Question

i. What are contours?
ii. What does the spacing between the two adjacent contours indicate?
iii. What are the conventional signs?​

Answer 1

i) In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
