Use the diagram of the subduction zone to answer the question that follows. What causes the oceanic crust to be pushed under the continental crust?

• the reduction of friction on the oceanic crust

• the depth of the oceanic crust

• the higher density of the oceanic crust

The diagram shows the motion of tectonic plates.Which term provides the MOST accurate classification of the geologic structure shown?

• transform boundary

• convergent boundary

• divergent boundary

• plate tectonics

Which statement describes an aspect of tectonic plate motion directly caused by density differences among tectonic plates?

• Oceanic plates move outward from the mid-ocean ridge.

• When oceanic and continental plates collide, the ocean plate is subducted.

• Continental plates are thicker and contain older material than oceanic plates.

• The orientation of magnetic particles in oceanic plates changes at regular intervals

Tectonic motion caused tension between plates in Earth’s crust. A sudden release of this energy occurred. Based on this information, which event happened?

• subsidence

• earthquake

• volcano

• hurricane

A volcano found in the center of a tectonic plate tends to be a result of which phenomenon?

• strong earthquake

• activity at a hot spot

• pressure in thick sediments that produces heat

• unusually excessive erosion that wears away bedrock

Earthquakes can be severe along the San Andreas Fault in Southern California, but volcanoes are nonexistent. Which statement BEST explains this pattern?

• The crust is thin and weak at the location of this fault.

• The material along this fault is smooth and fine grained.

• The material in the mantle solidified due to cooling under this fault.

• The crustal plates slide along each other without sub-ducting at this fault
