Question

which evidence supports the theory of plate tectonics? view available hint(s)for part a the glomar challenger found younger rocks and less sediment cover when approaching oceanic ridges. devonian-age rocks and fossils are found on all continents. an earthquake occurred with its focus in michigan. intrusive volcanism results in slower cooling and larger mineral crystals than extrusive volcanism. the magnetic field of earth reverses regularly.

Answer 1

Plate tectonics is a theory that explains the movement of Earth's crust and the formation of geological features. Evidence supporting this theory includes fossils, rock layers, geological features, and the Earth's magnetic field.

Step-by-step explanation:

Plate tectonics is a theory that explains how slow motions within the mantle of Earth move large segments of the crust, resulting in a gradual "drifting" of the continents as well as the formation of mountains and other geological features. Evidence supporting the theory of plate tectonics includes fossils of ancient sea life on dry land far from oceans, the arrangement and order of rock layers, and indications of past volcanic eruptions, earthquakes, and erosion shaping the Earth's surface. Additionally, the regular reversal of the Earth's magnetic field, as observed in rocks near oceanic ridges, provides further evidence for plate tectonics.

In summary, the theory of plate tectonics is supported by various lines of evidence, such as fossils, rock layers, geological features, and the magnetic field of the Earth.
