Those continents are South America and Africa.

4 pieces of evidence of continental drift. There are 3 main kinds of boundaries. The continents fit together like a puzzle. Although the evidence for continental drift was extremely strong, scientists rejected the idea because no mechanism for how solid continents could move around on the.

Glacial deposits in the tropics and coal deposits in Antarctica. Plate tectonics theory is taught in science classrooms around the world, but just 50 years ago it was a hotly contested theory. Fossils - certain fossils preserved in rocks of the same age but from different continents.

The main problem with Wegener's hypothesis of Continental Drift was the lack of a mechanism. Other fossil evidence also supports the theory of continental drift. Why didn't people believe Alfred Wegener?.

Introduction to theory and evidence of continental drift. Wegener, Galileo and Darwin. Evidence for continental drift is now extensive, in the form of plant and animal fossils of the same age found around different continent shores, suggesting that these shores were once joined.

Snider-Pellegrini’s map showing the continental fit and separation, 1858. Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. Apparent Affinity of Physical Features.

This is a picture of glacier scars found in Africa. When Alfred Wegener first made his case for continental drift, he relied on two main lines of argument:. Hideo Kozima, in The Science of the Cold Fusion Phenomenon, 06.

1.5.4 The dawn of a science. Over time, these continents have broken apart and moved apart through continental drift. Four of them are as follows:.

As we now know well, Wegener, a geologist and geophysicist in Germany, developed the grandiose idea of continental drift. Continents and fossils fitting together/matching-up like puzzle pieces. Some of the most dynamic sites of tectonic activity are seafloor spreading zones and giant rift valleys.

Indications of widespread glaciation from 380 to 250 million years ago are evident in Antarctica , southern South America, southern Africa, India , and Australia. In geology, a supercontinent is the assembly of most or all of Earth's continental blocks or cratons to form a single large landmass. List and Describe the Evidence for the Plate Tectonics Theory.

Geologic features and mountains match across oceans. One is quite simple i.e. The continents look like they could fit together much like a puzzle pieces that have been drifted apart.

Although Alfred Wegener was able to produce a viable hypothesis with evidence and specifically state the theory, it should be noted there were previous. Continents fit like Puzzle Pieces. Explain the theory of continental drift.

4 pieces of evidence for continental drift by Alfred Wegener Wegener put together the first comprehensive theory to describe and partially explain the phenomenon, publishing his. 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. The response of scientists in the established research fields has reminded us of an episode of Wegener's hypothesis of continental drift.

The shape of the continents. Continental Drift Theory DRAFT. How does coal distribution support the Theory of Continental Drift?.

Fossils of remarkably similar plants and animals have been discovered on opposite sides of the Atlantic Ocean. ► The coasts of the continents surrounding the Atlantic ocean could, if the continents were moved closer, fit together like a jigsaw puzzle. Rocks on either side of the Mid-Atlantic Ridge - same age c.

Globe C shows the continents drifting away from each other a little bit. The bulge of Brazil (South America) seems to fit into the Gulf of Guinea (Africa). The first one labeled A, shows all the continents on Earth broken up as to how they appear today.

Glossopteris - plant remains found in South America, Australia, Asia and Africa. Trained as a meteorologist, he was intrigued by the interlocking fit of Africa. The students will be able to use electronic tools to explore the history of Earth’s surface.

Wegener postulated a massive supercontinent, which he called Pangaea (Greek for “whole land”), as existing about 225. Continental drift was a theory that explained how continents shift position on Earth’s surface. The earliest marine fossils found along the eastern coast of South America and the western coast of Africa date from about 150 to 0 million years ago, suggesting that the Atlantic Ocean did not exist prior to that time.

Seafloor spreading is most dynamic along giant underwater mountain ranges known as mid-ocean ridge s. The distribution of ancient fossils, rocks, and mountain ranges;. Evidence of Continental Drift.

The evidence for continental drift included the fit of the continents;. Evidence later accumulated from other areas of research, but the theory was not taken seriously until well after Wegener's death. Continental drift was a revolutionary scientific theory developed in the years 1908-1912 by Alfred Wegener (10-1930), a German meteorologist, climatologist, and geophysicist, that put forth the hypothesis that the continents had all originally been a part of one enormous landmass or supercontinent about 240 million years ago before breaking apart and drifting to their current locations.

Another indication of continental drift is tectonic activity and seafloor spreading. This theory proposed that the continents moved through the ocean floor and that at one time all the continents had been one big supercontinent. Who proposed the theory and what evidence did he provide to prove his theory.

Another important piece of evidence in the Continental Drift theory is the fossil relevance. Early Evidence for Continental Drift Hypothesis Figure \(\PageIndex{2}\):. Reconstruction of previous position continents created with TimeTrek.

Formulate an illustration of each one. What are these evidence for?. Find lessons on Continental Drift for all grades.

Continental Drift The Theory of Continental Drift is defined as the movement of the Earth’s continents relative to each other, thereby appearing to drift together across the oceanic bed. Sea floor spreading further supports the continental drift theory. Although Abriham Ortelius previously proposed the idea of continents ‘drifting’ Wegener had thought it through in greater detail.

Alfred Wegener brought together several lines of evidence to support his theory of continental drift. Similar fossils have been found at the bottom of the ocean and on land. Some of the evidence supporting the continental drift of the tectonic plates include the presence of similar animals and plant fossils on the shores of various continents, which suggest that they were once joined.

