How does plate tectonics explain the fossil paradox?
According to the theory of plate tectonics, the continents are not rigidly fixed to the surface of the Earth. In consequence, the map of the Earth’s surface is constantly changing over geological timescales. Some of the most persuasive evidence for this theory comes from the distribution of fossils.
Which of these is evidence for the theory of plate tectonics?
Earthquakes and volcanic activity are also evidence of plate tectonics. Divergent and convergent boundaries are both prone to frequent volcanic activity. Does the lava in volcanoes come straight from Earth’s core? Earth’s core is made of solid iron, not lava, so magma can come directly from the core.
What is fossil evidence?
Fossils are evidence of organisms that have existed. The fossils may consist of clues about the organism, such as its tracks or feces, or they may be a part of the organism, such as a bone or other body part. Fossils give scientists clues about the structure and lifestyle of the organisms.
What is the importance of fossils in identifying the connections of continents?
Finding similarities among the fossil records on different continents provides evidence for the theory that current continents were once connected. The fact that life on each continent is now distinct is another type of evidence.
What two fossil evidence supports plate movement?
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 two pieces of evidence for plate tectonics?
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 are the three theories of plate tectonics?
The three types of plate boundaries are divergent, convergent, and transform. They are described in the following three concepts. Most geological activity takes place at plate boundaries.
Why is fossil evidence important?
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.
Why is fossil evidence usually not enough?
Teeth and shells do not fossilize. Soft-bodied organisms do not readily fossilize. Some fossils are buried too deep for scientists to reach Organisms that are eaten after death are unlikely to fossilize. Movement of Earth’s crust destroys some fossils.
What do the Glossopteris fossils tell us?
Answer: The Glossopteris fossils are the most abundant resources which tells more about the super continent. Explanation: It is believed that this woody plants fossils could be found in every continent as the research records claims that once they used to live on the entire Pangea before continental drift.
What evidence exists to support the theory of plate tectonics?
Evidence that supports the theory of plate tectonics includes distribution of rock formation and fossils, shapes of existing continents, ocean floor features, and seismic and volcanic activity. This evidence shows how Earth’s plates have moved great distances, collided, and spread apart throughout Earth’s history.
How do plate tectonics relate to fossils?
Fossil Distribution. One of the first lines of evidence suggesting the existence of plate tectonics was the discovery of very similar fossils in rock masses separated by vast distances and by ocean expanses. It suggested that those land areas had in the past been connected.
What type of evidence do scientists use for plate tectonics?
List and Describe the Evidence for the Plate Tectonics Theory The Theory of Plate Tectonics. The basic theory of plate tectonics is that along seafloor spreading zones, the continents are separating from one another. Sea Floor Magnetism. Stripes of magnetic material in the seafloor provide strong evidence for tectonic theory. Fossil Evidence. Direct Measurement.
Which is not evidence for plate tectonics?
The presence of glaciers is not evidence for plate tectonics.
