3
Earthquakes and volcanic activity occur along the Pacific Ring of Fire shown below. Why?
It is located where the major ocean currents meet
it is located in the center of a tectonic plate
It is located at the boundaries of tectonic plates
It is located where ocean temperature is the highest

13
Scientist found fossils of tropical plants in Greenland. How did they get there?
volcanic eruptions melted ice and exposed soil
Antarctica was closer to the equator at one time
rotation of Earth
Earth's entire surface was covered by tropical forests
