Illustrate a mountain top that is 850 m high using a contour interval of 50 m

Contour: a layout particularly of a bend or a sporadic figure.  

Explanation:

Contour interval: The vertical separation or the distinction in the height between the two shape lines in the geographical guide.

A form interim in reviewing is the vertical separation or the distinction in the rise between the two shape lines in a geological guide.

A contour line is a line drawn on a topographic guide to demonstrate ground height or gloom.

A contour interval is the vertical distance or difference in elevation between shape lines. Index contours are striking or thicker lines that show up at each fifth contour line.
