Question

Which of the following statement(s) is(are) true about isopleth maps?

• A. They are extensively used in meteorology.
• B. They show data in the second dimension.
• C. The isopleth interval is the difference in values between two adjacent isopleths.
• D. Isopleths never cross or divide and always form enclosed circles.

Answer 1

Answer: (A), (C), (D)

The correct options are
A They are extensively used in meteorology.
C The isopleth interval is the difference in values between two adjacent isopleths.
D Isopleths never cross or divide and always form enclosed circles.

An isopleth map generalises and simplifies data with a continuous distribution. They are used extensively in operational meteorology. They are more common for mapping surface elevations, amounts of precipitation, atmospheric pressure, and several other geographical variables. Isopleths show data as a third dimension. The isopleth interval is the difference in value between two adjacent isopleths. The values of the isopleths drawn on the map are multiples of the interval. Isopleths never cross or divide and always form enclosed circles.
