As they are the same density, they break when they collide and are forced upwards instead. This apparent fit is due to the fact the continents were once connected and have since moved apart in what has been called continental drift . Dark matter is an incredibly elusive force which is necessary for many modern theories that describe the movement of galaxies and effectively all of the major elements of the universe. Fossils of the Mesosaurus, an ancient freshwater reptile found in the southern parts of South America and Africa, also indicate that the two continents could have once been one solid continent that drifted apart, since the reptile could not have swum across the ocean.

Biogeography. 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. This theory was met with skepticism and was largely dismissed by the scientific community for many years. Finding fossils of the Mesosaurus on the southern hemispheres of both continents is a further indication that the two continents were once together and later drifted apart. What are 2 important fossils used to support continental drift? The present continents appear to fit together as pieces of a larger landmass. 2 What are some of the major pieces of evidence for the theory of plate tectonics? The second theory was that the continents had been in contact with each other millions of years ago, and had somehow drifted apart. When this occurs, the sea floor grows wider, pushing the two continents apart. In 1937 Alexander L.

Plate Tectonics Theory of Continental Drift The continental drift hypothesis was developed in the early part of the 20th century, mostly by Alfred Wegener. Glossopteris was Fossil from fern. As a result of movement of the supercontinent, Pangaea split into two super landmasses namely Laurasia and Gondwanaland. Today we know that the continents rest on massive slabs of rock called tectonic plates. After Wegener died on an arctic expedition in 1930, only a handful of loyal supporters continued to promote his ideas. The Fossil Record. Earthguide: Online Classroom Definition: Pangaea (ucsd.edu)There were also many supercontinents that existed before Pangaea such as Ur which is said to have existed 3 billion years ago, Columbia which existed 2.5 billion years ago and Rodinia which existed 1.3.-1.9 billion years ago. The hypothesis addresses how the continents and oceans are distributed. Alfred Wegener proposed the Continental Drift Theory in 1912. However, would you believe if someone told you that these broken land masses were once connected to each other as one huge supercontinent? One indication of this possibility is the appearance of the western African and eastern South American coasts, which look like two interlocking jigsaw puzzle pieces. One of the strongest pieces of evidence is Continental break up/fit, this is the idea that the continents were once joined together. His ideas attracted much attention in the 1920s and generated much controversy. However, these different paths are reconciled by joining the continents in the manner proposed by Wegener.

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. Fossils of the seed fern Glossopteris were too heavy to be carried so far by wind. He provided evidence that mountain ranges occurring on opposite continents matched up pretty well when brought together. Over the course of millions of year ago, this gradual movement caused the once combined supercontinent to separate into 7 continents you witness in the present day. According to National Geographic, sea floor spreading and plate tectonics indicate that the continents do move or shift, which supports continental drift theory. Darwins finches from the Galapagos Islands. The curves for Europe and North America, for example, are reconciled by the assumption that the latter has drifted about 30 westward relative to Europe since the Triassic Period.

Continental drift theory was given by Alfred Wegener in 1915. What evidence supports the theory of continental drift? As the divergent plates move apart and new magma rises from the mantle it will record the current alignment of the North Pole. Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. There is variety of evidence that supports the claims that plate tectonics accounts for (1) the distribution of fossils on different continents (2) the occurrence of earthquakes and (3) continental and ocean floor features including mountains volcanoes faults and trenches.
