Q:

# Why can't contour lines ever cross each other?

A:

Contour lines do not cross each other because of the variance in elevation between the lines. However, an instance where two contour lines intersect occurs when the elevations are simultaneously crossed at an identical point through a vertical ledge.

Contour lines are irregularly shaped patterns that typically form waves, concentric rings, loops or other oscillations that identify a meteorological quantity on a contour map. An "isobar" is associated with pressure, an "isotherm" with temperature, an "isotach" with the speed of wind and an "isodrosotherm" with dew point. The value of each atmospheric quantity is uniform along a contour line, hence, no two contour lines intersect.

Parallel lines are defined as lines that are equal distance apart and never touch. Being an equal distance apart is also known as equidistant. Parallel lines always point in the same direction.

Parallel lines are lines along the same plane that never intersect, even though they are of infinite length. If you are working on a construction project, it is important to make sure that segments that are supposed to be parallel actually are. To prove that two lines are parallel, you need a square or a protractor and a straight edge.

Intersecting lines are two lines that meet or cross. The exact place of intersection between two lines is called the "point" or "point of intersection" in geometry.
