Which mineral shows no cleavage has a hardness of 6.5 and a composition of SIO?
The mineral that fits this description is quartz. It has a hardness of 7 on the Mohs scale, does not show cleavage, and has a chemical composition of SiO2.
Which mineral shows no cleavage has a hardness of 7 and a composition of SiO2?
The mineral you are describing is quartz. Quartz has a hardness of 7 on the Mohs scale, meaning it is quite hard, and it does not exhibit cleavage, instead breaking with a conchoidal fracture. Its chemical composition is silicon dioxide (SiO2). Quartz is one of the most abundant minerals in the Earth's crust and is commonly found in various geological environments.
What can cleavage and fracture do to a mineral?
Cleavage and fracture describe how a mineral breaks. Cleavage shows the tendency of a mineral to break along specific planes due to its crystal structure, while fracture refers to irregular breakage patterns. Cleavage can create smooth surfaces, aiding in mineral identification and classification, while fractures can vary in appearance, from conchoidal (shell-like) to uneven.
Which characteristics do samples of mineral pyroxene normally exhibit?
Mineral pyroxene typically exhibits a monoclinic or orthorhombic crystal structure, characterized by a prismatic habit and often forms elongated crystals. It commonly displays a vitreous to dull luster and can vary in color, ranging from dark green to black, and sometimes brown or gray. Pyroxene has a hardness of 5 to 7 on the Mohs scale and shows two distinct cleavage planes at nearly 90-degree angles, which is a key identifying feature. Additionally, it often contains iron, magnesium, and calcium in its composition, contributing to its varied properties.
What map shows minerals of an area?
A geological map shows the distribution and types of minerals in an area. These maps are valuable for understanding the mineral composition of a region and can be used for mineral exploration, land use planning, and environmental assessment.

What a cleavage mineral?
when a mineral is broken, if it breaks with smooth shiny sides, then it shows cleavage. If it breaks with rough, uneven sides then it shows fracture.Cleavage is caused by ___________.a)The shape of the mineral.b)The color of the mineral.c)Atomic structure of a mineral.d)The way the mineral is dropped.Undo

An unknown mineral scratches glass but will scratch quartz What measure om the mohs scale shows its hardness?
The unknown mineral is not a mineral, or the pieces being scratched or doing the scratching are not freshly fractured or cleaved surfaces.

Why does cleavage occur?
Cleavage means to Split.Cleavage is most often used with the following 3 meanings:MITOSIS: a phase during Mitosis when cells split and multiplyGEOLOGY: The splitting of a complex crystal/mineral formation into a simpler oneINFORMAL USE: The viewable split between a woman's breasts
What determines how mineral cleaves?
when a mineral is broken, if it breaks with smooth shiny sides, then it shows cleavage. If it breaks with rough, uneven sides then it shows fracture.Cleavage is caused by ___________.a)The shape of the mineral.b)The color of the mineral.c)Atomic structure of a mineral.d)The way the mineral is dropped.Undo
Graphite is a mineral that does not leave a clear streak?
well i really don't know sorry. Here are some useful things close to that... 1. Mica shows clear cleavage. 2. Hardness is a measure of how easily a mineral can be scratched. ill tell you as soon as possible when i figure it out! Thank you

What is the scientific definition for cleavage?
Mineral Cleavage:Cleavage is one characteristic of minerals that refers to the tendency to split along planes of weakness. Female Cleavage:The space between a woman's breasts is her cleavage. When women wear low-cut clothing, their cleavage shows. For example, a low-cut wedding dress shows cleavage Plumber's Cleavage:Plumbers often exhibit their cleavage when they squat to fix your sink. It is best to look away. A word about the word:"Cleave" is one of the few words in the English language that is its own antonym. "To cleave" can mean "to hold fast to" and "to break or cut away from". Cleavage describes the break in a mineral. It is one of the physical properties that people test to identify minerals. Cleavage means that a mineral breaks cleanly, with no jagged edges. If it does have jagged edges than it is a fracture. When a mineral has cleavage then that means the it has a cubic structure, and therefore, will break cleanly and smoothly. Let's say that you smash a rock and it breaks everywhere, and has rough, jagged edges. It has fractured. It also has no cleavage. If you break another one and it's sides when broken are smooth and straight, it has cleavage.Cleavage usually refers to the exposure or partial exposure of the separation, or lack of, between a woman's breasts. It can also refer to a division between two groups of people or things.
