Want this question answered?
Rock layers are formed by sedimentation. Existing rocks weather and erode, are deposited, covered with additional sediments, compacted and cemented together by the precipitation of minerals from the fluids between the particles. There are other instances where layers can be created, such as repeated volcanic eruptions, but the bulk of rock layers are sedimentary in origin.
Firstly the rocks are weathered and eroded from an area above ground. Then, they are usually transported down to the sea via rivers. Once they are deposited in the sea, a lot of different layers pile up on top of each other on the sea bed. The Layers are then buried deeper and compacted, to form a sedimentary rock. Hope this helped :)
Fossil remains
The answer is: Relative dating
A sedimentary rock is little pieces of other things (other rocks, dead material, or stuff settling out of water) bound together (generally by silica, carbonate, iron oxide, or something else acting like a glue).
hahahahah
...sedimentary rock is formed. OR ...strata is formed. Try either.

Sedimentary rocks are made by the majority of the crust are covered by a thin veneer of loose sediment, and the rock which is made as layers of this debris get compacted and cemented together.
when the bits of the rocks get deposited it forms layers after many years these layers of sediment gets cementated which means gets squashed and compacted which means gets glued and they forms in to sedimentary rocks.thanks for reading
can you ask how many layers deposited within biocorrelation
a lot of sand compacted into layers
The layers of soil that were naturally deposited are called, 'Horizons'.
