Uses of Rocks: Old and New Next

Next Fossils Mt. Charleston Fossils of animal/plant life that typically lives in oceans found on mountains proves the mtn. was once underwater. Next

3 Types of Rocks Igneous Sedimentary Metamorphic Next

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

Next Igneous Rock Formed by: Melting and Cooling Associated with magma, and volcanoes Next

Igneous Rock Video Clip 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). Igneous Rock Video Clip Next

Next Sedimentary Rock Formed by: weathering (broken down rocks from weathering) eroding (sediments moving) compaction and cementation Next

Next Sedimentary Rocks Strata: layers; common feature found in sedimentary rocks (but not mandatory) Sedimentary Rock Video Clip Next

Next Metamorphic Rock Formed by: heat and/or pressure Metamorphic Rock Video Clip Next

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

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

Next Question #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. Next Question

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

Next Question #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

Next Question #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

Next Question #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

Next Question #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

Next Question #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

Next Question #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

Next Question #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

Next Question #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

Next #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. Next
