How do you tell if mineral has cleavage or fracture?
To determine if a mineral has cleavage or fracture, observe how it breaks. Cleavage is characterized by smooth, planar surfaces along specific directions where the mineral splits easily, reflecting its internal atomic structure. In contrast, fracture results in irregular, jagged surfaces without defined planes. Testing a mineral's breakage pattern can help you identify its cleavage or fracture nature.
Is a crystal structure an essential characteristic of any mineral?
Yes, a crystal structure is an essential characteristic of any mineral. Minerals are defined as naturally occurring inorganic solids with a specific chemical composition and a crystalline structure, which gives them unique physical properties. The arrangement of atoms in a crystal lattice influences the mineral's hardness, cleavage, and other characteristics. Without a defined crystal structure, a substance would not be classified as a mineral.
Why is it not possible to assign a melting temperature to a rock?
Rocks are combinations of minerals which have their own specific melting temperature. The variety of mineral compositions that are possible in a single rock type would make it hard to predict (without knowing the composition) when it would reach liquidus.
Is it possible to get admission in Finland without IELTS?
its it possible or not with out ielts to admission
When a mineral breaks without any regular pattern the break is called?
The fracture can be described (depending on the mineral) as:-Conchoidal fractureSubconchoidal fractureEarthy fractureHackly fractureJagged fractureSplintery fractureUneven fracture

What is silvers cleavage?
In mineralogy, cleavage refers to the way a mineral breaks along planes of weakness due to the arrangement of its atoms. Silver has a characteristic cleavage that is typically described as perfect in one direction, meaning it breaks cleanly and easily along one plane. This cleavage is a result of the crystal structure of silver, which allows it to break along the atomic planes with minimal force.
Compare and contrast a mineral fragment that has one cleavege direction with one that has only fracture?
One that has only one cleavage direction will only fracture in one direction/angle to the matrix of the rock. One that only has fracture would fracture in no specific direction and is probably something like obsidian, which fractures conchoidally, like glass.
What is the base of 1 and two thirds and the height of three fourths?
They are the measurements - although without units - of a prismatic shape.
What does achromatic mean?
Achromatic means "without color". An achromatic lens is a lens that is virtually free from prismatic color distortions.
What type of cleavage do humans have?
Humans have holoblastic cleavage, which is a type of cleavage that occurs in eggs with little yolk. It involves complete division of the egg into smaller cells without the presence of a large yolk mass.

Without a defined crystal structure, a substance would not be classified as a mineral.
Does silver have cleavage or fracture?
Silver has neither cleavage nor fracture because it is malleable and ductile, meaning it can be shaped and stretched without breaking along specific planes like cleavage or irregularly like fracture.
What is a determinate cleavage?
Determinate cleavage is a type of cleavage found in early embryonic development where the fate of each cell is fixed and determined early on. As cells divide, they become committed to specific developmental pathways, leading to the formation of distinct tissues and organs. This type of cleavage occurs in organisms with mosaic development.
The series of cellular divisions by which the zygote becomes a multicellular embryo is known as?
The series of cellular divisions by which the zygote becomes a multicellular embryo is known as cleavage. During cleavage, the zygote undergoes multiple rapid divisions without growth in between, leading to the formation of a blastula or blastocyst.
In how many ways do minerals break?
Minerals break in three main ways: cleavage, fracture, and splintery fracture. Cleavage occurs when minerals break along flat planes defined by their crystal structure. Fracture happens when minerals break irregularly without any specific pattern. Splintery fracture is a type of fracture where the broken piece has sharp edges or splinters.
What are the characteristics of foliated and non-foliated metamorphic rocks?
Foliated metamorphic rocks have a layered or banded appearance due to alignment of mineral grains, exhibit strong cleavage, and are formed under directed pressure. Non-foliated metamorphic rocks do not have a layered structure, show more equidimensional mineral grains, lack cleavage, and are typically formed under contact metamorphism.
