The realization of South America and Africa connect together like a puzzle is not the only fact that Alfred and some scientists now has found. In the article, The Distribution of Fossils and Plate Tectonics, it said that Alfred spent his life traveling around the world looking for fossil evidence to prove his theory correct because that is what was also recognized when he formed his theory. The article also mentioned that the evidence he established was “similar plants and animal fossils on the west coast of Africa and the east coast of South America.” Furthermore, other fossil evidence that was found about plate tectonics is how plant fossils “in the Antarctic and glacial deposits in the arid Vaal River Valley in Africa.” For example, in …show more content…
Geologists has mapped the ocean floor and they learned that there is a large mountain range that lies underwater in between the continents called the mid-oceanic ridge. The plates are actually shifting because they are carried on currents that are in the upper mantle. These convection currents are what is causing the oceanic ridges to rise and create mountains and new crust. In the article Plate Tectonics it says that, “the magma from the mantle rise up between the tectonic plates and spread outwards”, and when that happens the crust moves slowly dragging the continents with them. Also, there are specific types of boundaries that prove the floor we are on is not actually stationary. For example, the convergent boundary. It is where tectonic plates move into one another either pushing against one another creating mountains or one plate rising over another while the other sinks underneath creating mountains as well. Another boundary is the divergent boundary. It occurs on both land and the ocean when the plates are being pushed away from one another. An example of a divergent boundary is the Great Rift Valley in Africa. Finally, another boundary that is none by most people is the transform boundary, also known as the strike-slip fault. It happens when the plates slide against each other sometimes causing …show more content…
According to the video Animated Life: Pangea, Alfred Wegener spent his 20-30 years of his life trying to prove to everybody else that his theory was correct. This is evidence is important because his discovery of the South America and Africa fitting was the first piece of conformation of plate tectonics. Also, fossils from one side of the Atlantic Ocean is on the other side is an piece of evidence that matters because it displays that it would be impossible for the dinosaurs and animals in the past to swim across it. Therefore, proving that Alfred Wegener’s theory was correct because the continents had to be connected for the animal and plant fossils to be in different regions of the world. The fact that the plates traveling is an important piece of evidence because it tells us that the Earth isn’t a solid as some people might think we are, and that there is always a part of the crust that is moving at a slow rate. In the video Animated Life: Pangea there was a speaker named Roger Mccoy, a professor at the University of Utah, said, while referring to the continents and plate tectonics, “And in fact are still moving today.” Based on what is known about plate tectonics, the Earth in 100 million years would more likely be different than what it would look like today. In 100 million years from now the Earth would probably have less land and more waters, meaning the continents
Fossils Tell of Long Ago uses accessible language and illustrations to aid all students in vocabulary and new concept growth. Explicit instructions, reading the book allowed to the class, and allowing conversation among individual students as they work through learning new words will aid ELL students in expanding their word knowledge. Furthermore, having ELL students translate new word to into their native language will help them activate their previous knowledge. Encouraging all students to be actively engage in learning words will ensure that ELL students and all students will gain knowledge and make connections to new words.
The theory of plate tectonics was first developed by Alfred Wegener. He concluded that the continents seem to have a similar shape and could potentially fit together. This suggested that they were at one time joined together as part of 2 super continents called Gondwanaland and Laurasia was in the north. This theory was said to be proven by the discovery of fossilised remains of a mesosaurus that were found on the coasts of Brazil and Gabon. Sea floor spreading is another theory that supports the idea of plate tectonics; this theory discovered that rock is being formed under the ocean as a new sea floor. Sea floor spreading was shown in the Atlantic, where it is believed the Eurasian and North American plates are moving apart on a
Was pangea real or is it all a mystery,nobody knows if pangea is real because it still remains a mystery I think,let's find out.long long ago the earth wasn't seven continents it was just one big landmass surrounded by a ocean called panthalassa. Alfred winger was the person that found out about Pangea. He figured out that Africa and South America fit together. And also from my own experience I was watching The History Channel then there were two of the same dinosaurs in Africa and South America at the same tip of each continent that's why they know that Pangea is real because dinosaurs cannot swim across a whole ocean .
Refer to the images above. Discuss in detail the two pieces of additional evidence that supported Wegener’s theory, now known as the theory of plate tectonics.
The earth’s surface is made up of many separate pieces called tectonic plates. These tectonic plates are in constant movement. This
Wegener also found some evidence for continental drift from fossils of plants and animals. The same type of plant/animal fossils are found on continents that are now far apart from each other. These Plants & Animals would not have been able to swim the oceans.
