What is a common mineral that breaks with rough or jagged edes?
Quartz is a common mineral that breaks with rough or jagged edges. This is due to its brittle nature and the way its atomic structure breaks along planes of weakness when subjected to stress.
What rock is actually glass and has sharp edges?
Obsidian is a type of volcanic glass that is formed when lava cools rapidly. It typically has a black or dark brown color and has sharp edges due to its lack of crystalline structure. Obsidian is often used in making tools and weapons due to its sharpness.
When a mineral breaks with rough edges what is that called?
When a mineral breaks with rough edges, it is called a "fracture." This is different from cleavage, which is when a mineral breaks along smooth, flat planes. Fracture can be described as conchoidal (shell-like), uneven, or fibrous.
What is a volcanic rock that northeastern California Indians used to make weapons tools jewelry and traded?
Obsidian is a volcanic rock that northeastern California Indians used to make weapons, tools, and jewelry. It was also a valuable item for trade due to its sharp edges and distinctive appearance.
The edges of most lithospheric plates are characterized by?
The edges of most lithospheric plates are characterized by either being divergent (moving apart), convergent (coming together), or transform (sliding past each other) boundaries. These interactions can lead to various tectonic activities such as earthquakes, volcanic eruptions, and mountain formation. The type of boundary and the resulting geological features depend on the direction and speed of the plate movements.
What is Volcanic glass with no crystaline structure and breaks with very sharp edges?
BASALTIN
What is volcanic glass with no crystaline strucutre that breaks with very sharp edges?
Volcanic glass with no crystalline structure is known as obsidian. It forms when lava cools quickly, preventing the formation of crystals, resulting in a smooth, glassy texture. Obsidian is known for its sharp edges when fractured, making it useful for tools and cutting instruments in ancient times. Its unique properties also make it popular in jewelry and decorative items today.
What happens when an amorphous solid breaks?
The solid breaks at random places. Apex. thanks guy below for leading me to this answer

The edges of most litospheric plates are characterized by?
frequent volcanic activity
What type of igneous rock is this dark volcanic rock shiny like glass with sharp edges?
The dark volcanic rock you are describing is likely obsidian. Obsidian is a naturally occurring glass formed from rapidly cooled lava, which gives it a shiny appearance and sharp edges. Its lack of crystalline structure is what differentiates it from other igneous rocks, and it is often used for cutting tools and decorative items.

What is the process called that roughens the edges of rocks and causes grooves and breaks in them?
That depends on what the object with rough edges and grooves is.
How does fluorite break?
Fluorite typically breaks in a conchoidal fracture pattern, which means it breaks with curved or shell-like surfaces. This is due to its crystal structure and cleavage planes. When struck, fluorite can also exhibit a brittle fracture, breaking into irregular shapes with sharp edges.
Why is glass so sharp?
Glass is sharp because of its molecular structure. When glass breaks, it forms jagged edges and sharp points because the molecules in glass are arranged in a way that allows them to easily break apart into sharp pieces.
What happens when Ice breaks off from the edges of Antarctica?
it will float to warmer Waters and eventually melts.
