sedimentary
migmatite
igneous
metamorphic
3. Synclines and anticlines are caused by...
deformation of the crust by shearing.
deformation of the crust by compression.
deformation of the crust by tension
4. Mountain ranges along subduction zones are formed, in part, by __ in the crust.
stretching
compression
elongation
extension
5. What happens at divergent plate boundaries?
magma rises to the surface as lava
the plates of Earth's crust move apart
islands can develop
new crust is created
6. What type of fault exists in a rift valley / horst and graben environment?
normal
lateral
transform
reverse
7. What causes earthquakes or tremors of Earth's surface measurable with a seismograph? Select all the correct answers that apply.
volcanoes
mass erosion
shock waves produced by sudden crustal movement along a fault
convection currents in the asthenosphere that push or pull the crustal plates.
8. This geologic structure revealed by the roadcut is a(n):
anticline.
basin.
dome.
syncline.
9. What is the probable mechanism or energy source that causes plate motion?
Catastrophes (severe weather events, volcanic eruptions, earthquakes, etc.)
Convection in the asthenosphere
Density different between the core and crust
Earth's gravitational field
10. What are the three rock type classifications?
silicates, minerals, and crystals
oceanic, continental, and inner core
igneous, sedimentary, and metamorphic
color, hardness, and luster
11. Which is NOT an example of how tectonic plates move?
Transverse (transform or lateral)
Mohorovicic (Moho) discontinuity
Divergence
Convergence
12. During topographic reversals, a synclinal mountain is caused by...
a massive earthquake with compressional force.
the mass erosion of an anticline.
the mass erosion of an anticlinal valley.
the Earth achieving base level then being rejuvenated by a tectonic process.
13. at plate boundaries where oceanic crust converges with continental crust.
Volcanic chains can develop
Deep ocean trenches develop in the subduction zone
Mountain ranges can form
Earthquakes can occur
The oceanic crust subsides because it is more dense than continental crust
14. Horsts and grabens are created by...
deformation of the crust by compression.
deformation of the crust by tension.
deformation of the crust by shearing.
