When a rock with a portruding edge that is less than ninety degrees in angle is struck on that edge and produces a conical shaped chip or "flake", leaving behind a concave flake scar where the material was removed from the rock, that is a conchoidal mineral.
Minerals break in the main two ways cleavage and fracture. Cleavage is breaking in flat planes but fracture is more uneven even unpredictable. The hardest mineral to break would be the diamond, which is placed at a ten on Moh's hardness scale.
Minerals break in three main ways: cleavage, fracture, and splintery fracture. Cleavage occurs when minerals break along flat planes defined by their crystal structure. Fracture happens when minerals break irregularly without any specific pattern. Splintery fracture is a type of fracture where the broken piece has sharp edges or splinters.
Two ways of chemical weathering are oxidation and hydrolysis. Oxidation occurs when oxygen reacts with minerals in rocks, causing them to break down. Hydrolysis involves the reaction of minerals with water, leading to their decomposition into new minerals. Both processes contribute to the breakdown of rocks over time.
Two important causes of chemical weathering are oxidation, which occurs when minerals are exposed to oxygen and chemically react with it, and hydrolysis, which happens when minerals interact with water molecules and break down into new compounds. These processes can weaken rocks and minerals, leading to their eventual breakdown and decomposition.
Two properties of minerals that depend on chemical bonds are hardness, which is determined by the strength of the bonds holding the mineral's atoms together, and cleavage, which is the way a mineral breaks along planes of weakness in its atomic structure.

Halite and gypsum are two examples of evaporite minerals.
Two examples of index minerals are kyanite and staurolite. These minerals are used by geologists to determine the metamorphic grade of a rock based on their presence and abundance.
Well, they are all important but two examples would be calcium and magnesium.
what are two physical properties about minerals
Two examples are quartz and mica. Minerals are also classified as metallic or non-metallic.
Vanadinite and molybdenite are two minerals that are categorized in the hexagonal crystal system.
Minerals break in three main ways: cleavage, fracture, and splintery fracture. Cleavage occurs when minerals break along flat planes defined by their crystal structure. Fracture happens when minerals break irregularly without any specific pattern. Splintery fracture is a type of fracture where the broken piece has sharp edges or splinters.
Halite and Calcite. Halite has what is known as cubiccleavage, where there is cleavage in three directions at 90 degree angles. Calcite has what is known as rhombohedral cleavage, where there is cleavage in three directions but at 120 and 60 degree angles.
Cleavage is a minerals ability to break into even pieces useful for identification. Cleavage in two directions equals Feldspar for example.
Minerals can be found everywhere, you may not even realize how close we come to facing minerals every day. your makeup contains minerals, batteries have the mineral nickel. your pencil contains graphite and clay, two other examples of minerals. Believe it or not your toothpaste contains florite, another common mineral.
