When a rock forms by precipitation and aggregation of minerals from a solution, it is classified as a ________ sedimentary rock.?
Chemical sedimentary rocks form by precipitation of minerals from water. Precipitation is when dissolved materials come out of water. For example: Take a glass of water and pour some salt (halite) into it. The salt will dissolve into the water.

What sedimentary rock is not classified by the size of clastic sediment that forms the rock?
Chemical sedimentary rocks, such as limestone and chert, are not classified by the size of clastic sediment that forms them, as they are formed from dissolved minerals that precipitate out of water. These rocks are made up of minerals that have been dissolved in water and then later crystallize out of solution.
What is the type of sedimentary rock that forms by precipitation of minerals out of water?
Halite and Gypsum, they are called Evaporites and are both rocks and minerals
How do geologist classify sedimentary rocks?
They are classified as clastic or non-clastic. Clastic sedimentary rocks are formed from rock particles of various sizes. Non-clastic rocks are formed from precipitation of minerals out of solution or by the lithification of organic matter.
Three most common natural cements that hold sedimentary rocks together?
Calcite: Formed from calcium carbonate precipitation, calcite cement is a common cement in sedimentary rocks like limestone. Silica: Silica cement is composed of quartz grains and acts as a binding agent in sandstone and other sedimentary rocks. Clay minerals: Clay minerals like illite and kaolinite can act as cementing agents in sedimentary rocks, holding grains together through mineral precipitation.
Is aluminum igneous sedimentary or metamorphic?
Aluminum is not classified as igneous, sedimentary, or metamorphic. It is a metallic element and is naturally found in the Earth's crust, often in combination with other elements or minerals.
Chemocal sedimentary rocks are made from?
Chemical sedimentary rocks are formed by the precipitation of minerals from water.

What rock forms when mineral-rich water evaporates?
Chemical sedimentary rocks are formed from the precipitation from, or evaporation of, water that is saturated with dissolved minerals. In addition, most clastic sedimentary rocks are also formed from the cementing together of sediment particles by the precipitation of minerals from water.
How are sedimentary rocks classified?
Sedimentary rocks are classified based on their mineral composition, grain size, texture, and the way they were formed. The three main types of sedimentary rocks are clastic, chemical, and organic. Clastic rocks are made up of broken fragments of other rocks, chemical rocks form from precipitation of minerals from water, and organic rocks are formed from the accumulation of plant and animal remains.
What is the type of sedimentary rock that forms by precipitation of minerals out of water?
Halite and Gypsum, they are called Evaporites and are both rocks and minerals
Are sedimentary rocks classified tofoliated sedimentary rocks?
No, sedimentary rocks are not classified as foliated. Foliation is a textural feature found in certain types of metamorphic rocks where minerals are aligned in layers or bands due to pressure and heat. Sedimentary rocks are formed by the accumulation and cementation of sediments and do not exhibit foliation.
How are rocks related to minerals What is the difference in how rocks and minerals are classified?
A rock is an agglomeration of different minerals. Minerals are classified into categories based on their chemistry: oxides, sulphides, silicates, carbonates etc. Rocks are classified primarily by the process that formed them: igneous, sedimentary, or metamorphic.

What are two processes that chemical sedimentary rocks are deposited?
Chemical sedimentary rocks can form through processes such as precipitation, where dissolved minerals in water solidify and accumulate to create rock layers. Another process is evaporation, where water evaporates leaving behind concentrated minerals that eventually form into rock.
Is the sedimentary rock a type of mineral?
All rocks are composed of combinations of minerals by definition. Sedimentary rocks can be composed of many different minerals and therefore cannot be classified as a specific mineral. Rocks are the source of most minerals for human use, but they must be separated from the other minerals in the rock.
What sedimentary rocks are formed by chemical precipitation from seawater?
Sedimentary rocks formed by chemical precipitation from seawater include limestone, specifically in the form of travertine and oolitic limestone, as well as evaporites like halite and gypsum. These rocks result from the evaporation of seawater, which leads to the concentration and precipitation of minerals. As seawater evaporates, dissolved minerals crystallize out, forming solid deposits that can accumulate over time.
