The Mariana islands are volcanic islands that form an arc. The island arc is located in the North Pacific Ocean. These islands were formed by converging tectonic plates.
Which process had to occur in order for these islands to be formed?
melting of oceanic crust at mid-ocean ridge
melting of oceanic crust at subduction zones
production and deposition of magma from hot spots
production and deposition of magma from rift valleys
Oceanic crust is composed mainly of basalt. Continental crust is composed mainly of granite. Why does oceanic crust generally tend to subduct under continental crust when plates collide?
The oceanic crust is thicker than the continental crust.
The continental crust is thicker than oceanic crust.
The oceanic crust is denser than the continental crust.
The continental crust is denser than the oceanic crust.
Seafloor spreading occurs at divergent boundaries. Which statement BEST identifies the geologic process taking place at the point where seafloor spreading occurs?
a trench is forming
new crust is forming
oceanic crust is subducting
a continental plate is subducting
On the ocean floor, there are long mountain ranges called mid-ocean ridges. Which description explains how these geological structures were formed?
a transform boundary where one oceanic plate slides past another oceanic plate
a divergent boundary where two oceanic plates move apart from one another
a convergent boundary where an oceanic plate sinks beneath a continental plate
a convergent boundary where an oceanic plate sinks beneath another oceanic plate
Convection currents in the mantle are a driving force of tectonic movement. At which location do the convection currents cause the plates to diverge?
strike-slip fault
subduction zone
mid-ocean ridges
folded mountains
Along the west coast of South America, volcanic mountains are found due to movement along a plate boundary. The diagram illustrates the movement that is taking place.
Which is the MOST likely reason for the formation of the volcanic mountains?
The volcanic arc is sliding from the continental crust into the trench.
A fault line, created by the sinking lithosphere, is filling with water.
Oceanic crust collides with continental crust, heating as it subducts.
As a result of an earthquake, multiple volcanic arcs are appearing.
Scientists are studying a graph showing the time differences between the seismic P-waves and the seismic S-waves as they travel through Earth. Which information can they learn from the graph?
the magnitude of an earthquake
the duration of an earthquake
the epicenter of an earthquake
the intensity of an earthquake

1.Metamorphic Rocks, 2.Sedimentary Rocks, 3.Igneous Rocks
1.Metamorphic Rocks, 3. Sedimentary Rocks, 2. Igneous Rocks
2.Metamorphic Rocks, 1.Sedimentary Rocks, 3.Igneous Rocks
3.Metamorphic Rocks, 1.Sedimentary Rocks, 2. Igneous Rocks
Which feature results when plates of different densities converge and one plate slips under the other?
a fault
a ridge
a trench
a rift zone
Which scale is used to report the intensity of an earthquake?
Saffir-Simpson Scale
Modified Mercalli Scale
Richter Magnitude Scale
Moment Magnitude Scale
The surface of Earth is composed of large tectonic plates that are constantly shifting as they float on top of molten rock. Which process must occur in the mantle to make the plates move?
normal faulting
seafloor spreading
igneous intrusions
convection currents
Which will most likely form when movement along a plate boundary forces a landmass to be pulled apart?
volcanic island arc
continental mountains
continental rift
oceanic trench
Marta was studying a diagram of the rock cycle. She wanted to know what could cause a sedimentary rock to become a metamorphic rock. Which processes must occur in order for a sedimentary rock to change into a metamorphic rock?
compaction and cementation
heating and pressure
melting and cooling
uplift and erosion
Which is true about the way sunlight changes from winter to summer?
Sunlight travels faster in summer.
Sunlight has higher wavelengths in summer.
Sunlight is more intense in summer.
Sunlight has greater frequencies in summer.
The figure shows the path of a planet orbiting the Sun. The three areas shaded in gray have equal areas.
According to Kepler’s second law, which conclusion is supported by the data?
The time intervals from A to B, C to D, and E to F are all equal.
The distance intervals from A to B, C to D, and E to F combine to be equal to one half of a full orbit.
The time interval from A to B is twice the interval from E to F.
The distance intervals from C to D and from E to F combine to be equal to the time interval from A to B.
The Sun and other stars are powered by nuclear fusion. Which of these statements correctly describes one of the processes that occur during nuclear fusion in stars?
Four hydrogen nuclei combine to become a helium nucleus, absorbing energy.
Four hydrogen nuclei combine to become a helium nucleus, releasing energy.
Four helium nuclei combine to become a hydrogen nucleus, releasing energy.
Four helium nuclei combine to become a hydrogen nucleus, absorbing energy.
Some star formations are more prominent in the night sky of California in summer, while other constellations are more prominent in the night sky in winter. Which best explains why this occurs?
change in the barycenter of Earth
stars revolving around Earth
Earth revolving around the sun
Earth’s rotation on its axis
The diagram shows the relationship of the Sun and Earth if Earth’s axis was not tilted.
How would seasons on Earth differ in this alignment compared to the actual alignment?
Current seasons on Earth would not be affected.
The entire planet would experience the same season at all times.
No point on Earth would experience a change in seasons.
Seasons would switch every six months instead of every three months.
The diagram shows the difference in sunlight reaching Earth at Points 1 and 2.
Based on the diagram, what is another difference between Points 1 and 2?
Tides will be higher at Point 2 than at Point 1.
The pull from gravity will be greater at Point 2 than at Point 1.
Each day is slightly longer than 24 hours at Point 1 and slightly shorter at Point 2.
The region at Point 1 is experiencing summer while the region at Point 2 is experiencing winter.
Which type of plate boundary is MOST responsible for the formation of the Himalayan Range?
divergent boundary within an oceanic crust
divergent boundary within a continental crust
convergent boundary between two oceanic crusts
convergent boundary between two continental crusts
