What are some of the things about the past which you can learn from studying sedimentary rocks?

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.

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.

∙ 9y agoSedimentary 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:
- What the land being eroded was made from.
- How the sediments were transported and deposited (the geography of the earth at the time of deposition)
- In some cases what the temperature of the environment was
- The environment of the place where they were deposited (lake - desert, river, beach, deep ocean etc)
- In some case the direction of the currents
- In some cases what was living on Earth at the time.
- In some cases records of catastrophic impacts on the Earth or remote volcanic and even cosmological events.
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.

What is the class that includes sedimentary rocks which are deposited from a solution made by organic processes?
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.
How are chemical and organic rocks classified?
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.
Fossils are found only in .?
Sedimentary rocks
What type of rock are mostly found in mountains?
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?
Gravel, sandstone, and conglomerate are all types of sedimentary rocks.
Why do scientists look to sedimentary rocks when studying the history of the Earth?
The vast majority of fossils are found in sedimentary rock.
Is the sedimentary rock strong?
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.
What do sedimentary rocks form from?
Sedimentary rocks form from a few different things. Sedimentary rocks form from sediment is deposited out of air, ice, wind and gravity.
How can sedimentary rocks helpus learn about earths's past?
it is good
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
What two things do sedimentary rocks record?
Sedimentary rocks record; 1. Time (Age) of formation. 2. Environment of formation.
Does the composition of a sedimentary rock depend upon the composition of the rocks and the living things its sediments came from?
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.
Are sedimentary rocks classified tofoliated sedimentary rocks?
Metamorphic rocks are classified by foliation or lack there of, not sedimentary rocks. They are classified into Clastic Sedimentary, and Chemical Sedimentary.
Are sedimentary rocks formed from fragments of other rocks chemical sedimentary rocks?
No. The rocks you describe are clastic or detrital sedimentary rocks.
What types of sedimentary rocks are formed from the remains of dead organisms?
Biosedimentary rocks (i.e. Biologically formed sedimentary rocks). Eg Coal.
What has the author Sam Boggs written?
Sam Boggs has written: 'Petrology of sedimentary rocks' -- subject(s): Sedimentary Rocks 'Petrology of sedimentary rocks' -- subject(s): Rocks, Sedimentary, Sedimentary Rocks
Are there any fossils in sedimentary rocks?
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
