Question

What is an isogram on a map?
A. A line representing the difference in elevation in two areas.
B. A point representing the unique value of quality in an area
C. An area representing a range of temperatures
D. A line representing an equal value of a given quantity

Answer 1

Hint: A map is a symbolic representation, typically drawn on a flat surface, of selected characteristics of a location. In a clear, visual way, maps present knowledge about the globe.
By showing the sizes and shapes of nations, positions of features, and distances between places, they teach about the world.
Complete answer:
A. Isolines are lines drawn on a map connecting the same value data points. Geographers generally use them. For instance, contour lines display relief and connection points that have the same height on the map.
B. Isoline representation is the most commonly used method of visualizing comprehensively occurring quantitative phenomena whose values differ continuously in space. Therefore, they are considered continuous. Temperature, air pressure, precipitation heights, or ground elevations are examples of such continuums.
C. A line that represents a constant or equivalent value of a certain quantity on a particular surface, as on a map. A line on a chart, such as a contour line, connects points that have the same value for a certain quantity.
D. Isograms are imaginary lines that link a quantity with places of equal value. Isograms may be of various forms, such as:
Isobar: isogram of equal pressure connecting points.
Isotherms: an isogram that links points with equal temperatures.
Isohel: isogram of equal sunshine linking points.
E. An isogram on a map is a line drawn that connects equal-value points.

Hence, Option D. A line representing an equal value of a given quantity is the correct answer.

Note: A thematic map is one that is constructed in relation to a geographic region to highlight a particular theme. In order to indicate points with the same magnitude, an isoline map utilizes continuous lines and is widely used for weather or topography.
