Final answer:
The correct example of geographer's work is 'b. Geographers use satellite imagery' which allows for the observation and analysis of spatial data. They employ various methods including the creation of maps to communicate information about the earth's surface.
Step-by-step explanation:
The work of geographers is diverse, incorporating various methods such as scientific, humanistic, and geospatial techniques to study the earth's surface. Among the options provided, the correct example of how geographers do their work is 'b. Geographers use satellite imagery'.
This technique allows them to observe and analyze spatial data. They create and use maps as a common method of communicating spatial data about the earth's surface. Satellite imagery assists in examining the earth's physical characteristics, its inhabitants, and cultures, as well as phenomena such as climate.
Additionally, geographers might use other methods like surveys that include spatial questions or the study of environmental geography, which requires an understanding of both physical and human geography.
Geographers' work often involves looking at spatial (space) and temporal (time) relationships of data, and geography in itself is defined as the spatial study of the earth's surface.
