, almost all rock is layered. From the first cataclysmic events through periods of glaciation and warm inland seas, layer after layer of rocks have been laid down--one on top of the other. Stratigraphy, the study of layers, is one of basic ways that geologists answer the question "what happened?". There are three kinds of rock: igneous; sedimentary and metamorphic. Of the three, sedimentary rocks are the most obviously layered because they are formed by layers of mud and/or sand.
