Name all 7 continents North America South America Africa Antarctic Australia Europe Asia Pangaea Pangaea is the name for the original super continent Pan all G aea Earth The continents looked like they might fit together like puzzle pieces. In 1812, Alfred Wegener presented his scientific theory called “Continental Drift”. It was based on his belief that the continents had drifted apart from one another.. Pangaea. Wegener ‘s hypothesis was that all the continents had once been joined together in a single landmass and have since drifted apart.. Continental Drift. Objectives. Summarize Wegner’s hypothesis of continental drift. Describe the process of sea floor spreading. Identify how paleomagnetism provides support for the idea of sea floor spreading. Zach Daniel White.

Why does it matter?. “An antidepressant that brought relief to only seventy percent [of patients] would be a valuable treatment if it did so in one week and had few side effects. Unfortunately, given the current clinical trial methods and placebo-response rates, such an antidepressant, regardless of its true efficiency, would not have more than a fifty percent chance of looking better than placebo.
