The theory of plate tectonics came from the idea of continental drift, which was proposed in the early 20th century by a) max planck. b) gottlob frege. c) alfred wegener. d) werner heisenberg. which geological features most likely prompted the development of the theory of plate tectonics? a) river deltas b) glacier fields c) mountain ranges d) tropical rainforests 35) all but one statement provides evidence supporting plate tectonics, through data collected at the sites of sea floor spreading. that is a) paleomagnetic reversals in specific areas of the sea floor. b) a large occurrence of earthquakes along specific lines within the earth's oceans. c) the presence of unique species in remote locations, such as australia and new zealand. d) an increase in the thickness of ocean crust as you move away from the area of spreading. 36) the origins of the theory of plate tectonics began when german scientist, alfred wegener, proposed the idea of a) superposition. b) continental drift. c) natural selection. d) paleomagnetic reversals. 37) in the early 1900s german geophysicist alfred wegener began to question how the structures on the earth formed over time. he proposed the theory of continental drift to suggest that all continents were once connected and have "drifted" to their current location over time. what was the main reason that wegener's theory received a lot of ridicule from the scientific community? a) no similar fossils were found on different continents. b) there was no data to suggest any change in geologic structures. c) wegener did not give a method on how the continents actually moved. d) the outlines of the continents looked like puzzle pieces that would fit together. 38) mars rotates by 360 degrees on its axis in 24 hours and 39 minutes. which of these is equivalent to 24 hours and 39 minutes on mars? a) a day b) a year c) a week d) a month
