The document summarizes key information about rocks and the rock cycle. It describes three main types of rocks - igneous, sedimentary, and metamorphic rocks. Igneous rocks form from cooling magma, and there are two types: intrusive rocks like granite that cool slowly underground, and extrusive rocks like obsidian that cool rapidly above ground. Sedimentary rocks form from compression of sediments, and examples include sandstone, limestone, and shale. Metamorphic rocks form from changes to existing rocks through heat, pressure, and chemical processes, changing the rock type, and examples include slate, schist, and marble. The rock cycle diagram illustrates how rocks continuously change between these three types through geological

1. LITHOSPHERE

2. Lithosphere
outermost solid
part of the earth
made up of rocks

3. ROCKS

4. Where can we find rocks?
beneath the oceans
EVERYWHERE
highways

5. Why rocks differ from
one another?
air holes
mineral contents
Content remains of the
plants and animals

6. Rocks
are made
up of
minerals

7. Physical Properties
of Rocks

8. Color
most observable characteristics of rocks
Jade
Ruby
Aquamarine

9. Luster
refers to the quality of light that surface
of mineral reflects
Gold Pyrite

10. Streak
refers to the color of a thin layer of
powdered mineral

11. Hardness
refers to a mineral resistance to scratching
Diamond
Gypsum
Talc

12. Cleavage
refers to how minerals break
Quartz
Mica

13. 3 Kinds of Rocks
Igneous Rocks
Sedimentary Rocks
Metamorphic Rocks

14. Igneous Rocks

15. Igneous Rocks
are rocks which came from very, very
hot and melted magma below the
earth’s crust

16. 2 Kinds of Igneous Rocks
Intrusive Igneous Rock
Intrusive Igneous Rock

17. Intrusive Igneous Rocks
rocks that form from magma trapped
below the earth’s surface
have large mineral grains and a coarse
grained texture

18. Granite Basalt

19. Extrusive Igneous Rocks
rocks formed from cooled lava on the
earth’s surface
Have finer texture

20. Obsidian
Pumice

21. Examples
of
Igneous Rocks

22. Granite
formed from magma that cooled
slowly
has a coarse grained texture
may be pink, white-gray, or light to
moderate yellow
its mineral grains are similar in size

23. Example: Granite

24. Basalt
formed from lava that cooled rapidly
has fire grained texture
its mineral grains are so tiny
maybe black or dark green

25. Example: Basalt

26. Obsidian
formed from lava that cooled rapidly
has a texture as smooth as glass
maybe brown or black
it is hard and brittle

27. Example: Obsidian

28. Pumice
formed from lava
Looks like a sponge with many holes
It is light and float on water
Maybe light yellow or gray
Its mineral content glass

29. Example: Pumice

30. Sedimentary Rocks

31. Sedimentary Rocks
formed from sediments

32. Examples
of
Sedimentary
Rocks

33. Sandstone
consist of fine sand cemented together
it is coarse-grained and filled with tiny
holes or spaces

34. Limestone
made up of shells and skeletons of small
sea animals

35. Conglomerate
made from a mixture of round pebbles
and stones
has a course mixture

36. Shale
formed from fine mud clay and silt.
it has a smooth surface and can be slit
into layers

37. Dolomite
similar to limestone
composed mainly of magnesium

38. Metamorphic Rocks

39. Metamorphic Rocks
formed from igneous rocks sedimentary
and even other metamorphic rocks

40. Examples
of
Metamorphic
Rocks

41. Slate
comes from shale
hard and smooth
breaks into flat sheets

42. Schist
made from mudstone

43. Serpentine
a rock that easily crumbles to the weather
it is slippery

44. Quartzite
made from sandstone

45. Gneiss
formed from shale, sandstone, granite
and conglomerate

46. Marble
comes from limestone

47. Rock Cycle

48. Rock Cycle
continuous change from one form to
another as a result of same process
that happen in nature
