As two contour line are of different heights, it would be impossible for two contour lines to cross. But, the problem is when it comes to printing map details.
If two contour lines cross (touch) it means that they are both at the same height. This can happen on a cliff or steep sided mountain, when the height is so close vertically, that it is easier to show a blank area with a symbol for a cliff or steep mountainside. The symbol used depends on what is used by the producer/printer of the map. The symbol for cliffs should be shown on the map's legend printed on most maps.
Contour lines are elevation so they go up and not across
Each contour line represents a specific elevation, it is impossible for them to cross because there cannot be two elevations at the exact same place.
i do not know
altitude
Contour line's measure elevation, there cannot be a space with two different elevations at the same time. For example, a hill can be 1,000 feet tall at the summit but not also 5 ft at its summit (unless you're in some parallel dimension). So no, they never cross.
Index contours
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.
A Topographic Map includes contour lines drawn to represent changes in elevation.The most important thing to remember is that CLOSE contour lines mean STEEP terrain and OPEN contour lines mean FLAT terrain.
altitude
Because contour lines make places of equal height.
Contour lines never cross because the elevations can't be two different numbers in one spot.
One contour can not cross another because a contour is one exact elevation; if it crossed another contour it would show that it is higher than the second contour on one side, but lower on the other side.
A contour line represents a certain vertical height above the the contour line shown drawn below. Contour lines are a means of representing 3D hills and mountains on a 2D flat paper. Maps should show the height between contour lines: 50 metres between contour lines is common.
Cross-hatch lines used in Architectural drawings are normally drawn at a 45 degree angle.
lines of equal elevation are called contour lines.

A contour lines are drawn on a map to show areas of the same height.

Contour lines are imaginary lines that join points of equal height. Therefore, say, a 300 metre height contour line can never meet a 400 metre height one.
