How is petroleum formed?
scientists think that petroleum formed from the remains of plankton and other microscopic protists, plants, and animals living in shallow seas millions of years ago. The remains of these organisms settled on the ocean floor and were covered by sediments. Over millions of years, the pressure and heat produced by the sediments coverted the remains of these organisms into a syrupy liquid.
Carnivorous birds that fed on organisms exposed to this chemical produced fragile eggs The chemical is?
DDT
Are sediments buried 3 to 4 km deep experience temperature that start the chemical and mineral changes that cause cementation?
NO
What is the chemical link between generations and all living organisms?
DNA is the chemical link between generations and all living organisms. DNA, which stands for deoxyribonucleic acid, is a molecule.
What chemical reactions are often aided by protein catalysts known as enzymes?
These are the chemical reactions occuring in living organisms.
What is the chemical sediments?
Chemical sediments are mineral precipitate :)
What is the difference between siliciclastic and chemical or biochemical sedimentary rocks?
1) Chemical and biological sedimentary rocks are produced by chemical weathering instead of the siliciclastic sediments which are created by physical weathering. Because physical weathering is much more often than the chemical weathering there are 10 times more clastic sediments in the earth's crust than chemical and biological sediments.
Compare and contrast clastic sediments with chemical sediments?
You cant
How do chemical sediments produce rock?
Chemical sediments, when conditions are right, precipitates to form chemical sediments. This precipitation occurs one of two ways, by physical processes, or by biochemical origin.
What are created when the bodies of dead organisms are buried in the sediments or sand and mineralize over time?
Various sedimentary rock is created. Examples include: * Marble * Limestone
What is one product of chemical weathering?
the product of weathering issand clay and rock fragments
Chemical sediments and its example rocks?
what are the chemical sediments example? An example would be salt. As seawater evaporates from a surface, what is left is salt.
Sediments made from microscopic shells that settle to the bottom when the organisms that produced them die are called?
Biogeneous sediments
What is the sedimentation?
Chemical sediments are mineral precipitate :)
How do chemical rocks form?
The key is the sediments. ... Biochemical sedimentary rocks are formed from organic processes that involve living organisms producing the sediments. These living organisms can be snails and clams whose discarded calcium carbonate shells can form limestone.
How are sediments created and how do those sediments make new landforms?
Idek
Is natural gas is formed from dead organisms buried in sediments?
yes
