What technology was developed that gave us an idea of how the ocean floor is contoured (shaped)?

• Sonar

• Radar

• GPS

• Satellite Imaging

Who was the first person to use this technology for geological purposes?

• James Hutton

• Charles Lyell

• Alfred Wegener

• Harry Hess

What did he theorize was happening at the Great Global Rift (mid-ocean ridges) and at deep ocean trenches?

• Formation of new oceanic crust at mid-ocean ridges and subduction of oceanic crust at trenches

• Erosion of oceanic crust at mid-ocean ridges and accumulation at trenches

• Stability of oceanic crust at both mid-ocean ridges and trenches

• Expansion of oceanic crust at trenches and contraction at mid-ocean ridges
