Question

‌‌A‌ ‌line‌ ‌on‌ ‌a‌ ‌map‌ ‌joining‌ ‌places‌ ‌of‌ ‌equal‌ ‌values‌ ‌is‌ ‌called‌ ‌an___________.‌ ‌
A.isotherms‌ ‌
B.‌ ‌isohyets‌ ‌ ‌
C.‌ ‌isobars‌ ‌
D.‌ ‌isolines‌ ‌

Answer 1

Hint: The lines on a map are called contour lines. They determine the exact locations of places.

Complete Answer: Looking at the options above :

Option a: Isotherms are lines of constant or equal temperature. They are mainly used on weather maps by meteorologists to provide a large scale picture of temperatures across the U.S. This option is incorrect.

Option b: Isohyets are lines drawn on a map which connect places having equal rainfall. This option is incorrect.

Option c: Isobars are lines drawn on maps connecting points having the same atmospheric pressure at a given time or on average over a given period. This option is incorrect.

Option d: A line on a map joining places of equal values is called an isoline. Isolines are used to represent elevation on a map by connecting points of equal elevation.This option is correct.

So, the correct answer is option D.

Note:
-Geographers always use isolines to enable them to map the distribution of things.
- Contour lines, for example, show relief and combine points on the map that have the same size or height.
- Isobars are developed from average sea-level pressure reports and are provided in millibars.
