Why does the presence of extinct and transitional forms in the fossil record support the pattern What conclusion did George Cuvier come to after his inspection of the fossil record? Its possible that these vent communities are where the first living organisms on Earth developed. Ocean ridges have elevations that typically rise 2 to 3 km (1.2 to 1.9 miles) above the surrounding seafloor and widths that range from a few hundred to more than 1,000 km (600 miles). He was a difficult scientist to pigeonhole. The narrow zones of earthquakes outline the boundaries of moving plates. First, earthquakes are not scattered throughout the oceans, but instead are confined to narrow, rather continuous bands. First, the topography of the ocean floor was mapped in great detail during and after World War II. Junior High School answer answered What discovery provided strong support for continental drift theory? scientists who found his hypothesis resolved difficulties in their disciplines much better than the Mid-ocean ridges and deep-sea trenches develop at the boundaries of the moving plates. This diagnostic sequence consists of glacial deposits called tillites, followed by sandstones and finally coal measures, typical of warm moist climates. how come alfred and ramus the only people who died, How did his evidence help prove his theory, by figuring out how to explain how they move.

Our editors will review what youve submitted and determine whether to revise the article. Earth's internal processes were previously thought to operate in a vertical fashion, with continents, oceans, and mountain ranges bobbing up and down, without much sideways movement. A scientific idea that was initially ridiculed paved the way for the theory of plate tectonics, which explains how Earths continents move. The two continents are today separated by very vast Atlantic ocean. With this reconstruction of the continents, the structures and stratigraphic sequences of Paleozoic mountain ranges in eastern North America and northwestern Europe can be matched in detail in the manner envisaged by Wegener. Wayne Loel Professor Emeritus of Earth Sciences, Stanford University, California. How does the fossil record support the theory of continental drift Because some minerals within rocks record the orientation of Earths magnetic poles and this orientation flips every 100,000 years or so, rocks near ocean ridges exhibit alternating magnetic stripes.Plate tectonics explains why Earths continents are moving; the theory of continental drift did not provide an explanation.

A. . Answer: According to libretext, Wegener used fossil evidence to support his continental drift hypothesis. One method of determining a dinosaurs weight is by studying the cross-sectional area of a limb bone. Below is a map of the tectonic plates of the earth. 5.5: Continental Drift - Geosciences LibreTexts plausible pictures of past climates. The idea of continental drift was not accepted easily by the scientific establishment. (Scientists discovered later that Pangea fragmented early in the Jurassic Period.)
