D Correct answer
Explanation

Distribution in maps is nothing but the distribution of variables like temperature, rainfall and population which can be shown in maps. Distributions can be shown in the following ways:

  • Dot Method
  • Choropleth Method
  • Isopleth Method

How the distribution through dot method are shown on maps?

  1. Size of dots

  2. Density of the variable

  3. Scale of the map

  4. All of above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

To show distribution through dot method, we need to consider the size of the dot, the density of the variable and the scale of the map. The number of the dots to be given for the value of variable in each sub-administrative unit need to be decided first.

Following precautions should be taken while using dot method for maps:-

  • The size of a dot should be uniform.
  • The distribution of physiography, water sources, transport system, etc. of a region should be considered while placing dots on a map.
  • While showing population distribution, rural population is shown by dots and circles are used to show urban population.

What attributes are shown on a map using isolines?

  1. Physical attributes

  2. Chemical attributes

  3. Man made attributes

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Physical attributes are shown on map using isolines.
Isolines, also referred to as contour lines, can be used to represent elevation on a map by connecting points of equal elevation, for instance. As with all isolines, when contour lines lie close together, they represent a steep slope; lines far apart represent a gradual slope.

Which types of maps shows the various geographical variables by shades or tints of various colours?

  1. Isopleth maps

  2. Topographical map

  3. Choropleth map

  4. Dot method
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
A choropleth map is a thematic map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map, such as population density or per-capita income.

Choropleth maps provide an easy way to visualize how a measurement varies across a geographic area or show the level of variability within a region. A heat map is similar but does not use geographic boundaries.
