3
Why do most of the volcanoes on Earth exist along the "Ring of Fire"?
Earth's layers are hotter in that area.

4
What type of convergent boundary can a tsunami ocurr?

5
What event do you predict will occur at the boundary shown?
a mountain range formation
an earthquake
trench formation
volcanic island formation
6
How does the divergent movement of 2 oceanic plates affect the ocean?
Ocean basin increases due to sea floor spreading.
Ocean basin decreases due to sea floor spreading
Ocean basin does not change.
The height of the ocean basin increases.
7
Continental mountain ranges are usually associated with -
