Contour lines represent points of equal elevation on a topographic map. If one contour line were to cross another, it would imply that the two elevations are the same at that point, which contradicts the purpose of contour lines to show gradual changes in elevation. Keeping contour lines from crossing helps maintain the accuracy and readability of the map.
The idea or concept of parallel lines is defined by Euclidean geometry as lines that never cross. So the regular answer is: No, they never cross, because then they will not be parallel according to Euclid.
But, I'm sure the questioner is not asking about Euclidean geometry but about reality.
In this sense some people will say: No, parallel never cross because there is no such a thing in real life. Parallel lines only exist in our mind.
But this answer is too simplistic. There is "reality" in our "ideal" concept of parallel lines. If reality was so disconnected from our geometric and logical constructs we would not be able to interact with the real world. We can walk, see and reason reality because we find circles, lines, logical constructs and 2 as the sum of 1 + 1, in the "real" world. Or at least, a very close approximation to that, though never "perfect" circles or lines.
Kant clearly demonstrated that these ideas are "hard coded" in our mind, not learned, because we need this idea "framework" to rationalize perception in the first place. There has never been a society where 1+1=3 and where parallel lines cross at say, 100 feet.
Questions like these are the beginning of modern philosophy, beginning with Plato who had not other option but to conclude that these ideas have an existence of their own in some kind of idea heaven. Of course the point is not whether this idea heaven exists, but to point out the real problems: Why do we have this constructs in our mind? What is the relationship to reality? Where do ideas come from?
So, in summary, yes, parallel lines in our mind never cross, and yes, they seem not to exist in reality. But there is a very real connection between the idea and the "real" thing, but since we can only "see" the "idea" we can not now in "reality".
The contour lines on a topography map are labeled with the elevation in round units. These lines connect points of equal elevation and help visualize the shape and elevation of the terrain.
I think its contour map, donno for sure though
A depression on a topographic map represents a lower elevation area relative to the surrounding terrain. It is typically shown with contour lines forming closed loops pointing towards lower elevation at the center, resembling a bowl or crater shape.
Another name for moving air is wind. Wind is the natural movement of air caused by differences in atmospheric pressure.
Topsoil is sometimes referred to as the A Horizon.
The contour interval would be 200 feet. This is calculated by dividing the total change in elevation by the number of contour lines.
no i dont think so
good luck to me i think
I do not think so , it is not mentioned in the bible.
I think you mean Tic-Tac-Toe.
One can never know what another is thinking.
We will never know because it has never been made yet!Another Answer:I think they meant machine ideas that were never invented, such as the Time Machine.
You know, when contour lines are closer together on a map, they indicate a steep slope. Just think of contour lines as the distance between each incline. The closer together the inclines, the steeper the hill.
I don't think it can
I am a greek too...I don't know if Justin Bieber come to greece...I think never!!!! :( Another Answer (By another person): I will never say never! He said he will go on WORLD Tour!! So... We are waiting him!!!
I think they have at some point or another
a terrorist is another mans freedom fighter.
