CH. 15 flashcard

Front

What is crystallization temperature?

Back

Crystallization temperature is the temperature at which a mineral begins to crystallize from a cooling magma. Different minerals crystallize at different temperatures.

Front

What is ore?

Back

Ore is a type of rock that contains sufficient minerals with important elements including metals that can be economically extracted from the rock.

Front

What is the difference between deep mining and strip mining?

Back

Deep mining involves extracting minerals from deep underground, while strip mining involves removing surface layers to access minerals near the surface.

Front

What happens to sediment when stream velocity decreases?

Back

When stream velocity decreases, the sediment being transported undergoes deposition, meaning it settles out of the water and accumulates.

Front

What is gangue?

Back

Gangue is the waste material that surrounds or is mixed with a desired mineral in an ore.

Front

What is the process of ore refining?

Back

Ore refining is the process of separating valuable minerals from the gangue to obtain pure metal or mineral.

Front

What is the significance of viscosity in magma?

Back

Viscosity refers to the thickness or resistance to flow of magma. It affects how easily magma can move and how quickly minerals can crystallize.

Front

What is the role of density in mineral separation?

Back

Density plays a crucial role in mineral separation as minerals with different densities can be separated through processes like gravity separation.

Front

What is mass movement in geology?

Back

Mass movement refers to the downward movement of soil and rock due to gravity, which can occur rapidly or slowly.

Front

What is the difference between erosion and deposition?

Back

Erosion is the process of wearing away and transporting soil and rock, while deposition is the accumulation of sediment in a new location.
