Observe this diagram of a plate boundary. One statement BEST describes what is happening. It is that

• the oceanic crust is melting.

• the denser ceanic crust is subducting under the less dense oceanic crust

• volcanic islands are forming.

• the tectonic plates are moving away from each other.

What geological forces might be responsible for this range of mountains?

• diverging tectonic plates
• erosion of the land by the ocean
• converging tectonic plates
• deposition of sediments by the ocean

The image shows the Pacific Ring of Fire, a region of high tectonic activity. What evidence supports the theory that the tectonic activity of the region is due to the subduction of tectonic plates?

• The region is bound by many oceanic trenches.
• North America seems to be colliding with Asia at the north of the ring.
• The Asia-Pacific region is dotted by many small and large islands
• The landmasses look like they would fit together like the pieces of a jigsaw puzzle.
