Plate tectonics is a fundamental process that shapes Earth’s surface, driven by internal heat from sources like radioactivity. This theory accounts for various geological features and processes, including volcanism and erosion. Similar geological activities are observed on other planetary bodies, such as Mars and Venus, where tectonics and water erosion have significantly influenced surface formation. Additionally, moons like Miranda exhibit unique features due to tidal heating from gravitatio...
