What is the study of the shape and size of the earth and its features called?

The study of the shape and size of the Earth and its features is accurately referred to as Earth Geometry. This field specifically focuses on understanding the dimensions, spatial relationships, and geometric characteristics of the Earth’s surface, which encompasses its size and the overall shape, including its curvature and physical features.

In contrast, cartography pertains to the art and science of map-making, which involves representing geographic information visually rather than studying the Earth’s dimensions directly. Geography is a broader discipline that deals with the interactions between people and their environments, including cultural, physical, and human geographical aspects. Geomatics involves the collection, analysis, and interpretation of data related to the Earth’s surface but does not specifically focus on just the shape and size of the Earth. Thus, Earth Geometry is the most precise term for the study in question, emphasizing its geometric aspects.
