TRUE
FALSE
- 2. Multiple Choice
Folds are planar structures resulting from brittle deformation caused by two sliding plates
TRUE
FALSE
- 3. Multiple Choice
Movement of tectonic plates and formation of volcanoes are endogenic processes.
TRUE
FALSE
- 4. Multiple Choice
Magma: Intrusive
Lava: Extrusive
TRUE
FALSE
- 5. Multiple Choice
Density and Pressure increase as depth increases
TRUE
FALSE
- 6. Multiple Choice
Removal of volatile during metamorphism increases the rate of the rock to transform into metamorphic rock.
TRUE
FALSE
- 7. Multiple Choice
Strain causes the rock to deform
TRUE
FALSE
- 8. Multiple Choice
Plastic deformation, Ductile deformation and Permanent stage are the three stages of deformation
TRUE
FALSE
- 9. Multiple Choice
Shear stress develops when the two dominant force are directed towards each other on the same axis.
TRUE
FALSE
- 10. Multiple Choice
When one plate subducts and melts beneath the other, magma is likely to be formed.
TRUE
FALSE
- 11. Multiple Choice
How are magma's formed?
Magma's are formed under certain circumstances in special location deep in the crust or in the upper mantle.
Magma's are formed through movement of rocks and minerals.
Magma's are formed through heating and cooling of materials on the earth’s surface
Magma's are formed under the earth’s mantle with the help of worms
- 12. Multiple Choice
How does decompression melting occur?
It occurs when the temperature decreases directly proportional to pressure
It occurs when the temperature increases inversely proportional to pressure
It occurs when the temperature is constant but the pressure decreases
It occurs when the temperature is constant but the pressure increases
- 13. Multiple Choice
What are the natural cracks in the rocks produced by brittle deformation?
Dip
Fault
Joints
Wall
- 14. Multiple Choice
Which of the following is NOT a result of tensional stress?
Mid ocean ridges
Cliff
Folds
Decrease in pressure
- 15. Multiple Choice
How does cataclastic metamorphism occur?
Occurs when sedimentary rocks are buried to depths of several kilometers.
Occurs when heat, pressure and directed stress are all simultaneously applied to a pre-existing rock.
Occurs on a fault line, rock is fragmented and foliated and then reforms itself into a solid state by pressure and heat.
Occurs when hot magma or igneous rock heats pre-existing rock therefore changing the crystallization.
- 16. Multiple Choice
Where does burial metamorphism takes place?
Sedimentary Environment
Mid ocean ridge
Subduction zone
Polar regions
- 17. Multiple Choice
What will happen to the rock after re-crystallization process?
Mineral grains partially dissolve
Different crystal structure.
Same chemical formula
Change in size and shape
- 18. Multiple Choice
What happens after magma is formed?
Magma escaped in two forms intrusion and extrusion
Magma escaped in a tube that can be found on the earth’s mantle
Magma escaped in the form of a magma monster
Magma escaped using a door
- 19. Multiple Choice
Which of the following is NOT a cause of metamorphism?
Weather
Heat
Pressure
Hydrothermal Solution
- 20. Multiple Choice
Why is the Earth’s interior hot?
Because of the magma inside the Earth’s mantle
Because of the metamorphism happened beneath the earth's surface
Because of the global warming that happened on the Earth’s atmosphere
Because of the left over heat from its formation and disintegration of radioactive element
- 21. Multiple Choice
How do rocks behave under compressional stress?
Rocks stretches, causing an elongation parallel to the direction of stress
Rock move directly towards each other but not along the same axis
Rocks expand causing it to move in opposite direction
Rocks squeezes parallel to the direction of stress
- 22. Multiple Choice
What layer of the Earth is considered as the thinnest layer and composed mainly of silicon and aluminum?
Crust
Inner Core
Mantle
Outer Core
- 23. Multiple Choice
How does inner core differ from outer core?
Inner core is composed of liquid metal while outer core is composed of solid iron.
Inner core is composed of solid iron while outer core is composed of melted metal.
Inner core is composed molten rocks while outer core is composed of radioactive decay.
Inner core is composed of silicate mineral while outer core is composed of carbonate mineral.
- 24. Multiple Choice
Which of the following is TRUE about shear stress?
The two dominant forces are directed away from each other but not along the same axis
The dominant force is directed away from each other
The dominant force is directed towards each other but not along the same axis
The dominant force is directed towards each other
- 25. Multiple Choice
It occurs when an extraterrestrial body, such a meteorite or comet impacts with the Earth.
Contact metamorphism
Regional metamorphism
Cataclastic matamorphism
Shock metamorphism
