What is a mineral?

Back

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

What is the importance of color in mineral identification?

Back

Color can vary due to impurities and is not a reliable sole indicator for identifying minerals.

Front

What does the term 'hardness' refer to in minerals?

Back

Hardness measures a mineral's resistance to scratching, often assessed using the Mohs scale.

Front

What is 'cleavage' in mineralogy?

Back

Cleavage is the tendency of a mineral to break along flat, even surfaces.

Front

What is 'fracture' in the context of minerals?

Back

Fracture refers to the way a mineral breaks when it does not cleave, resulting in uneven surfaces.

Front

What tool is used to determine the streak of a mineral?

Back

A streak plate is used to find the color of a mineral's powder.

Front

What does specific gravity (SG) indicate about a mineral?

Back

Specific gravity is a measure of the density of a mineral compared to the density of water.

Front

Which mineral is known to scratch talc but not calcite?

Back

Gypsum can scratch talc but cannot scratch calcite.

Front

Why is the breaking pattern of a mineral important?

Back

The breaking pattern helps identify the mineral and understand its properties.

Front

What is the Mohs scale?

Back

The Mohs scale is a scale from 1 to 10 used to rank the hardness of minerals.
