Any rock that forms from another rock as a result of changes in heat or pressure (or both) is a:

• chemical rock

• igneous rock

• sedimentary rock

• metamorphic rock

This is the continuous process of rock changing from one type to another.

• Igneous rocks

• Sedimentary rocks

• Metamorphic rocks

• Rock Cycle

Limestone is a sedimentary rock. During the rock cycle, limestone is changed into marble, a metamorphic rock. The processes that act on limestone and change it into marble are

• weather and erosion

• heat and pressure

• compacting and cementing

• melting, cooling, and hardening

This is a natural solid that is made of one or more minerals.

• Mineral

• Fossil

• Rock

• Sediment
