Sedimentary Rock
Sedimentary rock is formed when minerals and other organic materials are deposited in layers by water, ice, wind, or mass movement such as mudslides.

What is chemical formula for kieselguhr?
Kieselguhr is a rock not a chemical compound with a chemical formula.
How are sedimentary rocks are made?
Sedimentary rocks are made by the majority of the crust are covered by a thin veneer of loose sediment, and the rock which is made as layers of this debris get compacted and cemented together.
Are sedimentary rocks that form when minerals come out of a solution classified as porphyritic?
No. I believe they are called chemical precipitate sedimentary rocks. Yes, I'm sure they're called that. Absolutely! Porphyritic is a term usually applied to igneous rocks, having to do with mineral formation and rock texture.
Why are Sedimentary rocks are not found on the Moon?
There could be sedimentary rocks on the Moon, the processes forming them would be different from those on the earth but it is possible that there are processes moving and layering Moon dust which could be regarded as a sediment.
However, in general there is no erosion or deposition happening on the Moon as it does on Earth and therefore no rocks formed as a result of these processes.
What role does carbon dioxide play in forming limestone as a chemical precipitate?
The reaction is:
Ca(OH)2 + CO2 = CaCO3 + H2O
What is a brief summary of the section sedimentary rock features from the earth space science book?
depositional environments is the place or setting in which sediments is deposited. oceans, rivers, deltas, and beaches are all common depositional. each of the depositional environment has different characteristics that create specific structure in sedimentary rock.
How expensive is a limestone fireplace?
A limestone fireplace is moderately expensive. Limestone fireplaces range on different prices depending on what you use to make them. The average price is $500.
Do grikes in limestone form mainly by wind or water?
Grikes in limestone primarily form due to water erosion rather than wind erosion. Water seeping into the limestone gradually dissolves and widens vertical joints and fractures, creating the grikes. Wind can contribute to weathering and desiccation of the limestone, but it is not the primary agent responsible for the formation of grikes.
Is schist a clastic sedimentary rock?
No, schist is a metamorphic rock formed from the alteration of pre-existing rock under high pressure and temperature. It is characterized by its foliated structure. Clastic sedimentary rocks are formed from the accumulation and lithification of fragments of pre-existing rocks or minerals.
Does sedimentary rock form from the cooling of magma?
No. Igneous rock forms from the cooling of magma.
What processes must a sedimentary rock go through to become a metamorphic rock?
what processes must sedimentary rock go through to become a metamorphic rock
What type of sedimentary rock is sandstone?
Sandstone is a type of sedimentary rock that is composed of sand-sized grains of minerals, rock, or organic material. It is typically formed in environments where sand accumulates and is compacted over time, such as beaches, rivers, or deserts.
Rock that is made from cemented animal bones and shells is what organic limestone is.
Specifically, the term "organic" indicates that the rock in question contains parts from a once-living animal. Hard parts such as bones and shells may cement together. The minerals - such as calcite - which make up these hard parts will form into limestone. In comparison, chert will form from the silica-based skeletons of microorganisms that die in such watery environments as lakes and oceans.
What are 3 things that cause sedimentary rock to change to metamorphic rock?
Sedimentary rock is changed to metamorphic rock using:
1. High pressure
2. High heat
3. A large amount of time
What does sedimentary rock and fossils have in common?
Most organic matter(living plants,insects,animals etc,) gets fossilized by the layers of sediments and with heat and pressure in millions of years become fossils.This process of preservation is not possible in other types of rocks.
Does sedimentary rock contain lithosphere?
You reversed it.
The lithosphere contains rock: igneous, sedimentary, and metamorphic.
The prefix litho- means rock or stone. This prefix is also used in the word lithography, which is a type of printing using stone printing plates.
How is sedimentary rock formed?
#2. Organic sedimentary rocks like some limestones and coal are formed largely from the remains of once living organisms. Chalk and fossiliferous limestones are formed from the skeletons of marine organisms. Coal is formed from vegetation that previously existed in swampy and marshy waterlogged soils which prevented their full decay after their death. As their remains piled up and were covered by more and more deposits, they gradually underwent compaction and cementation as described in #1. above.
#3. Sedimentary rocks can also form when minerals in a body of water have so saturated the water that they precipitate out, like a cloud that is so full of moisture that it pours out rain. Some limestones are formed in this manner as the mineral calcite precipitates out of a saturated solution and undergoes the process of compaction and cementation. The supersaturated solutions can also be caused by evaporation of a body of water high in mineral content. As the water evaporates, the mineral percentage of the remaining solution becomes higher and higher, until the mineral crystallizes. Rocks such as rock salt and rock gypsum are formed in this manner. Sedimentation from precipitation and evaporation form rocks called chemical sedimentary rocks.
What are Factors affecting the toughness of rock?
The factors affecting toughness of rock includes;
1. Rock Texture.
2. Rock Structure.
3. Weathering activities.
4. Metamorphism.
What gives quartz sandstone its color?
Pure quartz is a colorless mineral, and so a pure quartz sandstone will appear white due to multiple reflections and refractions between grains. However, impurities in the sandstone may give it some other color. What color it turns out as depends on the impurities. For example, iron oxide will produce a red sandstone.
How can a sedimentary rock change into a different sedimentary rock?
by how they can used erosion and weathering
What music group did angie stone belong to?
Angie Brown Stone (born December 18, 1961) was part of the rap group Sequence back in the late 70's and early eighties. She also was in a group called Vertical Hold in the early to mid 90's.
What are sedimentary rocks laid down in?
Sedimentary rock formations are those which are formed by layer upon layer of sediment being laid down by natural forces. It is the stone in which history is hidden.
