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 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 it unlikely that fossils would be found in igneous rock?
Igneous rock is cooled Magma. Organic material is vaporized at that heat. Fossils are readily fornd in sedimentary rock where the organic material is covered under layers of silt which, through time and pressure, forms into sedimentary rock.

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 is a palynomorph?
A palynomorph is an organic microfossil found in sedimentary deposits and composed of organic material.
What are sedimentary rocks from living or once-living material called?
They are called organic sedimentary rock.
What are pieces of rock and organic material pressed together?
sedimentary rock
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.
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.
What coal is sedimentary rock?
All coal is metamorphic and sedimentary rock. When coal forms it is made out of ancient organic material, and over a long period of time the coal is buried under sediments and water. (That part makes it sedimentary) Over time in order to make the coal we know today heat and pressure (That is what makes it metamorphic) makes the organic material turn hard and solid to become coal.
Why are coal and rock limestone classified as organic sedimentary rocks?
The material comprising the rocks coal and limestone are derived from organisms. Therefore, they are classified as organic sedimentary rocks.
Sedimentary rock that is formed from material that was once alive?
It is called an organic rock.
Sedimentary rocks that form from living or once-living material are called?
Organic
Does oil form in sedimentary rocks?
Yes. Oil forms in sedimentary rock from organic material that settle with the original sediment.
