- Theory of Plate Tectonics Summary
- Explains movement, formation, and interactions of Earth's lithospheric plates
- Crucial for understanding geological processes
- History of Plate Tectonics
- Alfred Wegener proposed hypothesis of continental drift in 1912
- Use of observations and evidence to support his hypothesis
- Development of Plate Tectonics Theory
- New discoveries about earthquakes, magnetism, and age of rocks supported the theory
- Explanation of movement of Earth's land masses
- Evidence of Plate Tectonics
- Explanation of geographical processes, earthquakes, and volcanic activity
- Wealth of evidence supporting the theory
- Tectonic Plates Movement and Boundaries
- Explanation of pattern of earthquakes and volcanoes along plate boundaries
- Fractures and earthquakes occurring at plate boundaries
- Magnetism and Age of the Ocean Floor as Evidence
- Igneous rocks and magnetic minerals provide records of Earth's magnetic field
- Evidence aligns with movement of tectonic plates and supports theory of plate tectonics
