Document Summary
Part 1: continental evidence, glacial evidence, paleoclimatic evidence, fossil evidence, matching geologic units, his importance, alfred wegener. What is paleomagnetism: earth"s magnetic field, magnetic inclination. Wrote the origins of the continents and oceans in 1915. Proposed that land masses slowly move (continental drift) Said that the continents fit together too perfectly for it to be a coincidence. Evidence of late paleozoic glaciers found on five continents. Some of this evidence is now far from the poles. These glaciers could not be explained unless the continents had moved. Wegener predicted rocks defining pangaea climate belts. Identical fossils found on widely separated land masses. Distinctive rocks assemblages and mountain belts match across the. Similar to a bar magnet because it has a north and a south pole: earth"s two north poles, magnetic declination. Two north poles: a geographic north pole and a magnetic north pole. The geographic north pole lies on an axis in which the earth spins.
