• sedimentary
• igneous
• compacted
• weathered

Heat and ​ (a)   cause physical and / or chemical changes. These changes alter the composition and / or texture of existing rock to form new ​ (b)   rock. Pressure can cause ​ (c)   changes. Pressure can also cause changes to the texture of a rock.

• sedimentary
• water
• physical
• metamorphic
• pressure
• chemical

If rock is exposed to enough ​ (a)   , it can melt completely into a ​ (b)   . Melting turns rock into ​ (c)   rock (magma / lava).

• pressure
• solid
• igneous
• molten
• heat
• liquid
