- 1. Multiple ChoiceAccording to tectonic plate maps, New York State is presently locatedAt a convergent plate boundaryAbove a mantle hotspotAbove a mid ocean ridgeNear the center of a large plate
- 2. Multiple ChoiceAt which location would you expect to find the deepest earthquakes?Mid Atlantic RidgeSan Andreas FaultHawaiiJapan
- 3. Multiple ChoiceWhat tectonic process often occurs when two continental plates collide?SubductionMountain Building (uplift)island formationseafloor spreading
- 4. Multiple ChoiceWhich statement best supports the theory that all the continents were once a single landmass?Rocks of the ocean ridges are older than those of the adjacent seafloor.Rock and fossil correlation can be made where the continents appear to fit togetherMarine fossils can be found at high elevations above sea level on all continentsGreat thicknesses of shallow water sediments are found at interior locations on some continents
- 5. Multiple ChoiceThe age of oceanic bedrock on either side of a mid-ocean ridge is supporting evidence that at the ridges, tectonic plates areDivergingConvergingLocked in placeBeing subducted
- 6. Multiple ChoiceWhich method of energy transfer is primarily responsible for energy being lost from Earth into space?ConductionConvectionRadiationTransmission
- 7. Multiple ChoiceWhen a continental crustal plate collides with an oceanic crustal plate, the continental crust is forced to move over the oceanic crust. What is the primary reason that the continental crust stays on top of the oceanic crust?Continental crust is less dense.Continental crust deforms less easily.Continental crust melts at higher temperatures.Continental crust contains more mafic minerals.
- 8. Multiple ChoiceWhat happens to the density and temperature of rock within Earth’s interior as depth increases?Density decreases and temperature increasesDensity decreases and temperature decreasesDensity increases and temperature increasesDensity increases and temperature decreases
- 9. Multiple ChoiceWhich observation about the Mid-Atlantic Ridge region provides the best evidence that the seafloor has been spreading for millions of years?The bedrock of the ridge and nearby seafloor is igneous rock.The ridge is the location of irregular volcanic eruptions.Several faults cut across the ridge and nearby seafloor.Seafloor bedrock is younger near the ridge and older farther away.
- 10. Multiple ChoicePlate boundaries are characterized byreversed magnetic orientationunusually rapid radioactive decayfrequent volcanic activitylow P wave and high S wave velocity
- 11. Multiple ChoiceWhat type of plate boundary is located at the San Andreas Fault?ConvergentDivergentTransformSubduction
- 12. Multiple ChoiceWhich temperature is inferred to exist in Earth’s plastic mantle?2000C3000C5000C6000C
- 13. Multiple ChoiceThe large coal fields in Pennsylvania provide evidence that the climate of the northeastern U.S. was much warmer during the Carboniferous Period. This change in climate over time is best explained by theThe movement of tectonic platesEffects of seasonsChanges in the environment caused by humansEvolution of life
- 14. Multiple ChoiceWhich two tectonic plates are separated by a mid-ocean ridge?Indian-Australian and EurasianIndian-Australian and PacificNorth American and South AmericanNorth American and Eurasian
- 15. Multiple ChoiceWhich form of heat flow is responsible for the slow circulation within Earth’s upper mantle (asthenosphere)?ConductionConvectionRadiationRefraction
