A saddle
A topographic feature that is a dip or low point between two areas of higher ground is called a "valley." Valleys can be formed by various geological processes, including erosion by rivers or glaciers. They often serve as natural corridors for water flow and can be rich in biodiversity and agricultural potential.
A saddle
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.
No, not all topographic maps have a 0 meter contour line as a starting point. The starting point for the contour lines on a map is typically determined by the elevation of the area being mapped. In some cases, the starting point may be a higher or lower elevation depending on the region being mapped.

Point by point organization
To determine the elevation of point A on the topographic map, look for the contour lines closest to that point. The elevation of point A will typically be indicated by the nearest contour line, with the value increasing or decreasing based on the direction of the contour lines. If point A is between two contour lines, estimate its elevation based on its relative position to those lines. Without the specific map, I can't provide an exact elevation, but this method will guide you in finding it.

A benchmark is just a point on the map, so that you can see where on the map you are.
