Coal is an organic sedimentary rock. It has conchoidal fracture. The composition is so different because coal, depending on age, contains mostly carbon as it is formed from plant cellulose. It is different because it is carbon, as opposed to a common mineral like other sedimentary rocks.
Sedimentary rocks are formed from the accumulation and compression of sediments, such as sand or mud, over time. This process sets them apart from igneous rocks, which form from the cooling and solidification of molten rock, and metamorphic rocks, which are formed from the alteration of existing rocks due to heat and pressure. Sedimentary rocks often contain fossils and layers, making them unique in their composition and appearance.
The three types of rocks - igneous, sedimentary, and metamorphic - are different in terms of how they are formed. Igneous rocks are formed from the cooling and solidification of molten material, sedimentary rocks are formed from the accumulation and cementation of mineral and organic particles, while metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure within the Earth's crust.
Nitrogen (symbol N2) makes up 78% of the composition of air.
Sedimentary rocks are composed of particles that have been eroded, transported, and deposited by wind, water, or ice. These particles can include minerals, organic material, and fragments of other rocks. Over time, these particles become compacted and cemented together to form solid sedimentary rocks.
Fine-grained sedimentary rocks are typically smooth in texture due to their small grain size, which makes it difficult to discern individual grains with the naked eye. The smoothness can vary depending on factors such as the mineral composition and the level of compaction of the rock.
The way in which they were formed.
Each salt has a different chemical composition and consequently different chemical and physical properties.

The chemical composition of the star.
Yes, sedimentary rocks are typically formed from the accumulation and lithification of inorganic materials such as minerals, shells, and organic debris. Organic matter can be present in sedimentary rocks, but it generally makes up a small percentage of the rock's composition.
Limestone makes up ten percent of all sedimentary rocks.
Your question makes little sense, "a sedimentary rock" can be of virtually any size.
95or all fossils found. Sedimentary rock makes up ¾ of the earth's surface.
Sedimentary
The three types of rocks - igneous, sedimentary, and metamorphic - are different in terms of how they are formed. Igneous rocks are formed from the cooling and solidification of molten material, sedimentary rocks are formed from the accumulation and cementation of mineral and organic particles, while metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure within the Earth's crust.
Examples:- the state of matter- the chemical composition- the chemical properties- the physical properties
Sedimentary rocks are simply the result of erosion, deposition, and cementation of different types of rock and there particles. They almost ALWAYS have layers that you can clearly see, because of being pushed together. Sometimes they may even have fossils in them.
