Unit 3 Bellringer Quiz Review

Which statement describes the geologic processes taking place at a subduction zone?

• A more dense continental plate slides under a less dense oceanic plate destroying some crust.

• A more dense oceanic plate slides under a less dense continental plate destroying some crust.

• A less dense continental plate slides on top of a more dense oceanic plate creating some new crust.

• A less dense oceanic plate slides on top of a more dense continental plate creating some new crust.

A student writes down some possible properties of different layers of Earth.

Which layer(s) is (are) matched with the correct properties?

• continental crust only

• asthenosphere and lithosphere

• asthenosphere only

• continental crust and oceanic crust

Students develop a simple model to illustrate how the movement of the mantle can predict the movement of plates above the mantle. This same phenomenon that influences plate movement can also influence fault formation. They demonstrated this process by using an aquarium, two foam blocks, water, and a heat source. Which description correctly matches a part of the model with what it represents on Earth?

• The heat source represents the energy from Earth’s interior.

• The water represents the material Earth’s crust is made of.

• The large aquarium represents the structure of Earth’s plates.

• The foam blocks represent the location of Earth’s faults.

Which statement best explains what causes the lithospheric plates to move?

• currents in the Earth's magnetic field

• slow flowing liquid in the Earth's outer core

• convection currents in the lower part of the Earth's crust

• convection currents in the upper part of the Earth's mantle

The Mesosaurus was a fresh water reptile that existed on Earth about 250 million years ago. Fossils of the reptile can be found today in some rock layers in both Africa and South America as shown on the map below in locations X and Y.

• The Mesosaurus swam across the ocean due to its migration.

• The continents were once joined together as a single land mass.

• The ocean between the two continents was once frozen, and the Mesosaurus traveled across the ice.

• During a sea level rise and floods fossil remains of the Mesosaurus were carried across the oceans between the two continents.

Which statement is true when comparing the densities of the oceanic crust, the continental crust, and the mantle?

• The continental and oceanic crusts are less dense than the mantle, and the oceanic crust is more dense than the continental crust.

• The continental and oceanic crusts are less dense than the mantle, and the continental crust is more dense than the oceanic crust.

• The continental and oceanic crusts are more dense than the mantle, and the continental crust is more dense than the oceanic crust.

• The continental and oceanic crusts are more dense than the mantle, and the oceanic crust is more dense than the continental crust.

A student makes a model to show two continental plates at a convergent boundary by first breaking a clay block into two pieces. He then pushes the two pieces against one another with constant force, as shown in stages 1 and 2. The student concludes that mountains are formed when two continental plates collide at a convergent boundary. Which statement best supports the student’s conclusion?

• Both halves of the block are equal in dimensions.

• The fault line in stage 1 is vertical, and this is descriptive of all continental boundaries.

• Both stages 1 and 2 have the same densities, and one plate cannot sink under the other.

• The texture of the block resembles continental crust.
