Question

How do meteorologists use isotherms and isobars?

A. To identity high- and low-pressure systems
B. To identify areas of high and low water vapor
C. To differentiate between seasons
D. To provide estimates for the amount of direct sunlight received

Answer 1

A. To identity high- and low-pressure systems

Step-by-step explanation:

Isobars are similar to the level lines on a topographic map, showing areas of similar pressure, they are also drawn in circles to represent the areas of similar air pressure over a geographical map.

Isotherms are usually displayed in color showing areas over a map that have the same temperature or are covered by a similar temperature system (heat or cold front for example).

Both are used in electronic media mostly (although in print in newspapers too), over a geographic map to position the systems.
