Unit 2-7.10AB, 7.11AB

Which of these statements describes how the limestone layers were deposited?

• They were deposited in the ocean and moved inland during a flood.

• They were deposited at the beginning of an ice age when the sea level dropped.

• They were deposited over millions of years when the area was covered by an ocean.

• They were deposited rapidly when ocean water flooded the area after a meteorite impact.

Which of these explanations BEST describes the changes happening along the Mid-Atlantic Ridge?

• The South American and African plates are sliding past each other, making a transform boundary.

• The South American and African plates are colliding into each other, forming mountains along the ridge.

• The South American and African plates are spreading apart, allowing magma to rise and harden into new sea floor.

• The South American and African plates are spreading apart, causing sections of the sea floor to fall into the ridge and melt.

Which explanation for the age of the ocean crust is supported by the data?

• Older ocean crust is being melted back into the mantle where the plates move apart.

• There are ripples on the ocean crust where the continental crust moved over the top of it.

• Ocean crust is older than continental crust so it shows that the continents are younger.

• New ocean crust is being formed at underwater locations where older crust moves away as plates move apart.

Which statement explains how plate tectonics causes ocean basin formation?

• Ocean basins form when one plate moves over another plate.

• After an earthquake, the sea floor spreads and ocean basins are formed.

• As continental plates drift apart, an oceanic basin forms between them.

• Up-welling magma at convergent boundaries spreads out to create an oceanic basin.

This image shows the Hawaiian Islands. Which location is typical of the appearance of super volcanoes?

• at hotspots

• along mid-ocean ridges

• where plates slide past each other

• where plates push toward each other

How do hotspots explain the formation of the Hawaiian Islands?

• Plates slide away from each other, allowing magma to rise up into the crust.

• Plates slide toward each other, pushing up on one another, and resulting in the various islands.

• Magma erupts at various points as plates slide by each other, resulting in the various islands.

• Magma in the mantle rises into the crust, forming a hotspot, and breaks through the crust, forming a volcano.
