Why is it impossible that two contour lines will cross on the maps you have drawn?
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.
What else can I help you with?
WHY don and rsquot DO you think contour line never crosses another contour line?
Contour lines represent areas of equal elevation on a map, meaning that if two lines were to cross, it would indicate two different elevations at the same point, which is impossible. This would create a contradiction in the representation of the terrain. Additionally, crossing contour lines would imply a sudden change in elevation, which is not consistent with the gradual change that contour lines illustrate. Thus, to maintain clarity and accuracy in depicting the landscape, contour lines never cross.
Why contour line never cross?
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.
What are the main topographic map rules?
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 drawn on a 500 mb chart are lines of constant?
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.
What are the factors effecting contour intervals?
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.
Why should contour lines never cross?
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.

Why is is unlikely that two contour lines will cross?
Because contour lines make places of equal height.

How are contour lines drawn on maps?
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
How do contour lines help you visualize a feature earths solid surface?
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.
What angle are ' cross-hatch' lines normally drawn?
Cross-hatch lines used in Architectural drawings are normally drawn at a 45 degree angle.
How do contour lines help you visualize a feature of Earth solid surface?
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.
Line drawn on a topographic map to join points of equal elevation?
lines of equal elevation are called contour lines.
What are the main topographic map rules?
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.
What is a specially drawn contour lines used to represent a round number of feet or meters?
gelatin
What is a con tour line?
A contour lines are drawn on a map to show areas of the same height.
