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 chemical and organic rocks classified?
Both organic sedimentary (like coal) and chemical sedimentary (like rock salt) rocks are not composed of particles of other rocks. They are different because organic rocks are composed of the remains of living things but chemical rocks are formed by inorganic processes such as evaporation.
What are some differences of physical weathering and chemical weathering?
Physical weathering is due to: rocks hitting other rocks causing them to break up from the action of frost and ice the action of wind or waves or running water the action of plants. Chemical weathering changes the composition of the rock and is due to: water dissolving minerals in the rock oxidation of metals in the rock
What involves ways that rocks break down without changes to what?
Weathering involves ways that rocks break down without changes to their chemical state. Weathering involves mechanical forces e.g. wind and rainfall rather than chemical energy in disintegration or rocks.
What is the chemical makeup of a rock?
The rocks you see around you - the mountains, canyons & riverbeds, are all made of minerals. A rock is made up of 2 or more minerals. Think of a chocolate chip cookie as a rock. The cookie is made of flour, butter, sugar & chocolate. The cookie is like a rock and the flour, butter, sugar & chocolate are like minerals. You need minerals to make rocks, but you don't need rocks to make minerals. All rocks are made of minerals.
Fossils are found only in .?

How does ingenous rocks form?

Do sedimentary rocks form in chemical processes?
Yes, sedimentary rocks can form through chemical processes. One example is the precipitation of minerals from solution, which occurs when dissolved ions in water bond together to form solid minerals. Another example is chemical weathering, where minerals in rocks are dissolved or altered by chemical reactions, leading to the formation of new minerals.
What are two ways that chemical rocks form?
crystalized and minerals
What are the main things that cause rocks to form?
the main things that cause metamorphic rocks to form is heat, pressure and chemical fluids.
How do biochemical sedimentary rocks form?
Chemical sedimentary rocks form from solutions (water with something in it).
What are the main things that cause metamorphic rocks to form?
the main things that cause metamorphic rocks to form is heat, pressure and chemical fluids.
Exaples of chemical weathering?
what types of rocks form when magma cools
How do you classify sedimentary rocks?
The basic division of sedimentary rocks is into clastic and chemical rocks. Clastic rocks are formed when grains form a sediment and are then cemented together, as happens with sandstone or shale. Chemical rocks form when solid precipitates out of solution, for instance when calcium carbonate is formed from sea water to give chalk.

When acids are added to rocks containing a carbonate bubbles form is this evidence of a physical change or chemical change?

What is the or-gin of sedimentary rocks?
weathering of preexisting rocks form clastic sedimentary rocks, Oversaturated water basins form chemical sedimentary rocks after the water evaporates and dead sea organisms settle at the bottom forming biochemical sedimentary rocks.
Is made out of gas or rocks?
Mercury Hg is Element, inliquid natural form, and in different chemical forms, it does come from minerals deposited in liquid or solid form in rocks.....
