Introduction to ROCKS!

Uses of Rocks: Old and New
• Old • New
Next
Fossils
• Mt. Charleston • Fossils of animal/plant life that typically lives in oceans found on mountains proves the mtn. was once underwater.

3 Types of Rocks
Igneous Sedimentary Metamorphic
Next
Rock Cycle
• A rock can change into any rock.– ex. A metamorphic rock can become a
sedimentary rock, igneous rock, or even back into another metamorphic rock.
Next
Rock Cycle
Next
Igneous Rock
• Formed by: Melting and Cooling
• Associated with magma, and volcanoes
Next
Igneous Rocks
• Intrusive: cooled inside the Earth.
• Typically has larger crystals (cools slowly).
• Extrusive: cooled on Earth’s exterior.
• Typically has smaller crystals (cools quickly).

Sedimentary Rock
• Formed by: – weathering (broken
down rocks from weathering)
– eroding (sediments moving)
– compaction and cementation
Next
Sedimentary Rocks
• Strata: layers; common feature found in sedimentary rocks (but not mandatory)
• Sedimentary Rock Video Clip
Next
Metamorphic Rock
• Formed by: heat and/or pressure

2 Types of Metamorphic Rocks
Foliated• Minerals align like pages in
a book
Nonfoloiated• Minerals have no regular
pattern

Question #1
• Rocks have had many uses in the past, and today. Rocks have been used for…
• A. creating buildings• B.
identifying local history• C. tools• D. all of the above
#1 Nice Try!
• Please try again, there is a better answer!
Try Again
#1 Correct!
• Way to go!– Rocks are used for creating buildings, tools, and
identifying an area’s history. If fossils of water plants and animals are found on top of a mountain, that would tell us that a mountain was actually much lower many years ago, but has since uplifted and the water has moved away leaving behind fossils of the plants and animals that used to live there.

Question #2
• A sedimentary rock can become a(n)…
• A. igneous rock• B. sedimentary rock• C. metamorphic rock• D. all of the above
#2 Nice Try!
• Please try again, there is a better answer!
Try Again
#2 Correct!
• Way to go!– All rocks can become another rock, and/or
actually turn back into the same type of rock!• For example, a sedimentary rock can weather and
break down into sediments. Then those sediments can compact and cement together into another sedimentary rock!
Next Question
Question #3
• The natural process that makes up an igneous rock is…
• A. melting and cooling• B. heat and/or pressure• C.
weathering/erosion and compaction/cementation
• D. weathering and pressure
#3 Nice Try!
• Please try again, there is a better answer!
Try Again
#3 Correct!
• Well done!– The process to become a rock is melting and
cooling.
Next Question
Question #4
• An igneous rock that is formed inside the Earth is…
• A. congruent• B. intrusive• C. foliated• D. extrusive
#4 Nice Try!
• Please try again, there is a better answer!
Try Again
#4 Correct!
• Well done!– Remember, INtrusive igneous rock is formed
INside the Earth
Next Question
Question #5
• Why do extrusive igneous rocks have smaller crystals?
• A. They cool slowly• B. They cool quickly• C.
They form inside the Earth
• D. They are coarse-grained
#5 Nice Try!
• Please try again, there is a better answer!
Try Again
#5 Correct!
• Well done!– Remember, extrusive rocks cool quickly (generally
on the Earth’s surface) and therefor doesn’t give the crystals much time to grow.
Next Question
Question #6
• Fossils are mainly found in what type of rock?
• A. Igneous• B. Sedimentary• C. Metamorphic• D.
Common in all types of rock
#6 Nice Try!
• Please try again, there is a better answer!
Try Again
#6 Correct!
• Well done!– Fossils can be found in metamorphic (although
becoming distorted), they are most commonly found in sedimentary rock
Next Question
Question #7
• Weathering, erosion, deposition, compaction and cementation are all processes in forming what type of rock?
• A. Igneous• B. Sedimentary• C. Metamorphic• D. All of the above
#7 Nice Try!
• Please try again, there is a better answer!
Try Again
#7 Correct!
• Well done!– Sedimentary rocks are formed by weathering
(breaking down of rock becoming sediments), erosion (movement of sediments), deposition (settling of sediments),
Next Question
Question #8
• What are the layers in sedimentary rock called?
• A. nonfoliated• B. intrusive• C. magma• D. strata
#8 Nice Try!
• Please try again, there is a better answer!
Try Again
#8 Correct!
• Well done!– Strata is a very common feature, otherwise known
as layering, found on sedimentary rocks.
Next Question
Question #9
• This type of rock is formed by heat and/or pressure.
• A. Igneous• B. Sedimentary• C. Metamorphic• D.
Igneous and Sedimentary
#9 Nice Try!
• Please try again, there is a better answer!
Try Again
#9 Correct!
• Well done!– Metamorphic rocks can be formed by either heat,
pressure, or heat and pressure.
Next Question
Question #10
• What term best describes a metamorphic rock when their minerals align like pages in a book due to pressure?
• A. Nonfoliated• B. Stratification• C. Foliated• D. Fine-grained
#10 Nice Try!
• Please try again, there is a better answer!
Try Again
#10 Correct!
• Well done!– Foliated is the term to describe minerals that align
next to each other (looks like layers/pages in a book). Nonfoliated is when minerals have no regular pattern.
