Organic sedimentary rocks are primarily composed of organic materials, such as plant debris or the remains of marine organisms. They typically have a layered appearance and may contain fossils, which provide insights into the environment of deposition. Common examples include coal, formed from compressed plant material, and certain types of limestone, which can originate from shells and coral. These rocks often indicate past biological activity and can be associated with specific depositional environments, such as swamps or shallow marine settings.
What else can I help you with?
Are sedimentary rocks formed when sediments are compacted by extreme pressure?
Clastic and organic sedimentary rocks like conglomerate, coal, some limestones, and shale, are formed under pressure from overlying sediments.
What is organtic sedematary rock?
Organic sedimentary rock is a type of sedimentary rock that forms from the accumulation and lithification of organic materials, such as plant debris, shells, or coral. Examples include coal, limestone, and some types of shale. These rocks often contain fossils and can provide valuable information about past environments.
What is the only sedimentary rock type that can be formed from things once alive?
The only sedimentary rock type that can be formed from things once alive is organic sedimentary rock, specifically coal. Coal is formed from the accumulation and compaction of plant material, primarily in swampy environments, over millions of years. Other examples of organic sedimentary rocks include some types of limestone, which can form from the remains of marine organisms.
What types of rock are Sedimentary rock?
Some types of sedimentary rocks include limestone, sandstone, shale, and conglomerate. Sedimentary rocks form through the accumulation and lithification of sediment such as minerals, organic materials, and rock fragments that are transported and deposited by water, wind, or ice. The characteristics and composition of sedimentary rocks can provide valuable information about Earth's history and processes.
What type of rock forms when material from dead plants and animals is deposited and harden into rocks?
Organic sedimentary rock forms when material from dead plants and animals (organic matter) gets deposited and hardens into rocks over time. Examples include coal and some types of limestone.

What are examples of organic sedimentary rock?
Examples of organic sedimentary rocks include coal, which forms from the accumulation and compaction of plant remains, and limestone, which can contain organic debris such as shells and coral. Organic sedimentary rocks are derived from the remains of living organisms.
What are clasts?
Clasts are individual pieces of rock or mineral fragments that make up a sedimentary rock. They can vary in size and shape, ranging from tiny grains to large boulders, and are important in determining the characteristics and composition of the sedimentary rock.

The characteristics and composition of sedimentary rocks can provide valuable information about Earth's history and processes.
Is limestone an example of a detrital sedimentary rock?
It can be. Some limestone is formed from the precipitation of calcite from saturated solutions, and is considered a chemical sedimentary rock. Other limestone that consists largely of the skeletal remains of marine organisms is considered bio-clastic, a cross between an organic and a detrital sedimentary rock. Typical detrital sedimentary rocks are those composed mostly of particles of pre-existing rock, although organic matter may be included; examples would be sandstone, shale, and conglomerate.
What type of rock forms when material from dead plants and animals is deposited and harden into rocks?
Organic sedimentary rock forms when material from dead plants and animals (organic matter) gets deposited and hardens into rocks over time. Examples include coal and some types of limestone.
Why is coal not considered to be a rock?
Coal is typically formed from the remains of plants and organic matter that have undergone a specific process called coalification. While coal does contain some components found in rocks, it is primarily made up of organic materials and has unique properties and characteristics that differentiate it from typical rocks, such as sedimentary rocks like shale or sandstone. This distinction is based on the specific conditions under which coal forms and its composition.
Where can you find a sedimentary rock?
Examples of sedimentary rock include:BauxiteLimestoneDolostoneBrecciaConglomerateShaleMudstoneBituminous CoalSandstoneHaliteGypsumChalkCoquinaLateriteArkoseGraywackeClaystoneSiltstoneChertTypes include clastic (cemented sediment particles), non-clastic (chemical precipitates or evaporites), and organic (from organisms, e.g. coal). Some will further divide sedimentary rocks into another type called bioclastic, rocks formed from clasts of organic matter (like sea shells).