Wegener published this theory of continental drift and claimed that it was supported by several pieces of evidence and that these areas were once joined. The students will be able to identify the evidence for continental drift and locate them on a map. Evidence for Continental Drift Wegener gathered evidence for his hypothesis from fossils, from studies of ancient climate, and from the geology of continents.

The idea that the Earth’s crust is made up of huge tectonic plates that are floating on an ocean of molten hot magma seemed too. The second piece of evidence in support of continental drift came during the late 1950s and early 60s from data on the bathymetry of the deep ocean floors and the nature of the oceanic crust such as magnetic properties and, more generally, with the development of marine geology which gave evidence for the association of seafloor spreading along. 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.

The shape of the continents and the relative positions of glacial till deposits. As the seafloor grows wider, the continents on opposite sides of the ridge move away from each other. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596.

Which statement does NOT summarize one of the lines of evidence used by Alfred Wegener to support his theory of continental drift. In the process of seafloor spreading, molten rock rises from within the Earth and adds new seafloor ( oceanic crust) to the edges of the old. Alfred Wegener died a few years later.

He published a book that explained his theory and many scientists thought he was wrong and didn’t believe his evidence. Alfred Wegener proposed the idea of continental drift to explain why continents' shapes fit together like pieces of a puzzle and why distant continents have the same fossils. Scientists agree that continents rest on rocks called tectonic plates, which shift and move.

However, some earth scientists use a different definition:. The existing theories of continent formation were allowed to survive, with little challenge until the 1960's. Puzzle Piece Fits 2.

For example, the outward curve of the African coast matches the inward curve of the South American coast. Paleontology - fossils match d. New oceanic crust formed between the northern and southern continents, pushing them apart.

The evidence which gave rise to the theory of continental drift -- more correctly called plate tectonics -- includes the following:. Contraction of the earth caused folded mountains to form. Set forth in 1912 by Alfred Wegener, a geophysicist, and meteorologist, continental drift also explained why look-alike animal and plant fossils, and related rock formations, are found on different continents.

The theory of continental drift was first developed in the early 1900s by Alfred Wegener, a German scientist. Apparent Affinity of Physical Features. Evidence of extinct species on nearby continents the fitting together of neighboring continents like jigsaw puzzle pieces the fossil evidence of a former tropical climate non-tropical continents the existence of coal deposits in similar areas of neighboring continents.

Evidence to Prove That Pangaea had Existed / Evidence of Continental Drift. Like a jigsaw puzzle, the Earth’s crust has 15 or separate pieces of minor and major plate tectonics. These pieces are the plate tectonics that ride on soft melted rock underneath.

Fossils Wegener learned that the fossils of an ancient reptile, Mesosaurus (MEHZ-uh-SAWR-uhs), had been discovered in South America and western Africa. This evidence gave Alfred Wegener the idea of Continental Drift. The concept was independently and more fully developed by Alfred Wegener in 1912, but his hypothesis was rejected by.

Which of the following was NOT a piece of evidence that Alfred Wegner used to support his Continental Drift theory. Evidence in Support of the Continental. Theory of the Continental Drift.

How do distinctive rock strata support the Theory of Continental Drift?. This small reptile lived about 270. The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones' locations.

Puzzle Fit, Fossil evidence from animals that were once on the same continent, geologic evidence like. With his death, the Continental Drift Theory was quietly swept under the rug. He suggested, based on evidence he had gathered, that the continents are actually.

Free interactive resources and activities for the classroom and home. For example the fossils of the freshwater crocodile found in Brazil and South Africa. "a grouping of formerly dispersed continents", which leaves room for interpretation and is easier to apply to Precambrian times, although a minimum of about 75% of the continental crust then in existence.

What are four pieces of evidence supporting continental drift?. How do the continental coastlines support the Theory of Continental Drift (Pangaea Theory)?. And the locations of ancient climatic zones.

The first evidence supporting the theory of continental drift was _____. According to Wegener, these forces would become effective when applied over many million years, and the drift is continuing. Wegener’s first piece of evidence was that the coastlines of some continents fit together like pieces of a jigsaw puzzle.

All continents were together as a supercontinent (Pangaea). Shapes, and seafloor structures to provide evidence of the past plate motions. Another proof is plant and animal fossils and the distribution of the different fossils and rocks that are all the same.

He could not identify the driving force that was able to make the continents move. This indicates that these continents had to be once joined together because the extensive oceans between these land masses act as a type of barrier for fossil. Evidence in support of Continental Drift.

If you look at the shape of the coastlines of continents, you can see that they would easily have fit together in the past. During Wegener’s time, the idea was met with hostility. Identify and explain at least 4 types of evidence.

Evidence for continental drift A map of the continents inspired Wegener's quest to explain Earth's geologic history. Explain how fossil distribution supports the Theory of Continental drift. But after his death, a large body of evidence showed that continents do indeed move.

6 Pieces of Evidence for the Theory of the Continental Drift A theory is an idea that is supported by evidence but not proven to be true. The pieces of evidence Alfred Wegener used to support his theory about continental drift were;. The next globe, labeled B, shows one very large piece of large land where all the continents are connected.

Fossils of a freshwater reptile known as Mesosaurus was found both in South Africa and Brazil. Evidence of Continental Drift Theory Fossil plants and animals clue Fossils of creatures and plants discovered on different continents helped to him push his case that the continents were once locked together before breaking up and drifting away. There are various examples of fossils found on separate continents and in no other regions.
