Numerous lines of evidence support the theory of plate tectonics. Based on the mounting evidence, the theory of plate tectonics continued to take shape. Seafloor was spreading away from the mid ocean.
plate tectonics Definition, Theory, Facts, & Evidence Britannica
What evidence supports the theory of plate tectonics? New oceanic crust is created when tectonic plates move apart. What are two lines of evidence that support the theory of plate tectonics (discovered after wegener's death) seafloor spreading:
The plates rip apart at divergent plate boundaries, crash together at convergent plate.
Coastlines on opposite continents appear to fit together. Figure 1.2.1 fossil evidence that. Tuzo wilson was the first scientist to put the entire picture together by proposing the opening and. We will find out in this section!
The new crust preserves the magnetic field orientation of earth. But what exactly is that evidence, and what makes the idea of plate tectonics good enough to become a scientific theory? Which of the following provides evidence for plate tectonic theory? The driver of all this is plate tectonics:
PPT Chapter 2 Plate Tectonics and the Ocean Floor PowerPoint
Earth’s outer shell is broken into tectonic plates that move relative to one another.
All this evidence complied together convinced scientists of the existence of plate tectonics and. Earth’s surface is divided into several dozen plates, which move horizontally. A) the matching of coastlines on continents. There is a great deal of scientific evidence in support of 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. Studies of the magnetic field orientations in rock strata reinforced the case for plate tectonics. The alternating patterns of normal and reversed polarities.

One of the key pieces of evidence is continental drift, which refers to the gradual movement of continents over. Figuring out how this got started, however, has proved.
