A rock may be brittle.
No, silicon is a brittle material and not ductile.
A material that crumbles or breaks easily is often referred to as brittle. This means that it is prone to breaking, shattering, or crumbling under stress or pressure. Examples of brittle materials include glass and some types of ceramics.
Copper is not considered brittle. It is known for its ductility, malleability, and high tensile strength, making it a valuable material for various applications like electrical wiring and plumbing.
Diamond is considered the most brittle material because even though it is the hardest natural substance, it can still shatter or chip easily due to its unique crystal structure.
physical
Glass is an example of an amorphous solid or non-crystalline material. Glass is typically characterized to be brittle and optically transparent.
The brittle layer of Earth is the crust, which is the outermost layer of the planet. It is composed of solid rock that behaves as a brittle material under stress, leading to the formation of faults and earthquakes.
a brittle is something that breaks easily with out more opposition like bones for instance..

The factors that determine whether a rock behaves as a brittle or ductile material include temperature, confining pressure, strain rate, mineral composition, and presence of pre-existing fractures. Higher temperatures and lower confining pressures tend to promote ductile behavior, while lower temperatures and higher confining pressures favor brittle behavior. The strain rate, mineral composition, and presence of pre-existing fractures can also influence whether a rock will exhibit brittle or ductile behavior.

There are two.
A brittle material fractures without haven a large strain on beforehand. Examples are most ceramics, of extremely hard steel. The opposite is ductile.
A rigid brittle rock is called a "fault rock". This type of rock typically forms along fault lines due to the intense pressure and tectonic forces acting on it, leading to its rigid and brittle nature.
Igneous means that it usually comes from a volcano. For example, igneous rock is rock from a volcano
