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.

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.
