Lithospheric Movement Test Review

Which feature would most likely be forming at converging continental tectonic plate boundaries?

• rift valley

• deep trench

• volcanic cone

• folded mountain

Which of the following is the best evidence that Earth’s continents were once in vastly different positions than they are today?

• Penguins are found only in the Southern Hemisphere.

• Fossils of tropical plants are found in Antarctica.

• Volcanoes encircle the Pacific Ocean.

• Major rivers form deltas from continental erosion.

3. A rift valley is evidence of which kind of plate boundary?

• convergent

• divergent

• transform

• uniform

Which of the following is most responsible for the formation of new crust at the edge of a tectonic plate?

• mountain building at a continent-continent convergent boundary

• magma rising up from the mantle at a divergent boundary

• two tectonic plates sliding past one another at a transform boundary

• subduction of one oceanic plate under another at a convergent boundary

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

The diagram below shows the direction of plate movement along the mid-ocean ridge.

Which set of arrows BEST shows the convection currents associated with the formation of a mid-ocean ridge?

• 
• 
• 
• 

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 higher density of the oceanic crust

• the weight of the ocean water on the oceanic crust

• the reduction of friction on the oceanic crust

• the depth of the oceanic crust

Which of the following would MOST likely slow Earth’s tectonic activity?

• Earth’s crust becomes cooler.

• Earth’s mantle becomes warmer.

• Earth’s mantle becomes cooler.

• Earth’s outer core becomes warmer.

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

• volcanic eruption

• meteoroid impact

Mr. Thompson’s class was discussing the topic of tectonic boundaries. He asked the students to identify a landform that was made at a convergent boundary. Which landform should the students identify?

• North American Continent

• Marianas Trench

• Mid-Atlantic Ridge

• Hawaiian Islands
