Question 11

Why does oceanic lithosphere almost always sink beneath continental lithosphere at convergent plate boundaries?

Accepted Answer

A)  Oceanic lithosphere moves so slowly that it can only sink. 
B)  Oceanic lithosphere is at the bottom of the ocean, so it can't float high enough to ride over a continent. 
C)  Oceanic lithosphere is almost twice as dense as the underlying mantle. 
D)  Oceanic lithosphere is denser than continental lithosphere. 
E)  Oceanic lithosphere is partly liquid, so it floats on the solid continental lithosphere.

Accepted Answer

They are hotspot volcanoes.A hot plume o

Question 13

Why do many oceanic volcanoes occur as long lines of volcanoes that are active at only one end?

Accepted Answer

A)  The lithosphere moves over a stable hotspot in the mantle. 
B)  The mantle convection cell under the crust carries the magma source from one end of the line of volcanoes to the other. 
C)  The mantle plume that feeds the volcano rotates around the Earth's core, tracing new volcanoes as it does. 
D)  The spreading lithosphere pushes the underlying magma source across the ocean floor. 
E)  The active volcanoes are gradually moving away from the oceanic ridge.