Plate tectonics is the scientific theory that attempts to explain the movements of the Earth's lithosphere that have formed the landscape features we see across the globe today” (Briney). Geology defines “plate” as a large slab of solid rock, and “tectonics” is part of the Greek root word for “to build.” Together the words define how the Earth’s surface is built up of moving plates. The theory of plate tectonics dictates that individual plates, broken down into large and small sections of rock, form Earth’s lithosphere. These fragmented bodies of rock move along each other atop the Earth’s liquid lower mantle to create the plate boundaries that have shaped Earth’s landscape. Plate tectonics originated from meteorologist Alfred Wegener’s theory, developed in the early 20th century. In 1912, he realized that the east coast of South America and the west coast of Africa appeared to piece together like a jigsaw puzzle. He further examined the globe and deduced that all of Earth’s continents could somehow be assembled together and proposed the idea that the continents had once been linked in a single supercontinent called Pangaea. To explain today’s position of the continents, Wegener theorized that they began to drift apart approximately 300 million years ago. This theory
To support the theory of continental drift is through topography, surveying the floors of oceans, charts of rock magnetism, and statistics on rock ages (Trefil & Hazen, 2010). At one time scientist believed that the deep ocean floors were flat; accumulating the sediment that progressively wore away from the prehistoric landmasses (Trefil & Hazen, 2010). However, they discovered steep-walled valleys and elevated highlands. This was evidences that just as the continents are transformed and are active, so to is the seafloor (Trefil & Hazen, 2010). The Mid- Atlantic Ridge, positioned in the central part of the Atlantic Ocean, is recorded to be the longest mountain range on this planet. Volcanoes, lava flow, and earthquakes are a source of
The earth has been through a lot of changes throughout time. It used to be thought that the continents were locked in their positions and couldn’t move, but in 1915 Alfred Wagner came up with a theory about continental drift (Tarbuck and Lutgens, 2015). While unsure of the process that happened at the time, Wagner also came up with the idea that all the continents in existence today were once all connected as one giant continent known as Pangea. This idea is supported by the findings of similar rocks or fossils in multiple locations separated by large water bodies. Thanks to more tools and funding, the oceanic ridge system was found and by 1968, the theory of plate tectonics was introduced (Tarbuck and Lutgens, 2015). This theory
Wegener provided numerous explanations and documentation in support of his continental drift theory. He provided two fossils as evidence. Glossopteris because it had been found on several continents that were widely separated. Glossopteris, also known as a seed fern fossil, was too large to be transported by the wind. The other was Mesosaurus which was a small aquatic freshwater reptile (Lutgens & Tarbuck, 2014, p. 154). Other scientists believed this was possible because land bridges had once existed or explained it away as drafting. Wegener most likely did not offer fossil sharks or jellyfish as evidence due to the fact that these fish inhabit all major oceans on the planet.
Fossil evidence is very important for our understanding of plate tectonics theory. Similar animal fossils have been found on the South American and African continents. These fossils suggest that the continents were once joined together. Fossils of an extinct reptile, named a Mesosaurus, have been found in southern Africa and South America. Scientists believe that the only explanation for this fossil being found on these two continents is that they were once joined and have become separated due to plate movements. Plant fossils, such as a fossil of the Glossopteris tree have been found in several countries across the Southern Hemisphere such as India, Australia and even Antarctica. The discovery of these fossils prompted scientists to conclude that these countries must once have been joined in one large land mass. The discovery of such fossils as this in Antarctica gives additional weight to this theory as vegetation cannot survive the harsh Antarctic environment suggesting that if vegetation has been able to grow previously, the positioning of the continent must have been
The short story, “Hills like White Elephants” by Ernest Hemingway is about a young couple travelling in Spain, who are arguing over a life changing and burdening situation they have found themselves in. The unnamed man is identified as the American, while the women has the nickname of Jig. It is never actually discussed what exactly they are arguing over, but it is implied that they are discussing the possibility of an abortion. Hemingway uses setting and symbolism to convey the discussion of abortion and leads the readers to conclude for themselves.
Eventually the crew and the Deep Sea Drilling Project found what they were looking for. They drilled 17 holes at 10 different sites along the oceanic ridge between South America and Africa. The recorded samples had definitive proof for continental drift and seafloor renewal at rift zones. Continental Drift was a theory created by a German scientist named Alfred Wegener and basically what the theory means is that the Earth’s continents (North America, South America, Europe, Asia, Antarctica, Africa, and Australia) were not all where they are now on the map and will not
The expression "morale" has been characterized from various perspectives. In any case, every one of the definitions spin around the state of mind towards work for the achievement of association objectives. William Spriegel has characterized assurance as the agreeable disposition or emotional wellness of number of individuals who are identified with one another on a few premise. As indicated by Alexander H. Leighton, "Morale is the limit of a gathering of individuals to pull together industriously in quest for a typical reason." These definitions uncover that spirit is the level of excitement and readiness with which the individuals from a gathering work to perform their assignments. Spirit speaks to a composite of emotions, mentalities and
: Fossils are the remains or traces of ancient organisms which have been preserved. For example, a fossil can exist as skeletal remains or even as a footprint. Such organisms are subjected to a slow rate of decaying since they have been rapidly buried under conditions that facilitate this. It is common for fossils to occur as hard-bodied organisms as these are more resistant to environmental influences. Fossils are usually found embedded in rock. The layers of rock are of different age and makeup. Hence fossils found in one layer would vary in characteristics from those found in another layer. They can be observed and analyzed through visual as well as radiometric means so that the age and morphology can be determined. These features indicate
