What are 2 examples of organic rocks?
Organic sedimentary rocks form from the accumulation of plant or animal debris. Examples include: chalk, coal, diatomite, some dolomites, and some limestones.
What are the two types of organically formed sedimentary rocks?
Coquina, bioclastic limestone, and skeletal limestone are also technically organic sedimentary rocks but are usually grouped with the other limestones as being chemically precipitated.
Which is an example of an organically derived sedimentary rock?
Organic sedimentary rocks form from organically derived sediments. Coal is an organic rock composed of the remains of plants deposited in coastal swamps. The sediments in some organic rocks (for example, fossiliferous limestone) undergo cementation; other sediments may only be compacted together (for example, coal).
How are organic rocks classified?
Chemical rocks are classified based on their mineral composition. The sediments in some organic rocks (for example, fossiliferous limestone) undergo cementation; other sediments may only be compacted together (for example, coal). Geologists classify organic rocks by their composition.
Which is an example of an organic sedimentary rock?
Rich enough in carbon to burn, coal is an organic sedimentary rock that is a widespread and important fuel source. Coquina, bioclastic limestone, and skeletal limestone are also technically organic sedimentary rocks but are usually grouped with the other limestones as being chemically precipitated.
How are the different types of rocks formed?
There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material.
How are energy resources formed in sedimentary rocks?
Natural gas, oil, coal, and uranium, and other energy resources are formed in and come from sedimentary rocks.

Which is an example of an organic material?
Organic material containing carbon can become coal. Here are examples: Sedimentary basins are areas where sedimentation occurred on a large scale. Examples include: Rift basin – Examples are San Luis, Espanola, and Albuquerque basins of the Rio Grande Rift and the Fundy Basin in Canada
