What two fossil evidence supports plate movement?
Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa.
What are the two main evidence of plate tectonics?
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.
What are the four lines of evidence that support plate movements?
Where can I find fossils that help support the theory of plate tectonics?
Fossils are found in Australia, South Africa,South America, India and Antarctica. When the continents of the southern hemisphere are re-assembled into the single land mass of Gondwanaland, the distribution of these four fossil types form linear and continuous patterns of distribution across continental boundaries.
What happens when two plates carrying continental crust collide?
Plates Collide When two plates carrying continents collide, the continental crust buckles and rocks pile up, creating towering mountain ranges. The Himalayas were born when the Indian subcontinent smashed into Asia 45 million years ago.
What does the convergence of two continental plates produce?
When two continental plates converge, they smash together and create mountains. The amazing Himalaya Mountains are the result of this type of convergent plate boundary. The Appalachian Mountains resulted from ancient convergence when Pangaea came together.
What is the best piece of evidence for plate tectonics?
Fossils are the stongest evidences of plate tectonics. Same plant fossils can be seen in distant continents such as South America and Africa.
What are at least two lines of evidence the support the plate tectonics theory and how do those lines of evidence show support for the theory?
Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed. Some life “rode” on diverging plates, became isolated, and evolved into new species.
What evidence is there that the Earth’s crust moves?
There is evidence to suggest that the plates of the world have moved over time e.g. Pangea, fossils etc. The relationship between tectonic events and plate boundaries.
What is fossil evidence?
Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
What evidence have you discovered to explain how similar fossils could be found on continents that are now separated by vast oceans?
The only way these fossils can be found on continents that are separated by oceans is if the continents were once together (connected). These ancient animals and plants could not have swam across oceans!
What evidence supports the claim that plate tectonics accounts for fossils?
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.
How do scientists reconstruct past plate tectonic movements?
Other life dispersed to new areas as continents reconnected, oceans narrowed, or chains of volcanic islands formed. Finding identical or similar fossils in areas separated by vast distances were some of the first clues that scientists used to reconstruct past plate movement.
What do fossils tell us about the past?
Fossils tell us when and where plants and animals once existed. Some life “rode” on diverging plates, became isolated, and evolved into new species. Other life dispersed to new areas as continents reconnected, oceans narrowed, or chains of volcanic islands formed.
How do plate tectonics affect the distribution of rocks?
Most distributions of rocks within Earth’s crust, including minerals, fossil fuels, and energy resources, are a direct result of the history of plate motions and collisions and the corresponding changes in the configurations of the continents and ocean basins. The history is still being written.
