Question

Give reasons why following sentences

are right or wrong:

(1) The main aim of distributional

maps is to show location.

(2) In choropleth maps, only one

value is assigned to the

sub-administrative unit.

(3) In choropleth maps, colours/tints

do not change according to the

values of the variables.

(4) Choropleth maps are used to show

altitudes.

(5) Isopleth maps are used to show

population distribution.

(6) In dot method, every dot should

have an appropriate scale.

(7) Isopleth maps are not made using

isolines.​

Answer 1

Explanation:

(1) ANS :

The distribution of map shows the temperature, climate, rainfall and others.

we can easily check all the climatic conditions of different regions.

(2) ANS:

No, the different sub-administrative unit is assigned in the choropleth maps. ... The areas are shared in proportion to the statistical variable measurement in the map. The choropleth map is filled with the uniform pattern and color.

(3)ANS:

It is wrong statement.

in chloroplast map the data regarding various of graphical variables are shown by shading 18th of various colours to wants of Administration unit in a region the smallest and the largest values are taken into consideration as after the 5-7 classes are made which class is assigned 18th of the same colour or a black and white pattern.

(4)ANS:

yes, An isarithmic map uses isolines, lines that connect equal values, to illustrate continuous data such as elevation, air pressure, and precipitation. Topographic maps use contour lines to show elevation. Explanation: because the choropleth shows only distribution of population , colours , pattern this is choropleth.

(5)ANS:

Distributional maps refer to those maps which indicate the distribution of a particular feature in a given area. These features can range from population distribution in districts/talukas to wheat production in different farms in a single village.

(6)ANS:

Spatial distribution and abundance of the phenomena of a place actually decides a dot size. ... The size and number of dots can provide a different impression about the spatial distribution of the place on the map to the reader. Thus every dot on the map must have an appropriate scale.

(7)ANS:

Isopleth maps are drawn using equal value lines on them. Values on one side of the line drawn are more than the isoline value, while those on the other side are lower. ... Thus, the reason why isolines are not used to draw the lines is that the values on either side are not the same.
