What is a mineral?
It is solid and has never
been alive. It has these
three properties:
•hardness
•shape
•color
Row 1, Col 1
What is a rock?
It is made of minerals.
1,2
What is igneous rock?
Rock that was once melted
but has cooled and hardened.
1,3
What is a fossil?
Something that has lasted
from a living thing that died
long ago.
1,4
What is diamond?
The hardest mineral.
2,1
What is the crust?
The thin outer layer of Earth.
It is the part we have seen.
2,2
What is sedimentary rock?
Rock that forms from material
that has settled into layers. The
layers are squeezed together
until they harden into rock.
2,3
What is a mold?
The shape of a plant or animal
left in sediments when the rock
formed.
2,4
What is graphite?
It is dark and dull. The
“lead” in a pencil is made
of this mineral.
3,1
What is the mantle?
The middle layer of Earth.
The crust sits on it.
3,2
What is metamorphic rock?
Igneous, sedimentary, or other
metamorphic rock that has been
changed by heat and pressure.

3,3
What is a dinosaur?
An animal who became extinct
long before there were any
scientists to study them.
3,4
What is quartz?
It is a common mineral.
It is almost as hard as
diamond.
4,1
What is the core?
The center of the Earth.
It is made of very hot iron.
4,2
What is the rock cycle?
The process of changing one
rock into other types.
4,3
Who are scientists?
People who studied the fossil
bones of dinosaurs to find out
about them.
4,4
What is chalk?
This mineral is so soft that
you can write with it.
5,1
What are igneous, sedimentary, and metamorphic?
The three types of rock.
5,2
What are wind and water?
These two things can break up
igneous rocks to form
sedimentary rocks.
5,3
What is a cast?
It forms when mud or minerals
fill a mold. It has the exact
shape of the animal that made
the mold.
