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.

Rocks are classified as igneous sedimentary or metamorphic based primarily on their?

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.


How are rocks related to minerals What is the difference in how rocks and minerals are classified?

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.


How are igneous metamorphic and sedimentary rocks classified?

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.

Was igneous rocks were classified by their their origin texture and shape?

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.


Clastic sedimentary rocks are primarily classified on the basis of?

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.


what are igneous rock classified based upon?

Igneous rocks can be classified by their method of formation and by their mineralogy.


Are sedimentary rocks classified by foliated and nonfoliated?

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.


What two ways are rocks classified into?

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.


How are sedimentary rocks classified?

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.


How are igneas rocks classifled?

Igneous rocks are classified based on their mineral composition, texture, and origin. They can be divided into two main categories: intrusive rocks, which form from magma cooling beneath the Earth's surface, and extrusive rocks, which form from lava cooling on the Earth's surface or in the air. Within these categories, igneous rocks can then be further classified into specific types based on their mineral content and texture.
