from dead plants
Clastic sedimentary rock forms when fragments of preexisting rocks are compacted or cemented together. Organic sedimentary rock forms from the remains of plants or animals. Chemical sedimentary rock forms when minerals precipitate from a solution or settle from a suspension.
they form
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.
sedimentary rocks can be classified by detrial, chemical ,or organic
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.
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.
Yes. Oil forms in sedimentary rock from organic material that settle with the original sediment.

Sedimentary rocks have beds/strata. They are made from decomposed materials of other rocks. Plus they they have 3 forms: clastic = compacted or cemented rock particles (consolidated); precipitated = dissolved minerals deposited as H2O (water) cools or evaporates; organic = formed from organic matter (coal) or the activities of organisms (amber). Clastic sedimentary rocks are the most common, they are either sorted or unsorted. Precipitated sedimentary rocks can be crystals or massive. Organic sedimentary rocks usually vary.

Sedimentary rocks formed from the remains of plants and animals are called organic sedimentary rocks. Examples include coal, formed from the remains of plants, and limestone, formed from the shells of marine organisms.
sedimentary and metamorphic rocks
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.
The material comprising the rocks coal and limestone are derived from organisms. Therefore, they are classified as organic sedimentary rocks.
