Contour lines never cross because the elevations can't be two different numbers in one spot.
It is unlikely because you cant have 2 elevations at the same point
the contour interval
Two lines cross or intersect at a point.
Intersecting lines are two lines that cross in a coordinate plane. So, yes, intersecting lines cross.
A line cross
Because contour lines make places of equal height.
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.

The difference in elevation between two contour lines that are side by side is the contour interval. The contour interval is the vertical distance between two adjacent contour lines on a topographic map.
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.
Each contour line represents a certain elevation, and the difference in elevation between any two adjacent countour lines is constant. So, for example, if in the map area there were a cone-shaped feature, like a volcano, the shape would be shown as a circle in a circle in a circle in a circle (and so on). The more contour lines you cross along a path, the steeper the climb, and the fewer contour lines you cross on the path, the more level it is.

Contour interval.
Contour lines don't really "cross" if we consider them strictly. But they can "merge" at a point where there is an abrupt change in elevation, as a cliff. Let's look at things a bit more closely. If we map a hill with one side cut straight down by something like a quarry or the action of a river, we'd see contour lines on a map coming together to "merge" along the face of the cliff. There are "multiple elevations" represented by the face of the cliff, and two or more lines might become one line along what is the cliff face on our map.
