Front

What is crystallization temperature?

Back

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

Front

What does refining mean in the context of minerals?

Back

Refining is the process of extracting a mineral from an ore, which involves separating the valuable components from the waste material.

Front

What is deep mining?

Back

Deep mining is a method of extracting minerals from deep underground, often involving the construction of vertical shafts and tunnels.

Front

What is strip mining?

Back

Strip mining is a surface mining technique where layers of soil and rock are removed to expose and extract minerals close to the surface.

Front

What is open pit mining?

Back

Open pit mining is a surface mining method where a large excavation is made in the ground to extract minerals, typically used for minerals that are located near the surface.

Front

What is prospecting?

Back

Prospecting is the process of searching for mineral deposits, often involving geological surveys and sampling.

Front

What is the difference between ore and mineral?

Back

An ore is a naturally occurring solid material from which a metal or valuable mineral can be extracted profitably, while a mineral is a naturally occurring inorganic substance with a definite chemical composition.

Front

What is the role 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 significance of mineral crystallization in geology?

Back

Mineral crystallization is significant because it helps to form the structure of rocks and can indicate the conditions under which the rock was formed.

Front

What is the process of extracting a mineral from an ore called?

Back

The process of extracting a mineral from an ore is called refining.
