The oceanic crust is primarily composed of...

• Mafic Rocks

• Felsic Rocks

• Granite

• Sedimentary Rocks

Which geologic feature is a submarine mountain range commonly found towards the center of ocean basins?

• Abyssal Plain

• Oceanic Trench

• Mid-Ocean Ridge

• Continental Shelf

How did scientists map the seafloor?

• Used SONAR to calculate depth measurements

• Used submarines to explore the seafloor

• Used depth gauges to estimate sea level

• Used geologic mapping to estimate sea level

Why was the discovery of Seafloor Spreading important to the Theory of Plate Tectonics?

• It provided a mechanism to explain how the continents could have moved

• It provided additional evidence to support the Continental Drift hypothesis

• It used SONAR to prove the existence of a mid-ocean ridge

• It provided information to help scientists calculate how fast the continents are moving apart
