Marion
Alachua
Pinellas
What has caused the mountain range to form?
the collision of tectonic plates
the eruption of a volcano
the deposition of sediments
the abrasion of a glacier
Cracks in rocks widen as water in them freezes and thaws. How does this affect the surface of the Earth?
It exposes rocks to increased rates of erosion and weathering.
It changes the chemical composition of the rocks.
It reduces the rates of soil formation.
It limits the exposure of rocks to acid precipitation.
Which will most likely form when movement along a plate boundary forces a landmass to be pulled apart?
oceanic trench
continental mountains
volcanic island arc
continental rift
Near which geologic structure are the youngest rocks on Earth found?
active volcano
normal fault
The Mid-Atlantic Ridge is a divergent fault on the floor of the Atlantic Ocean. The ridge itself forms a mountain chain that runs the length of the ocean floor from north to south. Which best describes the location of the youngest rock on the floor of the Atlantic Ocean?
close to the top of the mountains on both sides of the Mid-Atlantic Ridge
close to the west side of the Mid-Atlantic Ridge
close to the east side of the Mid-Atlantic Ridge
close to the base of the mountains on both sides of the Mid-Atlantic Ridge
Oceanic crust is denser than continental crust. So when the two meet, oceanic crust subducts under continental crust. This fact best supports which claim?
The hardest rocks on Earth are in the oceanic crust.
The hardest rocks on Earth are in the continental crust.
The oldest rocks on Earth are in the oceanic crust.
The oldest rocks on Earth are in the continental crust.
What type of rocks are associated with lava flows?
sedimentary
hard
igneous
metamorphic
Which of the following best explains why Earth is tectonically active?
Earth’s solid surface layer rotates more rapidly than the layers beneath it.
Earth’s solid surface layer sits on a moving, semiliquid layer.
Areas of Earth’s solid surface layer are under great pressure from ocean water.
Areas of Earth’s solid surface layer are thicker and so heavier than other areas.
The oceanic crust is denser than the continental crust.
false
true
Which of the following changes would end Earth’s tectonic activity?
Earth’s crust becomes a cooler solid.
Earth’s mantle becomes a warmer semiliquid.
Earth’s mantle becomes cooler and solid.
Earth’s outer core becomes warmer.
Which analogy best illustrates why Earth’s plates move?
A tree root grows into a ledge and breaks off a piece of rock.
Burning diesel fuel forces a piston downward, turning the crankshaft.
The ice on a frozen pond cracks when the water beneath it moves.

Which transition is most responsible for gaps in the fossil record?
metamorphic rock to igneous rock
igneous rock to metamorphic rock
metamorphic rock to sedimentary rock
sedimentary rock to metamorphic rock
Which of these is evidence for the theory of plate tectonics?
the shifting of biomes as climates change
the presence of volcanoes around the Pacific rim
the melting of the polar ice caps
the prevalence of granite on all the continents
Magma wells up and forms a ridge down the middle of the Atlantic Ocean, creating new seafloor that slowly spreads out east and west of the ridge. This is evidence for which of the following theories?
Earthquakes result from periodic disturbances along fault lines.
Convection currents in the mantle are the cause of volcanic activity.
Earth’s crust is made up of rocky plates that move over time.
Magma cooling at the surface of Earth forms a type of igneous rock.
Half of a volcanic rock formation can be seen at Pinnacles National Park in California, on one side of the San Andreas Fault. The other half is 195 miles southeast of the park on the other side of the same fault line. This is evidence for which of the following theories?
that earthquakes are the result of volcanic activity
that Earth’s crust is made of rocky plates that shift over time
that Earth’s current landforms were created when Earth’s surface cooled
that rock formations may move hundreds of miles in an earthquake
About 75% of the world’s active volcanoes are the result of tectonic activity around which plate?
Pacific Plate
Mid-Atlantic Ridge
North American Plate
Which of these provides the best evidence that Earth’s crust is divided into tectonic plates?

Which of these is the best evidence that Earth’s continental landmasses drifted apart over time?
the fossil record along the edges of continents
the rocky coastlines at the edges of continents
the distribution of biomes on all the continents
the prevalence of granite on all the continents
