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.
What else can I help you with?
What is the definition of foliated rocks?
rocks that do not have a layered structure.
What is it called when younger rocks are layered on top of older rocks?
superposition
Are sedimentary rocks usually layered?
Yes
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.
Why are rocks layered?
because god made it so
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 is a layer called?
Two kinds of layered desserts are parfait and trifle.
What do you call the layering in igneous rocks?
"layering" As in "layered" igneous intrusion.
What is the difference between foliate and nonfloliated rocks?
Foliated rocks have a layered or banded structure due to the alignment of minerals, like slate or schist. Non-foliated rocks lack this layered structure and instead have a more uniform composition, like marble or quartzite.
What are other kinds of rocks?
other kinds of rocks are sedimentary rock or igneous rock
What (who)are stromatolites?
The stromatolites are the layered mounds, columns, and the sheet-like sedimentary rocks.
