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 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.
The main topographic map rules include contour lines never crossing, contour lines close together represent steep terrain, contour lines spread out represent flat terrain, and elevation is indicated by the contour lines.
The contour lines on a 500 mb chart are lines of constant pressure at 500 millibars in the atmosphere. These lines connect points of equal pressure at that specific level, providing a visual representation of the pressure patterns in the upper atmosphere.
If the contour interval is not given, find two reference (labeled) contour lines and find the number of lines between them, excluding the reference lines themselves. Then the interval can be found using the following formula: |(Difference between elevation of reference lines)| /(Number of contour lines between reference lines +1) = Contour interval For example, if you find two reference lines labeled 150m and 250m and there is one contour line between them, then |150m-250m|/(1+1)=100m/2=50m The contour interval of that map is 50 meters.
Index contours are specially drawn contour lines that represent a specific round number of elevation, usually labeled with the exact value. They are useful for quickly identifying key elevation points on a topographic map.
Contour lines represent constant elevations on a map. If they were to cross, it would imply that a single point on the map has two different elevations, which is physically impossible. Crossing contour lines would lead to inaccuracies in interpreting the terrain and understanding the topography represented on the map.
Because contour lines make places of equal height.

Contour lines connect points of equal height, and show grades of hills, the closer together the lines the steeper the grade. The map legend should tell you the difference in elevation between lines, this could be in feet or meters
Cross-hatch lines used in Architectural drawings are normally drawn at a 45 degree angle.
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.
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.
