While making this claim, he had a collection of evidence to support it. This means it does not absorb, emit or reflect visible light, gamma rays, ultra-violet rays etc. EVIDENCE FOR CONTINENTAL DRIFT continents look like puzzle pieces and seem to fit together. In addition South America and Africa looked like they could fit together like puzzle pieces. Genetics. Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. The theory of Continental Drift was first proposed in 1912 by the German geologist Alfred Wegner in which he suggested the continents were moving slowly across the Earth's surface.

An example of this is the earliest known reptile, the mesosaurus. Which is an example of geological fit evidence? Impact craters have been found both on dry land and on the ocean floor. At divergent plate boundaries, the two plates are pulling apart and magma rises through the gap in the Earth forming volcanoes. As they collide, the pacific plate is subducted under the continental Eurasian plate. Was the United States justified in going to war with Mexico. The fact that the seeds would have been unable to be blown or floated to these continents proves that these continents were once together. 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.

First samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached and the sediment cover is thinner near the ridge. What evidence supports the theory of ocean floor? Fossils - certain fossils preserved in rocks of the same age but from different continents. The main concepts that help round Abstract The study of geomorphology is an academic discipline related in explaining the earths surface and to understand the processes which create and modifies landforms. The global inspection reveals an imbalance of areas of lands and sea and almost infinite variation of shapes which illustrates the continental and oceanic areas. Another indication of continental drift is tectonic activity and seafloor spreading. However, these different paths are reconciled by joining the continents in the manner proposed by Wegener. If you take a look at a map of the earth today, you will see the current locations of broken land masses that constitute the earth.

Answer 5: Fossils are formed when living organisms (plants or animals) die and become buried in dirt, sand or mud. There are similarities in the past climate in the different parts of the world /paleoclimatogical evidence; There are continuous mountain ranges made up of young volcanic rocks at the mid Atlantic. Wegener's Puzzling Evidence 1. One evidence of this is the existence of the same animals and plants on the different continents. So, the fact that these organisms could not swim through the vast water bodies helps to substantiate the fact that the continents were once together to allow distribution of these organisms in various continents where their fossils were found on.

Essay Service Examples Science Continental Drift. One of the strongest pieces of evidence is Continental break up/fit, this is the idea that the continents were once joined together. Aside from the congruency of continental shelf margins across the Atlantic, modern proponents of continental drift have amassed impressive geologic evidence to support their views. When this occurs, the sea floor grows wider, pushing the two continents apart. 1. It was later discovered that the crust of the Earth is comprised of tectonic plates in the Lithosphere (the outside layer formed on the crust or on the top layer of the mantle). Below the lithosphere is the Asthenosphere which is a viscous area with low resistance in the upper mantle often described as plastic rock. Its, therefore, impossible that the seeds of the fern were blown by wind or floated across the ocean to have that kind of population on these 5 continents.
