The Rock Cycle
‘Rocks are neither created or destroyed, but are redistributed and transformed from one rock type to another’
• Rocks are divided into
families based on how they
are formed • Igneous • Sedimentary • Metamorphic
Igneous rocks are formed when magma or lava, which are liquid, cool and
harden to become rocks.
Sedimentary rocks are made of small pieces of rocks that settle in lakes and seas. The small pieces of rock settle to the bottom in layers and after a long period of time, harden into new rocks.
Metamorphic rocks are rocks
that have been changed by heat, by pressure, or by both.
