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.
Is rock organic?
Rock salt is a chemical sedimentary rock.
Is rock salt organic?
Rock salt is a naturally occurring mineral composed of sodium chloride and is not considered organic. It is not derived from living organisms and does not meet the criteria for organic certification.
Is the sedimentary rock that forms when minerals precipitate from a solution and settle from a suspension organic chemical or clastic sedimentary rock?
The sedimentary rock formed from minerals precipitating from a solution is called chemical sedimentary rock. It is formed through processes such as evaporation or chemical reactions, without the involvement of organic material or clastic particles.
What igneous rock has no visible crystals?
Obsidian is an igneous rock that has no visible crystals due to its rapid cooling process, which prevents crystal formation. It is often dark in color and has a glassy appearance.
Is a rock gypsum a clastic chemical or organic rock?
chemical
Is a rock salt a organic or a clastic or a chemical?
Rock salt is a chemical sedimentary rock.
Is obsidian metamorphic igneous or sedimentary?
Obsidian is an igneous rock.
What rock can be a chemical or organic rock?
Limestone is a type of rock that can be either chemical or organic in nature. Chemical limestone is formed through the precipitation of calcium carbonate, while organic limestone is made up of the remains of marine organisms like shells and coral.
What does rock group does obsidian belong to?
Obsidian is in the Igneous rock group.
What do a coal rock and a obsidian rock have in common?
Both coal and obsidian are types of rocks that are formed from cooling molten material. However, coal is primarily composed of organic matter such as plant material, while obsidian is a naturally occurring volcanic glass with a dark color and smooth texture.
Is limestone an organic and chemical sedimentary rock?
Limestone is a chemical sedimentary rock formed from the precipitation of calcium carbonate. It is primarily composed of mineral calcite, which is organic in origin but can also form through inorganic processes. So, limestone is considered both a chemical and organic sedimentary rock.
What is obsidian's chemical formula?
Obsidian is volcanic glass, a mixture and as such has no chemical formula.
How can you distinguish between a chemical sedimentary rock and a organic sedimentary rock?
A sedimentary organic rock is living or was once living like a coral. Chemical is chemically made and is usually man cut.
Is obsidian extrusive rock?
No. Obsidian is volcanic glass. Glass is amorphous and thus noncrystalline.
Is organic rock a type of sedimentary rock?
ORGANIC SEDIMENTARY ROCK`s : Is a type of sedimentary rock because sedimentary rock has three types of sedimentary rock called clastic , chemical , and organic sedimentary rock so yes ORGANIC SEDIMENTARY ROCK is a type of sedimentary rock..........................................
Is rhyolite clastic organic or chemical?
It is none of these. Clastic, organic, and chemical are terms for classifying sedimentary rock. Rhyolite is igneous.
