Some examples of sedimentary rocks formed by chemical precipitation from seawater are limestone, dolomite, and evaporites such as rock salt and gypsum. These rocks form when minerals in seawater precipitate out and accumulate over time to create solid rock formations.

Chemical rock formed by crystallization of excess dissolved minerals?
The chemical rock primarily formed through precipitation from mineral-rich water that has partially evaporated, leaving behind excess dissolved minerals that can crystallize. Examples include limestone formed from the precipitation of calcite, and rock salt formed from the crystallization of halite.
Which process most likely formed a layer of the sedimentary rock gypsum?
precipitation from seawater
How are most carbonate rocks formed?
Most carbonate rocks, such as limestone and dolomite, are formed through the accumulation and cementation of calcareous marine organisms like corals, mollusks, and algae. These organisms produce calcium carbonate shells and skeletons that build up over time to create carbonate rock formations. Other processes, like precipitation from seawater or chemical reactions in caves, can also contribute to the formation of carbonate rocks.
Why is salt classified as a mineral?
Salt is classified as a mineral because it is a naturally occurring inorganic solid with a definite chemical composition and orderly atomic structure. It is formed through geological processes such as evaporation of seawater or the precipitation of minerals from underground brine deposits. Salt meets the criteria to be considered a mineral based on its physical and chemical properties.
List three major groups of sedimentary rock?
Clastic sedimentary rocks: Formed from the accumulation of mineral and rock fragments that are cemented together. Chemical sedimentary rocks: Formed from precipitation of minerals dissolved in water. Organic sedimentary rocks: Formed from the accumulation of organic material, such as plants or animals.
Which rock could be formed either by deposition of animal shells and skeletons or by precipitation from evaporating seawater?
Limestone is a rock that can be formed through the accumulation of animal shells and skeletons, called biogenic limestone, or through the precipitation of calcium carbonate from evaporating seawater, known as chemical limestone.
What is formed from evaporation or precipitation of seawater?
When sea water evaporates it leaves the salt behind and takes the water into orbit
What is a type of sedimentary rock formed by the precipitation of minerals dissolved in a lake river or seawater?
sedimentary rock formed by the denudational process of various activity. the sediments in sea water may deposited and thus lead to the formation of sedimentary rock
what are chemical rocks formed by?
By precipitation or evaporation of saturated solutions.
What is formed from the chemical precipitation of minerals from water?
Salt beds.
What is solute from solution?
During a chemical reaction, a precipitate is sometimes formed in the solution. The precipitation is the solid that is formed within a solution.
What is rock salt made from the evaporation of seawater?
Rock salt is primarily composed of sodium chloride and is formed by the evaporation of seawater. As the seawater evaporates, the salt crystallizes and forms deposits that are then harvested for various industrial and culinary purposes.
Which process most likely formed a layer of the sedimentary rock gypsum?
precipitation from seawater
What rock is formed from biological remains or precipitation?
From biological processes: organic sedimentary rock.From precipitation or evaporation: chemical sedimentary rock.
Chemical rock formed by crystallization of excess dissolved minerals?
The chemical rock primarily formed through precipitation from mineral-rich water that has partially evaporated, leaving behind excess dissolved minerals that can crystallize. Examples include limestone formed from the precipitation of calcite, and rock salt formed from the crystallization of halite.
Main tips of sedimentray rocks are?
Clastic--formed from eroded rock particles Chemical--formed from the precipitation of chemically saturated solutions.
Is a geode a rock?
A geode is a chemical sedimentary structure formed by mineral precipitation, similar to the way sedimentary cave structures are formed.
