Index Contours
Index contours are specially drawn contour lines that represent a specific round number of elevation, usually labeled with the exact value. They are useful for quickly identifying key elevation points on a topographic map.
Contour lines are typically labeled with their elevation, indicating the vertical distance above a reference point, such as sea level. This allows users to easily determine the elevation profile of the land or terrain represented on a map.
A high point on a topographic map is typically labeled with a spot elevation, which indicates the exact elevation of that point. This point is usually represented by a small circle with a number inside it, denoting the elevation. You can locate these high points by looking for the circles with numbers on the map.
A darker, thicker line on an elevation map typically represents a contour line, which connects points of equal elevation. These lines help illustrate the terrain's shape and slope, indicating how steep or flat an area is. The elevation value marked along these lines provides specific height information above sea level, aiding in understanding the landscape's topography.
A 1IN7 gradient refers to a slope where for every 7 units horizontally, the elevation increases or decreases by 1 unit vertically. This means that the slope is steep, with a relatively quick change in elevation over a short horizontal distance.
Contour maps.
I think it's an index contour, but I'm not sure.
Topographical lines
it is something i would know if i paid attention is science class. thats all i can say
just units

Called both Elevation Lines or Contour Lines
Sea level
Contour lines are typically labeled with their elevation, indicating the vertical distance above a reference point, such as sea level. This allows users to easily determine the elevation profile of the land or terrain represented on a map.
1324ft
Because it is a length and so must have units of length.
Mass is typically labeled in units of kilograms (kg) or grams (g).
