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.
Which rock unit was most likely formed from chemical precipitates?
Evaporites are rock units that are most likely formed from chemical precipitates. These rocks are formed when minerals precipitate out of solution as water evaporates, leaving behind minerals like halite or gypsum.
Is H2O a precipitate?
No, H2O (water) is not a precipitate. Precipitates are solid substances that form from a chemical reaction in a solution. Water remains in liquid form.
Distinguish between the two categories of chemical sedimentary rock?
One type of chemical sedimentary rock is oolite limestone, which precipitates inorganically. The other type is rocks that are composed of evaporite materials; rocks such as halite, sylvite, gypsum, and barite.
What are the three categories of sedimentary rocks?
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.

What do clastic and chemical rocks have in common?
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.
Is H2O a precipitate?
No, H2O (water) is not a precipitate. Precipitates are solid substances that form from a chemical reaction in a solution. Water remains in liquid form.

What sedimantary rock made of?
Sedimentary rocks are made of various materials such as mineral fragments, organic matter, or chemical precipitates. These materials accumulate over time in layers and become compacted and cemented together to form rocks like sandstone, shale, or limestone.
Are sedimentary rocks formed from fragments of other rocks chemical sedimentary rocks?
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.
What are the three main types of sedimentary rock?
The three main types of sedimentary rocks are clastic, chemical and biochemical. Clastic rocks are made of minerals and rocks including quartz, mica and feldspar. Chemical rocks are created when water precipitates from ground water, lakes or the ocean. Biochemical rocks can be found in the ocean. This sedimentary rock comes from plants or living organisms which helps to build tissue.
Does precipitation indicate that a chemical change has taken place?
In most of the cases it is true but in some cases the reactants may also form the precipitates.
Do sedimentary rocks form in chemical processes?
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.
