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.
Fossil fuel forms from the dead organisms acted on by temperature and pressure of the earth over millions of years.
It would form a Sedimentary Rock from heat and pressure after a millions of years.
Carbon under pressure for millions of years will make diamonds.
They are called Biologic sedimentary rocks. Formed when large number of living thing die.
If put under tremendous pressure for millions of years - which is what happened to slate and sandstone.
Coal takes millions of years to form from the pressure of dead plants and trees in swamps.
Fossil fuel forms from the dead organisms acted on by temperature and pressure of the earth over millions of years.

Coal, Gas and Oil. They are so-called because all three are the fossilised remains of plants and sea creatures. When these died, their remains sank to the bottom of oceans. Eventually sedimentary rock formed and the material was altered by heat and pressure inside the earth over millions of years
Extreme heat and pressure over millions of years.
Millions of years under constant pressure and heat.
Its caused by dinosaurs decomposeing and millions of years if heat and pressure
diamonds
Carbon under pressure for millions of years will make diamonds.
The Colorado river is at the bottom of the grand canyon.Over millions of years,it has carved the biggest gorge in the world.
