The parallel arrangement of mineral grains in a rock that gives it a striped appearance is called foliation. This typically occurs in metamorphic rocks due to the alignment of minerals under pressure and heat, resulting in distinct bands or stripes. Foliation can provide clues about the rock's history and the direction of metamorphic forces.

What does a mineral with a nonmetallic silky luster have?
A mineral with a nonmetallic silky luster is likely to be fibrous in structure, such as asbestos or satin spar gypsum. This type of luster is caused by the arrangement of fine parallel fibers that reflect light, creating a smooth and shiny appearance. Minerals with this luster are often valued for their unique texture and appearance.
What arrangement of atoms in a repeating pattern in a mineral causes the formation of?
The arrangement of atoms in a mineral sample can cause the formation of crystals.
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.
Step like cleavage is a property of what mineral?
Step-like cleavage is a property of the mineral mica. Mica minerals exhibit a planar arrangement of atoms that allow them to easily separate along flat surfaces, giving them a distinctive step-like appearance when broken or cleaved.
What is an example of striation?
An example of striation is the parallel lines found on rocks and minerals, caused by the alignment of mineral grains during their formation or deformation. Another example is the visible lines on muscles that result from the arrangement of muscle fibers.
