Here's why:
* Geology is the study of the Earth's physical structure and history. This includes the formation, composition, and movement of continents, which are key aspects of plate tectonics.
* Geography focuses on the Earth's surface, including its features, climates, and human populations. While it does study continents, its primary focus is not on their formation and movement.
* Oceanography focuses on the oceans, while meteorology studies weather and climate.
* Astronomy is the study of celestial objects, and biology is the study of life.
Therefore, geology is the most directly relevant discipline for recording the shapes and locations of continents.
