Final answer:
Technology has revolutionized the study of geography by providing tools such as GIS, remote sensing, and GPS for accurate mapping, analysis, and visualization of spatial data.
Step-by-step explanation:
The subject that helped the field of geography to expand is Technology. Technology has revolutionized the study of geography by providing tools such as Geographic Information Systems (GIS), remote sensing, and global positioning systems (GPS), which allow for accurate mapping, analysis, and visualization of spatial data.
These technological advancements have made it possible to collect and analyze large amounts of geographic data quickly and efficiently, leading to exponential growth in the understanding and application of geography.
For example, satellite imagery has enabled scientists to track changes in land cover and identify patterns of urban growth, while GPS technology has facilitated navigation and mapping of previously uncharted regions.
