Explanation:
V shaped contour line pointing downhill indicate a ridge line, while the ones pointing uphill indicate a water flow.
Explanation:
The contour lines are one of the basic and most important elements on the maps. While in general they are associated with representing the elevation, they actually tell much more about the topography of a place. In a typical contour line, it is relatively common that the V shape occurs at particular places.
The V shape can be pointed downhill or uphill. The ones that point downhill are indicators of a ridge line, thus they show us the ridge more easily, so we can orientate better and have better representation of the area. The ones that point uphill, on the other hand, are indicators that there is a water flow, or there was a water flow. The rivers and streams with their erosive power manage to create such shapes in the relief, if viewed from above. The opening on the V is from where the water flows down.
Some of the types of contour lines are:
- isopleths
- isohyets
- isobars
- isobaths
- isoterms
- isonephs

Answer: 12.8%
Explanation:
Urbanization rates show the the development of a nation because it shows how much of the population now live in cities which is synonymous with production and growth as opposed to rural areas which are associated with technological backwardness and agricultural overdependence.
The percentage of PNG's urban population can be calculated by the formula:
= Urban population / Total population * 100%
= 977,000 / 7,645,000 * 100%
= 12.8%
