Chemical rocks are based on their composition ie. what they are composed of. What separates chemical from biochemical is whether there is any organic matter like shells or plant fragments present.
they are classified by how they are classified
Both organic sedimentary (like coal) and chemical sedimentary (like rock salt) rocks are not composed of particles of other rocks. They are different because organic rocks are composed of the remains of living things but chemical rocks are formed by inorganic processes such as evaporation.
by their kingdoms by a five knigdom classification system which classifies all organisms
Organisms are classified based on their various similarities, and also based upon their relationship to other organisms.
Gold is usually found in metamorphic rock but can also be found in sedimentary rock. In deep mines, quartz rock is found in association with gold.
Rocks are classified as igneous, sedimentary, or metamorphic based primarily on their origin and how they were formed. Igneous rocks are formed from cooled magma or lava, sedimentary rocks are formed from the accumulation of sediments, and metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure.
A rock is an agglomeration of different minerals. Minerals are classified into categories based on their chemistry: oxides, sulphides, silicates, carbonates etc. Rocks are classified primarily by the process that formed them: igneous, sedimentary, or metamorphic.
Igneous rocks are classified based on mineral composition and texture, metamorphic rocks are classified by texture and mineral composition, and sedimentary rocks are primarily classified by their grain size and composition. These classifications help scientists understand the origin and characteristics of each type of rock.

No, igneous rocks are not classified by their shape. They are primarily classified based on their origin (either intrusive or extrusive) and their texture (coarse-grained, fine-grained, glassy, etc.). Shape or form is not a major factor in the classification of igneous rocks.
No, metamorphic rocks are not classified according to their shape. Instead, they are classified based on their mineral composition and texture, which reflects the conditions under which they formed. Common classifications include foliate, which has a layered or banded appearance, and non-foliate, which does not exhibit layering. The classification primarily focuses on the processes of metamorphism and the resulting characteristics of the rocks.
Clastic sedimentary rocks are primarily classified based on the size of the particles they are composed of. These rocks are categorized into different groups such as gravel, sand, silt, or clay, depending on the size of the fragments they contain. The classification helps in understanding the environment in which the rocks were formed and the processes involved in their deposition and lithification.
Igneous rocks can be classified by their method of formation and by their mineralogy.
No, sedimentary rocks are classified based on their grain size, composition, and texture, not by whether they are foliated or nonfoliated. Foliation is a feature typically found in metamorphic rocks, not sedimentary rocks.
Rocks are classified into two main groups based on how they are formed: igneous rocks, which are formed from cooling and solidifying magma or lava, and sedimentary rocks, which are formed from the accumulation and compression of sediments.
Sedimentary rocks are classified based on their mineral composition, grain size, texture, and the way they were formed. The three main types of sedimentary rocks are clastic, chemical, and organic. Clastic rocks are made up of broken fragments of other rocks, chemical rocks form from precipitation of minerals from water, and organic rocks are formed from the accumulation of plant and animal remains.
Detrital sedimentary rocks are primarily classified based on the size, shape, and composition of the sediment particles that compose them. Common classifications include sandstone (made of sand-sized particles), siltstone (silt-sized particles), and shale (clay-sized particles). The mineral composition, such as quartz or feldspar content, also plays a crucial role in their naming and classification.
