What is the term for mapping based on the visible landscape up to the 1920s?

• A. Surface Geology
• B. Mineralogy
• C. Stratigraphy
• D. Hydrogeology

Answer: (A)

This question is about the terminology for describing maps made from what you can see on the ground. Mapping based on the visible landscape is best described as surface geology. It focuses on the rock types, formations, and landforms that appear at the surface and uses those observations to create geologic maps—often without drilling or subsurface data, which was especially true up to the 1920s when such data were scarce. Mineralogy, on the other hand, studies minerals themselves; stratigraphy deals with the order and ages of rock layers and their relationships; hydrogeology concerns groundwater movement and distribution. So surface geology fits the idea of interpreting and mapping the landscape as it appears on the surface.
