A type of rock that forms when particles from other rocks or the remains of plants and animals are pressed and cemented together

A type of rock that forms from an existing rock that is changed by heat, pressure, or chemical reactions.

A type of rock that forms when melted rock cools and hardens.

The process that converts sediments into solid rock by compaction or cementation.

Rock that contains a metal or economically useful mineral
