Web5.01.3.3 Sea-Floor Spreading In the 1950s, the biggest topic in paleomagnetism was continental drift rather than polarity reversals. Two groups from England led by Keith … Webpaleogeography, also spelled palaeogeography, the ancient geography of Earth’s surface. Earth’s geography is constantly changing: continents move as a result of plate tectonic interactions; mountain ranges are thrust up and erode; and sea levels rise and fall as the volume of the ocean basins change. These geographic changes can be traced through the …
