Each contour line represents a different elevation. If they touched at any point, that would mean that point would have 2 different elevations at once, which doesn't make any sense. They can get really close if there is a steep drop, but they never touch.

They can never cross but they converge as the represented ground steepens, so they touch in appearance on paper when representing a vertical face of height at least equal to the difference between two consecutive lines.
V
A line intersect is a point on a line where another line or object crosses the line.
Perpendicular lines are where a line crosses another line and forms 4 right angles on all 4 sides but a intersecting line only crosses another line
because the world would explode
lower.
straight line
When a contour line crosses a river or stream, they make a "V" shape and points to the direction the river is flowing.
V
contour interval
A perpindicular line is when a line crosses another line. Simple as that :)
contour lines can never cross. The closer the contour lines are, the steeper the land gets. If you move from one line to another, the elevation becomes different.

The Asymptote
It means the slope is steeper
it is a contour line of elevation Control index contour, or just index contour
•Contour Line: locus of points with constant elevation. •Dense information along the contour line. •Hardly any information across the contour line.
