Organic rock
Organic rock
A sedimentary rock is formed next, through the accumulation of the weathered and disintegrated matter from the igneous rock.
The only sedimentary rock type that can be formed from things that were once alive is organic sedimentary rock. It is primarily composed of the remains of plants and animals, such as shells, bones, and plant matter. These organic materials undergo compaction and cementation over time to form rocks like limestone and coal.
Skeletal remains of many sea creatures settle on the ocean floor. Here they mix with sediments and eventually become sedimentary rock.
Clastic sediments are sediments that have particles or pieces of rock (clasts) in them. The clasts can be of igneous, metamorphic or sedimentary rock. Non-clastic sediments are made up of dissolved minerals or organic matter.
Organic rock
yes it can.
Organic matter was compressed and heated
Bituminous coal is an organic sedimentary rock formed from the partially decayed remains of plants. Anthracite coal is considered metamorphic rock, and is derived from a bituminous coal protolith. Coal.
the meaning of formed is an organized characteristic of living matter
Yes, living matter is formed from atoms.
Sedimentary rock
orgenic matter was compressed and heatedBy: crystal :)
They are classified as clastic or non-clastic. Clastic sedimentary rocks are formed from rock particles of various sizes. Non-clastic rocks are formed from precipitation of minerals out of solution or by the lithification of organic matter.
A sedimentary rock is formed next, through the accumulation of the weathered and disintegrated matter from the igneous rock.
Metamorphic, igneous, and past sedimentary rocks are turned into sediments by weathering and erosion. Then, the sediment are deposited. Finally, by compaction and/or cementation, a sedimentary rock is formed
It varies with the type of rock being formed. Some igneous rock is formed in a matter of minutes; some sedimentary rock is formed in processes requiring many millions of years.
