how do chemical rocks form, are some types of limestone considered a chemical rock, and what mineral does rock salt crystalize from? thank you so much if you choose to answer. im so stumped.

rock salt crystallized from salt water.

Yes, some type of limestone are chemical rocks...gypsum is all around here.

we have to write a 300 word essay on the three types of landforms and i only have 150.

"rock salt" is the common name for the mineral halite.

Chemical rocks form through chemical processes that involve the precipitation or crystallization of minerals from solutions. These solutions can be found in oceans, lakes, or underground water sources. There are various types of chemical rocks, and limestone is indeed considered one of them. Limestone is primarily composed of the mineral calcite (calcium carbonate) and it forms from the accumulation of calcite-rich organic remains or from the precipitation of calcite from water solutions.

Now, let's move on to rock salt. Rock salt is a type of chemical sedimentary rock formed by the crystallization of minerals from saline water bodies such as salt lakes or ancient oceans. The mineral responsible for the formation of rock salt is halite, which is composed of sodium chloride (NaCl). As the water evaporates, the minerals become concentrated and eventually precipitate out as halite crystals, resulting in the formation of rock salt deposits.

To summarize:
1. Chemical rocks form through precipitation or crystallization of minerals from solutions.
2. Limestone is considered a chemical rock and is primarily composed of the mineral calcite (calcium carbonate).
3. Rock salt is a chemical sedimentary rock formed by the crystallization of the mineral halite (sodium chloride) from saline water bodies.
