SC.7.E.6.7

Dina knows that most volcanoes form near the boundaries of tectonic plates. She studies one volcano, however, that formed in the middle of a crustal plate. How could this have happened?

a. Some plates give off more heat than others.

b. The heat that formed the volcano came from above the plate.

c. It formed along a hot spot, or a very hot part of the mantle.

d. The volcano formed underground because a mountain was located above it.

SC.7.E.6.7

Jorge is investigating how ocean basins change over time. He knows that mid-ocean ridges are found in ocean basins. Which of the following statements about mid-ocean ridges and ocean basins is most accurate?

a. Ocean basins are most active in places where there are no mid-ocean ridges.

b. The crust at a mid-ocean ridge is younger than the crust in an ocean basin far from a mid-ocean ridge.

c. The pushing together of tectonic plates creates ocean basins and mid-ocean ridges.

d. A volcano is less likely to occur at a mid-ocean ridge than in another part of an ocean basin.
