- 1. Tectonics is the scientific study of the processes involving the formation and movement of the Earth's lithosphere, including the continents and ocean basins. These processes can involve the movement of tectonic plates, earthquakes, volcanic activity, and mountain-building. Tectonics plays a crucial role in shaping the Earth's surface and is fundamental to understanding the geology of our planet and the distribution of natural resources.
