Which of the following are examples that provide evidence of plate tectonics
1) The distribution of fossils: Fossilized remains of the same species have been found on different continents that are separated by vast oceans. This suggests that these continents were once connected and have since drifted apart due to plate tectonics.
2) Earthquake and volcano distribution: Earthquakes and volcanic activity occur along plate boundaries. This pattern supports the theory of plate tectonics as the plates move and interact, resulting in the release of seismic energy and magma.
3) Magnetic striping on the ocean floor: The ocean floor is basaltic and contains magnetic minerals. When new crust is formed at mid-ocean ridges, these minerals align with the Earth's magnetic field. By analyzing the magnetic striping pattern on the ocean floor, scientists have observed symmetrical patterns that indicate the spreading of the seabed at mid-oceanic ridges, supporting plate tectonics.
4) Continental drift: The fit of coastlines on different continents, such as the matching shapes of eastern South America and western Africa, suggests that they were once joined. This observation is consistent with the theory of plate tectonics, as continents are part of the Earth's plates and have moved over time.
5) GPS data: Global Positioning System (GPS) measurements have shown that different parts of the Earth's surface are moving relative to one another. This movement is consistent with the theory of plate tectonics, as the Earth's plates are constantly in motion.
