Document Summary
According to wenger"s hypothesis of continental drift, all continents were once formed and attached and formed a single land mass that he called: pangaea. What is the relationship between the coastlines on the east side of the. Atlantic and those on the west side: continents on the east side fit snugly with those on the west. When wegener compared rock units now exposed on different continents bordering the atlantic ocean, what did he discover: fossils of identical land dwelling species occur on continents that are now separated by vast oceans. Why did most geologists initially oppose wegener"s hypothesis of continental drift: wegner could not explain how or why continents move. Why can samples of basalt exhibit paleomagnetism: the dipoles of tiny magnetite grains in basalt align with the earth"s fields as the basalt cools and stay that way. Today, what is the favored explanation of apparent polar-wander paths: continents drift with respect to relatively fixed magnetic poles.
