They're called strata. Strata less than 1cm thick are Laminae.
sedementary rocks are used for (since they have grains and layers) they are good for pavements...i think, well i have to have 2 go now

because organism live only in sedementary rocks
No, in fact plenty of fossils are found in sedementary rocks.
The layers found in sedimentary rocks are called strata. These are horizontal layers of sediment that have been deposited over time and then compacted and cemented together to form rock. Each layer represents a different time period in Earth's history.
sandstones, shale
These thin layers are called sedimentary rocks, which are formed from the accumulation and compression of sediments over time. Sedimentary rocks are one of the three main types of rocks found on Earth's surface, along with igneous and metamorphic rocks.
Sedimentary rocks are the type of rocks that are mostly arranged in layers. The way in which the layers are arranged is commonly called bedding.
In rock layers, the oldest rocks are typically found at the bottom. This is due to the principle of superposition, which states that in an undisturbed sequence of sedimentary rocks, the oldest rocks are deposited first and are at the bottom, while the youngest rocks are at the top.
Trilobites are ancient fossils commonly found in dome-shaped rocks composed of thin layers of sediment. These creatures have a hard exoskeleton that can be well-preserved in sedimentary rocks.
