Question

2.)Discuss 4 evidences in support of theory of plate tectonics (not same as Wagner's

evidence)
1

Answer 1

There are four main evidences to support the theory of plate tectonics: seafloor spreading, earthquake and volcanic activity patterns, hot spots and plate movement, and continental drift.

Step-by-step explanation:

Four Evidences in Support of Plate Tectonics:

1. Seafloor Spreading: Mid-ocean ridges and magnetic striping on the ocean floor provide evidence of seafloor spreading, supporting the theory of plate tectonics. As new crust is formed at these ridges, it pushes older crust away.
2. Earthquake and Volcanic Activity Patterns: The distribution of earthquakes and volcanic activity along plate boundaries supports the theory of plate tectonics. Most earthquakes and volcanoes occur at plate boundaries, indicating the movement and interaction of tectonic plates.
3. Hot Spots and Plate Movement: Hot spots are stationary areas of volcanic activity, such as the Hawaiian Islands. The movement of tectonic plates over these hot spots supports the theory of plate tectonics.
4. Continental Drift: Fossils and geological features that match across continents provide evidence for continental drift, a major component of plate tectonics. These similarities suggest that continents were once connected and have since drifted apart.
