This is called cleavage.
The rock you are referring to is most likely shale. Shale is a sedimentary rock that often exhibits iridescence due to the presence of minerals like mica or pyrite. Its characteristic property of peeling off in layers is due to its fissile nature, which allows it to easily split into thin sheets.
The light-colored igneous rocks rich in aluminum, potassium, silicon, and sodium are called felsic rocks. These rocks have a high content of minerals like quartz, feldspar, and muscovite, giving them their characteristic light color. Examples of felsic rocks include granite and rhyolite.
Steam changing to liquid water is an example of condensation, which is the process of a gas turning into a liquid. This occurs when the temperature of the gas decreases to the point where it can no longer maintain its gaseous state and transforms into a liquid.
Biotite Mica would fit this category as would Muscovite, native to Russia as the name implied. (Sheets) oif semi-transparent mica can be peeled right off. the mineral is useful in electrical condensers and also as a form of glass substitute that is heat-resistant, called Isinglass. it is neither Eisen-(Iron) nor Glass, but the name stuck.
The scientific study of the physical characteristics of rocks is called petrology. It focuses on the composition, classification, and origin of rocks based on their physical and chemical properties.
A phenotype. If this is for Biology.
In Russia they made windows out of a type of mineral called Muscovite.
A substance that is formed from one type of atoms with a characteristic set of physical and chemical properties is called an element.
The characteristic of matter you are referring to is called a physical property. The ability to melt is an example of a physical property exhibited by ice, where it changes from a solid state to a liquid state when heated.
The characteristic obtained by changing the state of matter, such as the ability to melt, is called a physical property. Physical properties describe the state of a substance without changing its chemical composition. In the case of melting, the physical property is the temperature at which a solid turns into a liquid.
Someone from Moscow, Russia is known as a Muscovite.
When you can observe something's characteristics, they are called physical traits. These are the things you can see, hear, smell.
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance.
Then the physical characteristic of a substance change, it is called a change in state. This most commonly occurs when a substance is heated or cooled. The states that substances are solid, liquid and gas. A common example would be water: ice (solid), water (liquid), and steam (gas).
A characteristic that can be measured or detected by the senses is called a physical property. Physical properties include color, shape, size, and texture, among others.
phenotypeThe physical appearance of a trait is called a phenotype, not to be confused with a genotype( which is your genetic makeup) The way I remember is phenotype and physical both start with a p, and genotype and genetic both start with a g.
A physical trait of an organism is called a phenotypic trait. It refers to any observable characteristic or feature of an organism's physical appearance or behavior. Phenotypic traits can be influenced by genetic factors, environmental factors, or a combination of both.
