Question
Maps produced by Marie Tharp and Bruce Heezen were some of the first pieces of evidence for this process. For 10 points each:
[10m] Name this process which creates mid-ocean ridges. Vine, Matthews, and Morley confirmed the existence of this process with paleomagnetic data.
ANSWER: seafloor spreading [accept seafloor spread; prompt on descriptive answers such as creating new (oceanic) crust; prompt on continental drift; prompt on, but DO NOT REVEAL OTHERWISE, plate tectonics]
[10h] Seafloor spreading was popularized by this Princeton geologist, who hypothesized that it was caused by mantle convection in his 1962 study “History of Ocean Basins.”
ANSWER: Harry Hess [or Harry Hammond Hess]
[10e] Seafloor spreading provides a mechanism for the movement of these objects. Continental drift occurs as these features “float” on top of the asthenosphere.
ANSWER: tectonic plates
