In order to determine the difference in the elevation for a hiker, the final elevation and the initial elevation must be subtracted. This can be simply written as:
Difference in elevation= (Final elevation - Initial elevation) for the hiker
= (264-180) m
= 84 meters.
From the map, it can be easily identified that hiker B had the steepest elevation.
In a topographic map, the elevations are often represented in the form of contour lines. These contour lines are usually found to be either closely spaced or widely spaced. The closed contours represent the steeper slope and the widely spaced contours represent the gentle slopes.
The decaying plant matter that is found in bogs results in the production of peat. It is not fully decayed by either acidic or inorganic environmental conditions, rather present or composed of wet-land plant life. it is rich in carbon dioxide. It is also an important source of fuel.
