Read the following passage and select the sentence that best supports the following:
Most trenches in the world are located at the perimeter of the Pacific Ocean.

Deep-sea trenches are long, v-shaped, steep-sided valleys on the ocean floor. Their formation is due to plate tectonic activity.  When the leading edge of an oceanic plate meets the leading edge of a continental plate, the crust interacts. Oceanic crust is denser than continental crust, causing the oceanic crust to bend downward. This movement creates a deep v-shape, which becomes a trench. Deep-sea trenches are found between 24,000 to 36,000 feet under water. The deepest known trench is the Mariana Trench in the western portion of the North Pacific Ocean. Its depth is 36,200 feet.

Label each of the compositional and structural layers of Earth.

Which statement best describes Earth's core?

The entire core is solid.

The outer core is liquid, and the inner core is solid.

The outer core is solid, and the inner core is liquid.

The outer core is partly molten, and the inner core is fully molten.

Which minerals make up most of the lithosphere?

magnesium oxides

iron oxides

alumino-silicates

nickel silicates

Convection occurs in the mesosphere layer of Earth.

True

False

Which statement best explains why Earth's lithosphere is broken into tectonic plates?

The brittle lithosphere cracks under pressure from the moving aesthenosphere.

Earthquakes form cracks in the lithosphere that grow larger over time, creating new plates.

Shortly after Earth formed, the lithosphere cooled, causing it to contract and crack.

The lithosphere cracks and deforms under the weight of the continents.

Most tectonic plates contain

only continental crust

no crust

both continental and oceanic crust

only oceanic crust

Categorize the following statements to their respective section.

One of the features is a Rift Valley.
Compressional force is the primary force.
This plate interaction created the San Andreas Fault.
This plate interaction created The Himalayas.
Extensional force is the primary force.
Crust is neither made nor destroyed.

Convergent Boundary
Divergent Boundary
Transform Boundary

What is a byproduct of subduction?

the recycling of oceanic crust

the creation of fault-block mountains

the creation of mid-ocean ridges

the melting of continental crust

A geologist is studying the Fransiscan assemblage in northern California, a melange of sediments that originally formed in the ocean. How might this unit most likely have formed?

the accretion of rock on crust during a mountain-building event

the grinding of tectonic plates sliding past each other at a fault

the cooling of lava as it flows through a spreading center

the breaking of rock into rising blocks as plates move apart at a fault

Much of the evidence of early supercontinents was destroyed as the continents collided and were broken apart or is buried under hundreds of kilometers of rock.

True

False

Which of the following most completely defines volcano?

a vent or hole in the Earth's surface through which melted rock or ash erupt

a partly molten region of Earth's mantle where subducting rock is melted

a ridge system between two diverging plates through which magma escapes

a cone-shaped structure on land where pyroclastic material is ejected

List the four main lava types in order of increasing silica content.

ultramafic
mafic
andesitic
rhyolitic

A hot spot is a relatively stationary plume of magma that can melt through the Earth's lithosphere.

True

False

Which kind of volcanism is most likely to occur at location A in the following map?

Location A is a hot spot in the oceanic crust, so it is likely to erupt lava with a high silica content, resulting in explosive volcanism.

Location A is mid-ocean ridge at a divergent boundary, so it is likely to erupt lava with a low silica content, resulting in relatively quiet volcanism.

Location A is a hot spot in the oceanic crust, so it is likely to erupt lava with a low silica content, resulting in relatively quiet volcanism.

Location A is mid-ocean ridge at a divergent boundary, so it is likely to erupt lava with a high silica content, resulting in explosive volcanism.

Match your volcano type with the correct description.

Draggable item		Corresponding Item
Calderas		large, gently sloped volcanoes that result from the eruption of basaltic lava
Shield Volcanoes		large, steeply sided cones that form from alternating layers of pyroclastic material and lava flows.
Composite Volcanoes (Stratovolcanoes)		small, cone-shaped volcanoes that result from pyroclastic material that falls close to the volcanic vent.
Cinder Cone Volcanoes		Large, collapsed craters over a volcano's empty magma chamber and are formed after extremely explosive eruptions.
