Search and Rescue Technician Level I (SARTECH I) Practice Test

The term that best describes the difference in elevation between adjacent contour lines on a map is known as the contour interval. This interval is crucial for understanding the topography of an area, as it indicates how steep or gentle the terrain is by showing the vertical rise or fall in elevation represented by each contour line. A smaller contour interval indicates a more gradual change in elevation, while a larger interval suggests a steeper gradient.

Understanding contour intervals aids search and rescue technicians in navigation and terrain analysis, as they can evaluate potential hazards, establish routes, and assess the overall landscape effectively.
