Front

What property is tested when performing a scratch test on a mineral?

Back

Hardness is the property being tested.

Front

How are rocks classified?

Back

Rocks are classified as igneous, metamorphic, or sedimentary according to how they formed.

Front

What type of rock forms from extreme heat and pressure applied to sedimentary rock?

Back

Metamorphic rock forms from extreme heat and pressure applied to sedimentary rock.

Front

What is an igneous rock?

Back

Igneous rock is formed from the cooling and solidification of magma or lava.

Front

What is a sedimentary rock?

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

Front

What is a metamorphic rock?

Back

Metamorphic rock is formed from existing rocks that are changed by heat, pressure, or chemically.

Front

What is Moh's Scale of Mineral Hardness?

Back

Moh's Scale is a scale that ranks minerals based on their ability to scratch one another.

Front

What is the definition of mineral?

Back

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