1/17 Mineral Check Up (Open Notes)

What is the definition of a mineral?

• A substance that contains only one type of atom.

• The color of the powder left behind when a mineral is scraped across a surface.

• A substance that forms in nature, is a solid, has a definite chemical makeup, and has a crystal structure.

• The way in which light reflects from its surface (metallic or non-metallic).

What does the term "streak" refer to in the context of minerals?

• The tendency of a mineral to break along flat surfaces.

• The color of the powder left behind when a mineral is scraped across a surface.

• A solid in which the atoms are arranged in an orderly, repeating 3D pattern.

• The way in which light reflects from its surface (metallic or non-metallic).

What is meant by "cleavage" in the context of minerals?

• The color of the powder left behind when a mineral is scraped across a surface.

• A solid in which the atoms are arranged in an orderly, repeating 3D pattern.

• The tendency of a mineral to break along flat surfaces.

• A substance that contains only one type of atom.

What does "luster" refer to when discussing minerals?

• The color of the powder left behind when a mineral is scraped across a surface.

• The tendency of a mineral to break along flat surfaces.

• A solid in which the atoms are arranged in an orderly, repeating 3D pattern.

• The way in which light reflects from its surface (metallic or non-metallic).

What does the term "Fracture" refer to in geology?

• The process by which rocks are formed

• The tendency of a mineral to break into irregular pieces

• The layering of sedimentary rocks

• The measurement of earthquake intensity

What does "Hardness" measure in terms of a mineral's properties?

• The mineral's ability to float in water

• The mineral's resistance to being scratched

• The mineral's magnetic properties

• The mineral's reaction to acid

What is "Magma"?

• Solid rock found on the Earth's surface

• Molten rock inside the Earth

• The outer layer of the Earth's atmosphere

• A type of mineral deposit

How is "Lava" different from "Magma"?

• Lava is found only in the Earth's core, while magma is on the surface

• Lava is a type of sedimentary rock, while magma is igneous

• Lava is molten rock that has reached the Earth's surface

• Lava is a solid rock, while magma is molten

Which is NOT a property used for identifying minerals?

• taste

• streak

• hardness

• color

The size of a mineral's crystals depends on which of the following?

• the mineral's crystal group

• the solution from which the mineral formed

• the smelting process in which the magma formed

• the rate of cooling of the magma or solution from which the mineral formed
