sedimentary rock
Sedimentary rocks are created when layers of debris are compacted and cemented together. These types of rocks are also known as secondary rocks because they often result from fragments of other rocks being cemented together. The type of sedimentary rock you seem to be asking about is organic. Organic sedimentary rock is formed when the sedimentary debris is compiled through organic processes. For example rocks forming as succesive layers of substrate pile onto one another and compact over time.
Sedimentary rocks have flat layers.
metamorphic rocks
Sedimentary Rocks
Rock layers that are forming are stratifying.
a reapedly of layers forming
Sedimentary rock, like limestone, is formed in layers.

Sedimentary Rock is made up of layers of different rocks.
Rock sequencing is a set of rocks that are contained in layers.
Molten Rock from with in earth can force its way up through the layers above it cooling and forming igneous rock.
Layers or strata in sedimentary rock are composed of deposited smaller rock particles and possibly organic matter.
The oldest rocks (layers) are at the bottom. The youngestrocks (layers) are at the top
Water pushes down on the layers of sand and stone. Over time, the water evaporates the leaves the sedimentary rock to dry.
