How do biochemical sedimentary rocks form?
Chemical sedimentary rocks form from solutions (water with something in it).
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.
Which rock type or types can form sedimentary when they are weathered?
Igneous and metamorphic rocks can form sedimentary rocks when they undergo weathering. As these rocks break down into smaller particles through physical and chemical processes, they can be transported and deposited, eventually lithifying into sedimentary rock. Additionally, pre-existing sedimentary rocks can also contribute to the formation of new sedimentary layers through similar weathering and erosion processes.
What type of rocks weather and erode to form sedimentary rocks?
Igneous, metamorphic, and existing sedimentary rocks can weather and erode to form sedimentary rocks. Igneous and metamorphic rocks can break down into sediments through processes like weathering and erosion, which then may accumulate and lithify into sedimentary rocks. Existing sedimentary rocks can also be reworked and lithified to form new sedimentary rocks through processes like compaction and cementation.
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.

What is the first process that occurs in the formation of sedimentary rocks?
Although sedimentary rocks form in a variety of processes, the first process that would occur in the formation of the most common sedimentary rocks would be that of weathering, which is the breakdown of rocks into smaller pieces through chemical or mechanical means by nature.
What All of the following are ways in which sedimentary rocks form EXCEPT A. Lava cooling B. Physical processes C. Chemical processes D. Build up of plant and animal remains?
A. Lava cooling. Sedimentary rocks are formed through the accumulation and cementation of sediments through physical or chemical processes, or by the build-up of plant and animal remains. Lava cooling forms igneous rocks, not sedimentary rocks.

What are the main sub-categories Sedimentary Rock?
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.
What are some examples of chemical sedimentary rock?
Some examples of chemical sedimentary rocks include limestone, dolostone, and rock salt. These rocks form when minerals precipitate out of a solution, such as when water evaporates or through processes like precipitation.
What is more important clastic or chemical sedimentary rocks?
The importance of clastic versus chemical sedimentary rocks largely depends on the context in which they are analyzed. Clastic sedimentary rocks, formed from the accumulation of fragments of other rocks, are crucial for understanding geological processes and sediment transport. In contrast, chemical sedimentary rocks, which form through the precipitation of minerals from solution, are significant for studying past environmental conditions and biogeochemical cycles. Ultimately, both rock types provide valuable insights into Earth's history and processes.
All what are ways in which sedimentary rocks from except?
Sedimentary rocks form through processes such as compaction and cementation of sediments, precipitation of minerals from solutions, and accumulation of organic materials. Key ways include clastic formation from weathered rock fragments, chemical sedimentation from dissolved minerals, and biochemical processes involving organisms. However, sedimentary rocks do not form from volcanic activity or directly from molten magma, which are processes associated with igneous rocks.
How are chemical and organic rocks classified?
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.
