Fictional temperature isolines. Original fictional resource; not an official map or real dataset.Resource description
Equal-value lines: 16°C, 18°C, 20°C. P lies between 18°C and 20°C.
Use the resource carefully
State the unit and the part of the resource you used. A pattern in a fictional dataset is evidence for that exercise; it does not establish a fact about a real place.
Check whether an explanation is supported by the data or needs additional geographical knowledge. For statistical tasks, a calculated result does not establish causation or significance by itself.
