  1. One

  2. Two

  3. Three

  4. Four

Show answer
Correct Option: C
Explanation:

Distribution in maps is nothing but the distribution of variables like temperature, rainfall and population which can be shown in maps. Distributional maps are of three type:-

  • 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

Show answer
Correct Option: D
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.

Which data are used to prepare dot maps?

  1. Statistical data

  2. Geographical data

  3. Normal data

  4. All of above

Show answer
Correct Option: A
Explanation:

A dot maps is prepared using statistical data. While preparing dot maps, only data gathered through counting is used. The way a variable is distributed throughout the region, the dots are used to show its distribution on the map.

Which of the following precautions should be taken while using dot method for map?

geography understanding maps maps - our companions maps and its study contour maps and landforms

  1. The size of a dot should be uniform

  2. The distribution of physiography, water sources, transport system, etc. of a region should be considered while placing dots on a map.

  3. While showing population distribution, rural population is shown by dots and circles are used to show urban population.

  4. All of above

Show answer
Correct Option: D
Explanation:

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?

geography understanding maps maps - our companions maps and its study contour maps and landforms

  1. Physical attributes

  2. Chemical attributes

  3. Man made attributes

  4. None of the above

Show answer
Correct Option: A
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.

The maps which are prepared with some special themes are called ___________.

  1. political maps

  2. physical maps

  3. thematic maps

  4. topographical maps

Show answer
Correct Option: C
Explanation:

A thematic map is a map that focuses on a specific theme or subject area such as physical phenomena like temperature variation, rainfall distribution and population density in an area.

In a dot method map, while showing population distribution, urban population is shown by ___________.

  1. dot

  2. shades

  3. lines

  4. circles

Show answer
Correct Option: D

Which of the following steps are used to prepare Isopleth maps?

geography understanding maps maps - our companions maps and its study contour maps and landforms

  1. By considering the highest and lowest values of the variable

  2. Class interval should be decided

  3. Lines are drawn for the decided intervals, location with the same value are joined by a line

  4. All of above

Show answer
Correct Option: D
Explanation:

Following steps are used to prepare isopleth maps:-

  • By considering the highest and lowest values of the variable.
  • The class interval is decided to draw the isopleths maps which in turn decides the difference between the lines.
  • Lines are drawn for the decided intervals, location with the same value are joined by a line

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

geography understanding maps maps - our companions maps and its study contour maps and landforms

  1. Isopleth maps

  2. Topographical map

  3. Choropleth map

  4. Dot method

Show answer
Correct Option: C
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.

A line on a map joining places of equal temperature is called an _____________.

geography understanding maps maps - our companions maps and its study contour maps and landforms

  1. isohytes

  2. isobars

  3. isotherms

  4. isohalines

Show answer
Correct Option: C
Explanation:

Lines joining places of equal temperature are called as Isotherms.

Isopleth - General term for a line connecting points of equal value of some quantity. Isobars, isotherms, etc. all are examples of isopleths. Isotach - A line connecting points of equal wind speed. Isotherm - A line connecting points of equal temperature.
