Coal is a(n) ______ sedimentary rock.Multiple choice question.bioclasticorganicchemicaldetrital

Break Down the Problem

1. Identify the classification of coal among sedimentary rocks.
2. Understand the terms provided in the multiple-choice options.

Relevant Concepts

• Sedimentary rocks are classified into three main types: clastic (detrital), chemical, and biogenic (organic).
• Coal is formed from the remains of plants and is thus classified based on its origin and composition.

Analysis and Detail

1. Clastic (Detrital): These rocks are formed from fragments of other rocks that have been cemented together. This does not apply to coal.
2. Chemical: These are rocks formed from the precipitation of minerals from solution; coal does not fit this category.
3. Bioclastic: This term generally refers to sedimentary rocks formed from biological debris. It is closely related but not the primary classification for coal.
4. Organic: Coal is primarily classified as an organic sedimentary rock because it is formed from decomposed plant material.

Verify and Summarize

The correct classification of coal falls under the organic sediment category, as it is derived from living organisms and their remains.

Final Answer

Coal is an organic sedimentary rock.
