The theory of plate tectonics states that the Earth's lithosphere, or the outermost layer of the Earth, is divided into several large and small tectonic plates. These plates are in constant motion due to the underlying asthenosphere, which is a semi-fluid layer of the Earth's mantle. The movement is driven primarily by convection currents that occur within the mantle. The plates can interact with each other in three main ways: plates can move apart (divergent boundary), move towards each other (convergent boundary), or slide past each other (transform boundary).
The concept of continental drift, proposed by Alfred Wegener in the early 20th century, offers insight into the history of these plates. Continental drift suggests that the continents were once connected as a supercontinent called Pangaea and have since moved to their current positions. This explains why similar fossils and rock formations are found across continents that are now widely separated.
Continental drift tells us that the plates were once in different positions compared to their current arrangement. It implies that the plates constantly shift and slowly move over geologic timescales. These movements have resulted in the diversification of landscapes and the shaping of Earth's surface, forming mountains, ocean basins, and other geological features. Continental drift is a significant component in understanding the Earth's geological history and continues to influence various processes on our planet.
