What does clay like material that fell to a lake bottom turn into after a millions of years of pressure and heat?
Over millions of years, clay-like material that falls to a lake bottom is subject to intense pressure and heat. This results in an incredibly slow and gradual process of change. The clay-like material will transform into a sedimentary rock, such as shale or mudstone. These rocks are composed of particles of clay and other minerals that have been cemented together as a result of the pressure and heat. The sedimentary rock will also contain fossils and other evidence of the organisms that were present at the time the clay-like material was deposited. This is because the process of sedimentary rock formation preserves and encases the fossils and other organic material that was present in the clay-like material when it was deposited. Thus, after millions of years of pressure and heat, the clay-like material that fell to a lake bottom is transformed into a sedimentary rock containing fossils and other evidence of past life.
What type of sedimentary rock is coal?
Coal is a type of sedimentary rock known as a combustible sedimentary rock. It is formed from the remains of plants that have been compacted and altered over millions of years under heat and pressure.
What are pieces of rock and organic material pressed together?
sedimentary rock
Are sedimentary rocks formed when sediments are compacted by extreme pressure?
Clastic and organic sedimentary rocks like conglomerate, coal, some limestones, and shale, are formed under pressure from overlying sediments.
Sedimentary rocks that form from living or once-living material are called?
Organic
Why is coal an organic sedimentary rock?
Coal is an organic sedimentary rock because it forms from the remains for plant material. Source : California Edition, Earth Science ; Geology, the enviorment and the Universe Pg. 131

How are organic sedimentary rocks made out of?
This type of sedimentary rock must have organic material to be created. They are called organic because they are made from organic material such as grass or plankton that, over long periods of time, becomes a type of sedimentary rock. This organic material can be the organism itself or may be given off from the organism.
What type of sedimentary rock is coal?
Coal is a type of sedimentary rock known as a combustible sedimentary rock. It is formed from the remains of plants that have been compacted and altered over millions of years under heat and pressure.
Is coal organic or inorganic?
Coal is considered to be organic because it is formed from the remains of plant material that accumulated and underwent a process of heat and pressure over millions of years.
What are sedimentary rocks from living or once-living material called?
Sedimentary rocks formed from living or once-living material are called organic sedimentary rocks. Examples include limestone, coal, and chalk.
What is a palynomorph?
A palynomorph is an organic microfossil found in sedimentary deposits and composed of organic material.
The chemical breakdown of enormous quantities of organic material buried in the sedimentary rocks has produced what type of gas?
The chemical breakdown of enormous quantities of organic material buried in the sedimentary rocks has produced ethane gas.
Why is coal a rock?
Coal is formed from plant material falling on saturated soil (swamps marshes & wetlands), the plant material decomposes only very slowly as no oxygen can reach them, this then gets buried by more organic material. then eventually the organic material is lithified forming coal ( rock formation) .
What are pieces of rock and organic material pressed together?
sedimentary rock
Is coal an organic sedimentary rock?
Most coal is classified as an organic sedimentary rock. The exception would be anthracite, which is metamorphosed bituminous coal.
Is coal clastic organic or chemical?
Coal is an organic sedimentary rock that forms from the accumulation and decomposition of plant material over millions of years. It is primarily composed of carbon, along with varying amounts of other elements like hydrogen, oxygen, and sulfur.
