Which of the following is used to refer to the height of a point on the ground above the mean sea level?

  1. Triangulated height

  2. Spot height

  3. Relative height

  4. Bench mark

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A spot height is an exact point on a map with an elevation recorded beside it that represents its height above a given datum. In the UK this is the Ordnance Datum. Unlike a bench-mark, which is marked by a disc or plate, there is no official indication of a spot height on the ground although, in open country, spot heights may sometimes be marked by cairns. In geoscience, it can be used for showing elevations on a map, alongside contours, benchmarks, etc.

The triangulated height is generally used to indicate _____________.

  1. plateaus

  2. ridges

  3. mountain peak

  4. plains

C Correct answer
Explanation

The triangulated height is generally used to indicate mountain peak.

Triangulation pillars are used by map makers. They are real concrete pillars that are placed at particular places which are usually the tops of hills or mountains.

A spot height is an exact point on a map with an elevation recorded beside it that represents its height above a given datum. In the UK this is the Ordnance Datum. Unlike a bench-mark, which is marked by a disc or plate, there is no official indication of a spot height on the ground although, in open country, spot heights may sometimes be marked by cairns.

In steep slopes the difference between maximum and minimum height is represented by letter 'r' which indicates ____________.

  1. bench mark

  2. spot height

  3. triangulated height

  4. relative height

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In steep slopes the difference between maximum and minimum height is represented by letter 'r' which indicates relative height.

Relative Height is a concept used in visual and artistic perspective where distant objects are seen or portrayed as being smaller and higher in relation to items that are closer.

Why Contour lines are useful ?

  1. Show the shape of the land surface (topography) on a map.

  2. Joins points of equal elevation , above a given level.

  3. Both A and B.

  4. None of the above.

C Correct answer
Explanation

Contour lines are useful because they allow us to show the shape of the land surface (topography) on a map. The two diagrams below illustrate the same island. The diagram on the left is a view from the side (cross profile view)such as you would see from a ship offshore.

Define the characteristics of Contours _________________.

  1. Contour lines must close , not necessarily in the limits of the plan.

  2. Widely spaced contour indicates flat surface.

  3. Closely spaced contour indicates steep slope ground.

  4. All of the above.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The characteristics of contour lines which help in plotting or reading a contour map are as follows;
1) Contour lines must close, not necessarily in the limits of the plan.
2) The horizontal distance between any two contour lines indicates the amount of slope and varies inversely on the amount of slope.
3) Widely spaced contour indicates a flat surface.
4) Closely spaced contour indicates a steep slope ground.

What are the characteristics of Contour lines ?

  1. Steep slopes.

  2. Gentle slopes

  3. Summits.

  4. All of the above.

D Correct answer
Explanation

Contour lines are used to represent various landforms, including steep slopes (lines close together), gentle slopes (lines far apart), and summits (closed concentric circles). Therefore, all these features are characterized by contour lines.
