2. • Students will observe and compare
several different kinds of rocks.
• Students will observe fossil remains and
compare to pictures of original.
• Students will observe via pictures the
effects of weathering, erosion,
temperature and pressure.

5. Click here to learn the
definition of Igneous Rocks

6. Scoria rocks are Igneous rocks which were
formed when lava cooled quickly above ground.
You can see where little pockets of air had been.

8. Basalt is an extrusive
igneous rock that is very
dark in color. It is the
most common type of
rock in the Earth’s crust,
and makes up most of the
ocean floor.

9. Basalt is also an abundant
rock on the Moon.
Olympus Mons is a shield volcano on Mars.
It was formed from basaltic lava flows. It
Is the highest mountain on Mars and is the largest
known volcano in our solar system.

10. Pillow basalts on the South Pacific seafloor.

11. Tuff is rock that is composed of volcanic ash and other
materials that were ejected from a Volcano, fell to Earth,
and then cooled to form rocks.
.

12. Pumice rocks are Igneous rocks which were
formed when lava cooled quickly above ground.
You can see where little pockets of air had been.
This rock is so light, that many pumice rocks will
actually float in water.
Because this rock is so light, it s often used
for decorative landscape stone. Ground to a
powder, it is often used as an abrasive in soaps.

18. Parts of rocks, materials, or animal
or plant material combined to form
rock.
Click here to learn the
definition of Sedimentary Rocks

19. Shale rock is a type of sedimentary rock formed from clay.
They are used to make bricks and other materials that are
fired in a kiln.

20. Sandstone rocks are sedimentary rocks made from
small grains of sand and matrix. They are often used
as building stones.

21. Limestone rocks are sedimentary rocks
that are made from the mineral calcite which
came from the beds of evaporated seas and
lakes and from sea animal shells. This rock is
used in concrete and is an excellent building
stone .

22. Conglomerate rocks are sedimentary
rocks. They are made up of large sediments
like sand and pebbles. The sediment is so large
that pressure alone cannot hold the rock
together, it is also cemented together with
dissolved minerals.

23. Gypsum rocks are sedimentary rocks made up of sulfate
mineral and formed as the result of evaporating sea water
In massive prehistoric basins. It is very soft and is used to
make Plaster of Paris, casts, molds, and wallboards.

24. Coal is made up of layers of plant and vegetable material
that has been compacted, hardened and transformed
by heat and pressure over millions of years.

26. Are these examples of Sedimentary
Rocks?

29. What are Fossils?
Fossils are the remains or impressions
left by plants or animals that lived a
long time ago.

30. Fossil of Trilobite
Click on the fossil to see the Trilobite

31. Fossil of Horn Coral
Click on the fossil to see the Horn Coral

32. Mosasuar Tooth Fossil
Click on the Mosasuar tooth fossil to see a Mosasuar

33. True or False.
Fossils tell us about Earth’s
future.
True False

34. Try Again!
Fossils tell us a story
about the Earth’s past!

35. Great Job!
Fossils don’t tell us about Earth’s future –
They tell us about Earth’s past!

changed to another under the influence of heat or
pressure.

metamorphism of
sandstone.

45. How do rocks change?

46. Weathering
Weathering is the
process
that causes rocks
to crumble, crack, or
break.
