Which method is used to show the distribution of altitude, temperature, rainfall etc in a map?

  1. Choropleth method

  2. Isopleth method

  3. Dot method

  4. Chorochromatic maps
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Isopleth method is used to show the distribution of altitude, temperature, rainfall etc in a map. Isopleths are lines of equal value in the form of quantity, intensity and density. They are drown as contour lines at some selective interval. The spacing of lines express the rate of variation. If the  lines appear much apart, variation is gentle and when they are closely set, variation is sharp.

When a point on earth surface is accurately surveyed and shown with a triangle mark on the map, it is called ____________.

  1. bench mark

  2. relative height

  3. spot height

  4. triangulation point
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

When a point on earth surface is accurately surveyed and shown with a triangle mark on the map, it is called triangulation point.
In surveying, triangulation is the process of determining the location of a point by measuring only angles to it from known points at either end of a fixed baseline, rather than measuring distances to the point directly as in trilateration.

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.
