Several symbols are present on the map, such as triangles and circles. What do these symbols typically represent in a geological context?

In a geological context, the triangles shown on the map, particularly along plate boundaries, typically represent convergent plate boundaries, often indicating subduction zones where one tectonic plate is sliding beneath another. The circles might represent mid-ocean ridges or other types of plate boundaries, but without a legend, this is an interpretation based on common cartographic conventions for geological maps.
