| The Rock Cycle | ||
| #1 | What forces could cause a metamorphic rock to become magma? (For 40 extra points, name how this force can occur inside earth)
|
MELTING
Bonus 40 points: It is caused by plate tectonics or the crashing of plates |
| #2 | What step in the rock cycle creates the sediment from which sedimentary rock is formed? |
Erosion |
| #3 | In the rock cycle, what happens to magma and lava once they cool and harden?
|
Forms Igneous Rock |
| #4 | Must sedimentary rock become metamorphic rock before it can become magma?
For a 40 point bonus: Explain your answer
|
No
Bonus: Sedimentary rock can melt and turn to magma |
| #5 | Describe two pathways through the rock cycle in which igneous rock can become metamorphic rock.
|
1. Erosion - Sedimentary Rock - Heat and Pressure - metamorphic rock 2. Heat and Pressure |
| Igneous Rock | ||
| #1 | Igneous rock that cools very quickly when it forms may have a texture that is: A smooth and shiny with no visible grain or B. Course grained |
A. smooth and shiny with no visible grain |
| #2 | Rocks that forms from the cooling of magma below the surface or lava at the surface is called... |
Igneous Rock |
| #3 | Igneous rock that formed from lava that erupted onto Earth's surface is called... |
extrusive rock |
| #4 | Generally a rock is made up of: A. Only inorganic materials B. a mixture of minerals and other materials C. small crystals |
B. Mixtureof minerals and other materials |
| #5 | Does Lave form an intrusive or extrusive rock? |
extrusive |
| Sedimentary Rock | ||
| #1 | Erosion on a mountain range that was pushed up as a result of two continental plates colliding will lead to the formation of.... |
Sedimentary Rock |
| #2 | The process in which dissolved minerals crystallize and GLUE particles of sediment together is... |
cementation |
| #3 | How can a fossil of a fish be found in a sedimentary rock? |
Fish dies and is buried by sediment on the bottom of a river or lake. |
| #4 | What kind of rock is made from coral? |
Limestone |
| #5 | Describe a pathway through the ro cycle in which magma becomes sedimentary rock
|
Magma cools becomes Igneous Rock,then Erosion, then Sedimentary Rock |
| Metamorphic Rocks | ||
| #1 | Where does metamorphic rock form? |
deep underground |
| #2 | Heat and Pressure deep beneath Earth's sruface can change any rock into.... |
metamorphic rocks |
| #3 | The heat that changes a rock into metamorphic rock comes from: A. the Sun B. Volcanoes C. heat of the mantle |
C. The heat of the mantle |
| #4 | The texture of a metamorphic rock that has grains arranged inparallel layers is described as... |
foliated |
| #5 | What would happen if the mantle of the Earth cooled? |
No more heat to make metamorphic rocks and no more magma to create Igneous rocks. |
| Potpourri | ||
| #1 | What forms the structure called a coral reef? |
Skeletons of coral animals |
| #2 | A series of processes on Earth's surface and in the crust and mantle that slowly changes rocks from one kind to another is called... |
the Rock Cycle |
| #3 | Which of the following is NOT one of the possible stages in the rock cycle? A. volcanic activity B. Erosion C. Smelting D. Melting |
C. Smelting |
| #4 | Why can we find limestone in the middle of the United States? |
Limestone is formed in shallow warm ocean water. One time due to continental drift the United States was covered with ocean water and near the equator. |
| #5 | Why doesn't metamorphic rock rarely forms at Earth's surface? |
You need the heat from the mantle and pressure from plate tectonics deep underground. |
| Final Question | |
What is Mr. T's favorite line from Mr. Lee's (Drake) rock cycle song? |
"Which is soil, small rocks, and whatever man" |
