Wegner also noticed that rocks and mountain ranges across continents looked similar and were similar ages, the belt of ancient rocks of 2,000 million years ago from the Brazilian coast matches with those from western Africa he also noticed that there were similar geological sequences in eastern Canada and Scotland.

Scientists did not accept Wegeners theory of continental drift. When he brought these continents together, the glacier grooves perfectly matched up. Impact craters have been found both on dry land and on the ocean floor. If you look at the current map after the continents drifted away, you find that North America and Africa are far away from each other separated by the Atlantic Ocean. Together these discoveries supported the existence of Pangea. Ferromagnetic minerals such as magnetite acquire a permanent magnetization when they crystallize as constituents of igneous rock.

Terms of Use, Evidence in Support of the Continental Drift: Analytical Essay., Evidence in Support of the Continental Drift: Analytical Essay [Internet]. In support of the continental drift theory, it was established that South Africa, India, Australia and South America all experienced glaciations at the same time. During the early 1960s, the American geophysicist Harry H. Hess proposed that new oceanic crust is continually generated by igneous activity at the crests of oceanic ridgessubmarine mountains that follow a sinuous course of about 65,000 km (40,000 miles) along the bottom of the major ocean basins. Which statement best supports the theory of continental drift quizlet? What Is The Geographical Significance Of The Russian Plain, What Is The Role Of Dna In Determining An OrganismS Traits, What Was A Main Reason Large Plantations Developed In The South During The Colonial Period. Another term for subduction is slab pull which suggests that as the denser oceanic plate is subducted at a convergent margin, they become denser than the underlying mantle and pulls the rest of the plate behind it. Let us know if you have suggestions to improve this article (requires login). Continental drift is the suggestion that over long periods of geological time, the continents of the Earth have moved apart from each other and had once formed almost one single land mass known as Pangaea. Over time the continents change position relative to one another as they move. We can also see that the basaltic rock gets older the further we travel from the mid Atlantic ridge, showing that new basaltic rock is made as the magma rises from the diverging plates. Also, the article explores the idea of if the Kiwi bird came first or the egg. Government programs to settle the land Privacy Policy What are 5 pieces of evidence of continental drift? Heat coming from the interior of the earth triggers this movement to occur through convection currents inside the mantle. The force of subduction can cause volcanoes to erupt and earthquakes to occur around the subduction zone. Molten rock material from Earths mantle rises upward to the crests, cools, and is later pushed aside by new intrusions. Temperature and pressure both increase with depth.

Geological fit evidence is the matching of large-scale geological features on different continents. The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones. For millions of years, all the land of Earth was joined together in a supercontinent, which is known as Pangaea. The evidence for continental drift included the fit of the continents the distribution of ancient fossils rocks and mountain ranges and the locations of ancient climatic zones. A.
