Which map depicts rainfall distribution, represented by dots and isopleths?

• A. Statistical Map
• B. Isopleths
• C. Isopach Map
• D. Planimetric Map

Answer: (A)

Rainfall distribution is best shown on a statistical map, which uses symbols like dots to indicate how much rain falls and can include isopleth lines to connect areas with equal rainfall. The dots give a sense of the density or amount, while the isopleths reveal gradients and regions where rainfall is similar, letting you read both the level and the spatial pattern at a glance. An isopleth map would focus on contour lines alone without the dot symbolism; an isopach map shows thickness of a layer rather than rainfall; a planimetric map emphasizes the positions of features rather than conveying data values.
