A primary reason for drawing isotherms on a map of temperature values is to allow: A) a visualization of temperature distribution. B) determination of temperature ranges. C) calculation of mean values. D) elimination of extreme values.

Option C) calculation of mean values.

Explanation:

Places with the same temperature are joined together by means of lines called isotherms. These are lines that have been drawn to join places with the same temperature. Therefore, to make the most of the information, it is necessary to have the lines with the same same temperature throughout. In order to achieve this, the lines will have the same temperature distribution throughout the region connected by the lines. This enables the places to be linked by the same thermal distribution.

a visualization of temperature distribution.

Explanation: Isotherms can be defined as a line of equal or constant temperature on a graph or chart, such as a weather map.

Isotherms are commonly used in meteorology to show the distribution of temperature at the Earth’s surface or on a chart indicating constant level or constant pressure.
