Exploring Rational Expressions: Addition and Subtraction

The video explains the theory of continental drift, introduced by Alfred Wegener, and how it evolved into the modern understanding of plate tectonics. It covers the concept of Pangaea, seafloor spreading, and the role of Earth's interior in driving plate movements. The video also discusses the impact of these movements on earthquakes, volcanic activity, and the formation of geologic features like mountain ranges. The rock cycle and its connection to plate tectonics are also highlighted.
