What organic sedimentary rock is made of microscopic shells?
Limestone and chalk.
What is an organic sedimentary rock made of microscopic shells?
An organic sedimentary rock made of microscopic shells is called limestone. Limestone is mainly composed of calcium carbonate derived from the accumulation of marine organism shells such as shells of foraminifera, coral, and mollusks. Over time, these shells compact and cement together to form solid rock.
Is limestone from shells chemical organic or clastic?
Limestone made from shells would be an organic sedimentary rock.
What type of stone is made up of microscopic particles of shells that have been cemented together?
Limestone is a type of stone made up of microscopic particles of shells that have been cemented together. This sedimentary rock is formed over millions of years as the shells accumulate and compress into solid rock.
Is limestone that is made from shells a organic rock?
Yes, mostly gravel from a landslide, and organic rocks
What is an organic sedimentary rock composed of cemented shells?
An organic sedimentary rock composed of cemented shells is called limestone. Limestone is primarily made up of the mineral calcite, which is derived from the shells of marine organisms like coral and mollusks. Over time, these shells accumulate and compress to form solid rock.
What are some examples of organic rock?
Examples of organic rocks include coal, which forms from compressed plant material, and limestone, which can contain fossilized remains of marine organisms like shells or coral. Another example is chalk, composed mainly of microscopic shells from plankton.
What is an example of a sedimentary rock that is biochemical (organic)?
Limestone and chalk are formed from organic material Limestone - Clastic shell fragments Chalk - Microscopic shells of calicum carbonate plates formed by single celled algaes Chert - Microscopic siliceous organisms, recrystallized silica
What does organic rock mean?
"Organic rock" refers to a type of rock formation that is made up of natural materials such as shells, fossils, or organic debris. These rocks can provide important information about past environments and geological processes.
Chalk formed from sediments made of skeletons of microscopic living things in the ocean must be a?
Chalk formed from sediments made of skeletions of microscopic living things in the ocean must be a(n) organic rock.
What rocks was formed skeleton and shells of sea animals and plats in the ocean?
limestone. A rock made up mainly of the shells or fragments of shells of megascopic (clams, oysters, snails) animals is a coquina. If the rock is composed of the shells (tests) of microscopic plants and animals it may be called chalk. Limestone can be a hardened chemical precipitate of CaCO3 without an organic source, and take many forms: oolite for example.
Describe a few rocks that are composed of nonmineral matter?
Coal is a rock made from organic matter, primarily plant material. Chalk is a soft rock made of calcium carbonate from the shells of microscopic ocean organisms. Obsidian is a volcanic glass rock formed from lava that cools too quickly for mineral crystals to grow.
