Answer:
For a mountain that is 850m high with contour interview of 50m, the contour lines will be 850m divided by 50m which is 17 contour lines.
Step-by-step explanation:
Contour line is a line drawn on a topographic map to indicate the ground elevation or depression while contour interval is the vertical distance or difference in elevation between contour lines.
If the contour lines are equally spaced it indicate that the hill has a uniform slope but when the spacing are not equal it indicate non uniform slope.
If the interval of the contour lines are in increasing order, the contour indicate a hill but if it is decreasing it indicate a valley.
