Final answer:
Geographers use scale of analysis to examine geographic phenomena at different levels and gain a comprehensive understanding of their influence.
Step-by-step explanation:
When geographers talk about scale of analysis, they are referring to the level at which they examine a geographic phenomenon or issue. It refers to the extent or size of the area being studied. Geographers can analyze patterns and processes at different scales, such as local, regional, national, or global scales.
For example, if geographers are studying the spread of a disease, they may analyze it at a local scale by looking at the transmission within a neighborhood, or they may analyze it at a global scale by studying the disease's spread across different countries.
By using different scales of analysis, geographers can gain a more comprehensive understanding of how geographic factors influence various phenomena and make predictions about future trends.
