A. Find the difference between the index contours and divide by the number of spaces between the contour lines.

Explanation:

In Geography, topography can be defined as the shape and structure of the Earth surface. Thus, a topographic map is used to graphically describe this features.

A topographic map can be defined as an accurate and detailed graphical (two-dimensional) description, representation or records of both natural and man-made (artificial) features on the surface of the Earth.

Simply stated, it uses contour lines to represent or denote points of equal elevation above sea level such as mountains, hills, plains, valley etc.

Basically, the two-dimensional model of a topographic map graphically represents the height of a mount and the steepness of a slope through the use of contour lines.

Contours can be defined as imaginary lines used for connecting locations that are having similar elevations on the Earth's surface. These contour lines are typically used for modeling the three-dimensional shape of the Earth surface in a topographic map.

In this scenario, Amy is hiking using a topographic map. To find the contour interval of the map, she should find the difference between the index contours and divide by the number of spaces between the contour lines.

Additionally, topographic maps have various real-life applications such as hunting, surveying, fishing, camping, urban planning, hiking etc.
