Plate Boundary Scenario

The Nazca and the South American Plate boundaries is an example of two plates converging. The denser oceanic Plate(Nazca) moves under the continental plate (South America Plate). what features are likely found here

• Rift Valleys

• Volcanoes

• Folded Mountains

• Ocean Basins

The large plates move across the surface of the Earth by what process?

• Convection

• Radiation

• Condensation

• Conduction

The Indian Plate converges with the Eurasian Plate. When two continental plates converge what crustal features is expected to form?

• Rift Valley

• Volcanoes

• Folded Mountains

• Ocean Basin

During sea-floor spreading. How do the ocean crusts move?

• converging

• diverging

• sliding

• no movement

The San Andres Fault in California is known as an active earthquake area. What type of boundary is it?

• converging

• diverging

• transform

• sea floor spreading

When two oceanic plate boundaries meet, what crustal feature forms?

• Plate Tectonics

• Sea Floor Spreading

• Folded Mountains

• Volcanic Island Arc

When two plates of different densities collide, the denser plate moves below the other plate, the rising magma that can result from this type of plate movement may produce

• fossil layers

• volcanic islands

• deep-sea sediment

• seafloor spreading

What geologic process caused the Himalaya Mountain Range to form?

• An earthquake in a subduction zone

• A tectonic plate moving over a hot spot

• Two continental plates converging

• movement at a transform boundary

Evidence that supports the plate tectonics theory includes all of the following EXCEPT:

• New crust is being formed along mid-ocean ridges.

• Volcanoes occur in the middle of tectonic plates.

• Earthquakes occur most frequently along plate boundaries.

• The continents appear to fit together like the pieces of a puzzle.

Folded mountains are associated with which type of plate boundary?

• Convergent

• Divergent

• Subduction Zone

• Transform
