GEOLOGY

Detailed explanation-1: -The closer the contour lines, the steeper the slope. The wider the contour lines, the flatter the slopes.

Detailed explanation-2: -This is because when contours are close together, it means that the slope is steeper. For a quick definition, a contour line joins points of equal and constant values. For example, contours on an elevation have constant heights that are the same on each line in a topographic map.

Detailed explanation-3: -Closely spaced contour lines indicate steep slopes. • Widely spaced contour lines indicate gentle slopes or relatively flat areas. • A contour line that forms a closed loop with no other contour lines inside indicates a hilltop.

Detailed explanation-4: -If the distance between the contour lines is great, the slope is gentle.

Detailed explanation-5: -Contour lines indicate the steepness of terrain. Contour lines connect points that share the same elevation: Where they’re close together (they never intersect), elevation is changing rapidly in short distance and the terrain is steep.
