The answers would be:
Igneous Rocks - They are made from hot magma.
Sedimentary Rocks - They are made from
weathered pieces of rock.
Metamorphic Rocks - They are rocks, small or large
which reformed due to high temperature.
If you'd like to know more, read on:
Igneous rocks are formed when hot magma is cooled
and then it hardens into a rock. The word igneous
comes from the word, "ignis" which means "of fire.
They can be formed beneath the Earth or on the
surface.
Sedimentary rocks are formed from weathered
pieces of rock. These pieces are called sediments.
They can also be made out of other material. When
these sediments settle, it continues to do so until so
much sediment accumulate and they start to press
down on each other. The sediments then start to go
through compaction and sedimentation which for a
sedimentary rock.
Metamorphic rocks form under heat and pressure.
They are squeezed and shaped and go through
metamorphosis or go through change. A
metamorphic rock can be formed from any other type
of rock as long as it goes through changes due to
intense pressure and/or heat.
