No problem! XD Any more questions?

OpenStudy (anonymous):

yes this is the last one. Alfred Wegener’s theory of continental drift was supported by many lines of evidence. Continental shapes match. Fossil patterns, rock patterns, and climactic evidence also indicated that the continents were once one landmass. Why was his hypothesis of continental drift rejected by most scientists of his day? A. Ages of rocks on different continents did not support Wegener’s theory B. Wegener’s reputation was not great enough to convince scientists that he was correct. C. Wegener’s theory did not explain the magnetic patterns of the sea floor. D. Wegener could not explain the force or natural process that made the continents drift (or move).

OpenStudy (bioepic):
