Rocks are exposed to the elements and undergo weathering. This can cause the minerals that they are composed of and that are exposed at the surface to become discoloured which can make them hard to identify. A geologist will often use a geological hammer to crack the rock sample to see the fresh, unweathered minerals.

What is the tendency of a mineral to break along planes of weakness producing smooth parallel breaks known as?

Cleavage is the tendency of a minerals to break along flat surfaces. It means that the make up of the mineral is uneven, dense on one side and not dense in the other, causing the mineral to break along flat surfaces. The tendency of a mineral to break irregurlary is fracture.

What is the difference between mineral cleavage and mineral fracture.?

Cleavage is the breaking of a mineral along flat surfaces. Fracture, on the hand is just the chipping or "fracture" of a mineral.Cleavage is the tendency to break along flat surfaces, and fracture is the tendency of a mineral to break into irregular pieces.


Scientists use this to determine a minerals resistance to being scratched?

A mineral's resistance to being scratched is known as it's hardness. You can determine hardness by scratching it with another material whose hardness is already known. If it can be scratched, then the hardness is lower. If the unknown leaves a scratch on the known material, then its hardness is higher.


What is the ability of a mineral to break along preferred directions called?

The ability of a mineral to break along preferred directions is called cleavage. Cleavage is a result of the arrangement of atoms within the mineral structure, which causes it to break in certain directions more easily than others.


What is the source of mineral fragments in soil?

Mineral fragments in soil come from the weathering and breakdown of parent rock material over time. Physical, chemical, and biological processes break down larger rock particles into smaller mineral fragments, which become part of the soil composition. These mineral fragments provide essential nutrients for plants and help determine soil properties.
