Open Ended

How did the findings from the Deep Sea Drilling Project contribute to the development of the seafloor spreading hypothesis?

Multiple Choice

Which of the following best explains how the Hawaiian Island-Emperor Seamount chain provides evidence for plate movement?

• The islands are all the same age.

• The chain shows a clear age progression from youngest to oldest islands.

• The islands are randomly distributed.

• The islands are formed by continental drift.

Multiple Select

Which of the following are pieces of evidence provided by Earth's magnetic field that support the theory of continental drift?

• Magnetite grains act like compass needles

• Record magnetic pole positions at formation time

• Provide evidence of continental drift

• Create new oceanic crust

Multiple Choice

How did the Deep Sea Drilling Project contribute to our understanding of plate tectonics?

• It revealed seafloor age patterns through ocean sediment drilling.

• It discovered new continents under the ocean.

• It proved that volcanoes do not affect tectonic plates.

• It found that the ocean floor is older than the continents.

Multiple Choice

Why was the evidence gathered from ocean drilling, volcanic patterns, and magnetic field studies significant for our understanding of Earth?

• It helped confirm the theory of plate tectonics and revolutionized our understanding of Earth's processes.

• It only provided information about ocean life.

• It disproved the existence of tectonic plates.

• It was mainly used for navigation purposes.
