A fracture in minerals refers to the way a mineral breaks when subjected to external forces. It can be described as either conchoidal (smooth and curved) or irregular. The type of fracture can affect the mineral's physical properties, such as its hardness, cleavage, and overall durability.

What are the distinguishing characteristics of cleavage in minerals and how does it affect their physical properties?
Cleavage in minerals refers to the way they break along specific planes due to their atomic structure. The number and angle of cleavage planes can vary, affecting the mineral's physical properties such as its hardness, luster, and ability to split into thin sheets. Minerals with good cleavage tend to break more easily along these planes, while those with poor cleavage may fracture irregularly.
What is the cleavage definition of a mineral and how does it affect its physical properties?
Cleavage in minerals refers to the way they break along specific planes due to their atomic structure. This affects their physical properties by influencing their shape, luster, and overall durability. Minerals with good cleavage break easily along these planes, resulting in smooth surfaces, while those with poor cleavage break unevenly.
Why are some minerals easier to identify than others?
Some minerals have distinct physical properties, such as color, hardness, and cleavage, making them easier to identify. In contrast, other minerals may have similar appearances and overlapping properties, making it more challenging to distinguish them. Additionally, variations in crystal structure and composition can affect the ease of identification.
How many hydrous minerals in mohs scale?
There are several hydrous minerals that are included in the Mohs scale of mineral hardness, such as gypsum, apatite, and fluorite. These minerals contain water in their chemical structure, which can affect their hardness and physical properties.
How will granite affect the soil?
Granite does not significantly affect soil composition or fertility as it is an inert and stable rock. However, when weathered, it can contribute some minerals and trace elements to the soil over time. Additionally, granite can influence soil texture and drainage due to its physical properties.
