A contour line is a drawing that is just an outline of an object, with no shading. I'm not sure if this answered your question, but it's a start.
parallel lines
Hachured contour lines are contour lines with ticks pointing downslope that indicate a depression on a topographic map.
The numbers of contour lines indicate altitude or elevation along that line.
If the contour lines on a topographic map have wide spaces in between and are further apart then the terrain is relatively flat. If the contour lines are close together then the terrain forms a steep slope.
Maps can show elevation with contour lines
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.

index contour lines have numbers contour lines dont
Contour lines are used in Topography to show the elevation of the land on a map. When looking at a map the contour lines look very similar to how a calm lake would appear.
parallel lines
contour lines all ways point up hill or up stream
The darker contour lines on map are called index contour lines. Numbers that indicate elevations are often written on these lines.
Most people are probably familiar with contour lines found on topographic maps, which show elevation. Contour lines can also show weather and climate data, such as temperatures and humidity. Less common, bathymetry (the depth of water bodies) can also be shown using contours.

Contour lines are lines that connect points of equal elevation. A topographical map is a map that uses contour lines to represent the elevation of land surfaces.
Contour lines connect points with the same what?
The closer the contour lines, the steeper is the slope.
