Answer:
Topographic maps have contour lines that connect points of identical elevation above sea level. Contour lines run next to each other. Adjacent contour lines are separated by a constant difference in elevation, usually noted on the map. Topographic maps have a horizontal scale to indicate horizontal distances.
To the west the Mediterranean Sea is connected to the Atlantic Ocean by the Strait of Gibraltar, which at its narrowest point is only 8 miles (13 km)
Converging plate boundaries. continent to continent plate boundary converging if you want to be more specific.
