Here's a breakdown:
* Geology is a broad field that encompasses the study of the Earth's physical structure, composition, and history.
* Tectonics is a specific area within geology that focuses on the movement of the Earth's tectonic plates and the resulting formation of mountains, earthquakes, volcanoes, and other geological features.
* Geomorphology is another area that studies the shape of the Earth's surface and the processes that create and change it, including erosion, weathering, and deposition.
So, while "geology" is the overarching term, "tectonics" and "geomorphology" are specific subfields that directly address the movements and creation of the Earth's surface.
