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.
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.
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
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.
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.
Sedimentary rocks
by an chemical
Clastic and chemical rocks are both types of sedimentary rocks. They form from the accumulation and cementation of sediment particles. Clastic rocks are composed of fragments of pre-existing rocks, while chemical rocks form from the precipitation of minerals from water solutions.
No, sedimentary rocks formed from fragments of other rocks are called clastic sedimentary rocks. Chemical sedimentary rocks form from minerals that are dissolved in water and precipitate out to form rocks like limestone or halite.
There are two processes in which sedimentary rocks form. One is chemical, and the other is by deposition (sediment being deposited and then cemented together). Examples of chemical sedimentary rocks are limestone, dolomite, and rock salt.
The three categories of sedimentary rocks are clastic, chemical, and organic. Clastic rocks form from the accumulation of weathered rock fragments, chemical rocks form from the precipitation of minerals from water, and organic rocks form from the remains of living organisms.

the main things that cause metamorphic rocks to form is heat, pressure and chemical fluids.
Chemical sedimentary rocks form from solutions (water with something in it).
the main things that cause metamorphic rocks to form is heat, pressure and chemical fluids.
The main sub-categories of sedimentary rocks are clastic, chemical, and organic. Clastic sedimentary rocks form from the accumulation and cementation of fragments of pre-existing rocks. Chemical sedimentary rocks form from the precipitation of minerals from water solutions. Organic sedimentary rocks form from the accumulation and compression of organic materials, such as plant or animal remains.
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.
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.
