foliation
Clay minerals structure themselves in sheets or layers, and are silicate minerals. This characteristic makes clay feel slippery when wet, as the flat individual mineral grains easily slide in a parallel fashion from one another.

Clay minerals structure themselves in sheets or layers, and are silicate minerals. This characteristic makes clay feel slippery when wet, as the flat individual mineral grains easily slide in a parallel fashion from one another.
Minerals do have zones of weakness. They are known as cleavage planes. It is the tendency for minerals to break along flat, parallel surfaces. They come in a variety of categories, but it is ultimately where the mineral will break if struck. It cal be basal, prismatic,cubic, rhombohedral, octahedral, or dodecahedral.
On a flat Euclidean surface, parallel lines cannot meet. On a sphere, parallel lines CAN meet.

It has a regular arrangement of atoms.
A quadrilateral with two parallel sides is a trapezoid.
