Sedimentary rocks are deposited in layers as strata, forming a structure called bedding. The study of sedimentary rocks and rock strata provides information about the subsurface that is useful to scientists to learn about ancient environment of area.
Scientists can use sedimentary rocks to learn about ancient environments by comparing the kind of environment that produces certain kinds of rock today. The type of environment the rocks are produced in today is the same type that would have been needed to produce rocks then.
Sedimentary rocks often contain clues as to the time when they were formed. Sediments can determine what climate the rocks were formd in, what locatio and often contain what is known as INDEX FOSSIL. Index fossils are fossils that lived a relatively short period of time and was widespread. These types of fossils can indicate when certain bedrocks formed.
Sedimentary rocks are laid down from the eroded remains of previous rocks that have been exposed at the Earths surface or from the remains of living creatures. The younger sediments cover the older sediments and thus provide a profile through time telling us:
Thus a geologist learns how to "read" the layers of sediments like the pages of a book, the story told is how the Earth has changed and developed through time - Earth's history.
well, sedimentary rocks contain fossils that are from long ago or bits or particles that are from long ago

by fossils
Sedimentary rocks are broken into two classes: clasticand chemical. Clastic sedimentary rocks are composed of rock particles, and chemical sedimentary rocks are composed of precipitation of minerals in solution.
Both organic sedimentary (like coal) and chemical sedimentary (like rock salt) rocks are not composed of particles of other rocks. They are different because organic rocks are composed of the remains of living things but chemical rocks are formed by inorganic processes such as evaporation.
Sedimentary rocks
volcanic mountains are mostly associated with igneous rocks and sedimentary rocks at their slopes can be found due to weathering,but mountains such as fold mountains can contain igneous rocks,metarmophic ro cks and even sedimentary rocks at their slopes
Gravel, sandstone, and conglomerate are all types of sedimentary rocks.
The vast majority of fossils are found in sedimentary rock.
That depends on the rock. Some sedimentary rocks are used as construction material, or as raw material for different kinds of industries. Older sedimentary rocks have a scientific value as well, as ages of fossils can be determined by studying them.
Sedimentary rocks form from a few different things. Sedimentary rocks form from sediment is deposited out of air, ice, wind and gravity.
it is good
They are called clastic sedimentary rocks.
Sedimentary rocks record; 1. Time (Age) of formation. 2. Environment of formation.
It is true that the composition of a sedimentary rock depends upon the composition of the rocks and living things its sediments come from. Sedimentary rocks form through lithification.
Metamorphic rocks are classified by foliation or lack there of, not sedimentary rocks. They are classified into Clastic Sedimentary, and Chemical Sedimentary.
Biosedimentary rocks (i.e. Biologically formed sedimentary rocks). Eg Coal.
No. The rocks you describe are clastic or detrital sedimentary rocks.

Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
