Mineral Properties

What is the definition of a mineral according to the NGSS curriculum?

• A man-made, organic liquid with an indefinite chemical composition and an amorphous structure.

• A naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure.

• A man-made, inorganic solid with a definite chemical composition and a crystalline structure.

• A naturally occurring, inorganic gas with a definite chemical composition and a crystalline structure.

What are the five characteristics that define a mineral?

• synthetic, biological, plasma, changing chemical composition, and chaotic internal structure

• man-made, organic, liquid, variable chemical composition, and disordered internal structure

• artificial, living, gas, unknown chemical composition, and random internal structure

• naturally occurring, inorganic, solid, definite chemical composition, and ordered internal structure

How do minerals form?

• Minerals form through crystallization from magma, precipitation from water, and biological processes.

• Minerals form through nuclear fusion

• Minerals form through evaporation from air

• Minerals form through combustion of organic matter

What is the difference between a mineral and a rock?

• Minerals are formed by biological processes, while rocks are formed by geological processes.

• Minerals are only found on the surface of the Earth, while rocks are found in the Earth's mantle.

• Minerals are always solid, while rocks can be solid, liquid, or gas.

• Minerals have a specific chemical composition and crystalline structure, while rocks are aggregates of one or more minerals.

What are the physical properties used to identify minerals?

• Color, luster, hardness, cleavage, fracture, specific gravity, and streak

• Taste, smell, sound

• Magnetism, flexibility, transparency

• Weight, volume, texture

What is the Mohs scale and how is it used to identify minerals?

• The Mohs scale is used to identify minerals by testing their reaction to acid

• The Mohs scale is used to identify minerals by measuring their weight in relation to a standard weight set

• The Mohs scale is used to identify minerals by testing their scratch resistance against the 10 minerals on the scale, ranging from talc (softest) to diamond (hardest).

• The Mohs scale is used to identify minerals by measuring their electrical conductivity

Explain the difference between cleavage and fracture in minerals.

• Cleavage is the way a mineral breaks with irregular surfaces, while fracture is the way a mineral breaks along flat surfaces.

• Cleavage is the way a mineral breaks into small pieces, while fracture is the way a mineral breaks into large pieces.

• Cleavage is the way a mineral breaks along flat surfaces, while fracture is the way a mineral breaks with irregular surfaces.

• Cleavage is the way a mineral breaks with smooth edges, while fracture is the way a mineral breaks with jagged edges.

How do minerals contribute to the economy and society?

• Minerals contribute to the economy and society by causing environmental degradation and pollution

• Minerals contribute to the economy and society by increasing unemployment and poverty

• Minerals contribute to the economy and society by decreasing the standard of living and quality of life

• Minerals contribute to the economy and society by providing raw materials for industries, creating job opportunities, and generating revenue through exports.
