Rock Cycle and Continental Drift

Which statement about the formation of a rock is best supported by the rock cycle?

• Magma must be weathered before it can change to metamorphic rock.

• Sediment must be compacted and cemented before it can change to sedimentary rock.

• Sedimentary rock must melt before it can change to metamorphic rock.

• Metamorphic rock must melt before it can change to sedimentary rock.

One kind of evidence that supports Wegener’s hypothesis is that _______________.

• The same magnetic directions exist on different continents.

• Major rivers on different continents match.

• Land bridges still exist that connect major continents.

• Fossils of the same organism have been found on different continents.

What type of rock is formed by the compaction & cementation of layers of sediment (rock fragments, organic remains, chemical deposits)?

• Igneous rock

• Sedimentary rock

• Metamorphic rock

• Volcanic rock

Why was Wegner's theory of continental drift rejected?

• Wegner's theory was too complex

• There was no evidence to support Wegner's theory

• Scientists did not believe in Wegner's credibility

• He can not prove the movement of the plates
