The correct option is B. The land and sea temperatures were greater than usual overall.
The diagram is a heat map to show the fluctuations in temperature.
What are heat maps?
- A heat map is a type of data visualization that displays a phenomenon's size in two dimensions using colour.
- The reader will receive clear visual clues about how the occurrence is clustered or fluctuates over space from the fluctuation in colour, which may be by hue or intensity.
- The cluster heat map and the spatial heat map are two fundamentally distinct types of heat maps.
- In a cluster heat map, magnitudes are arranged into a matrix of fixed cell size, where the rows and columns represent discrete phenomena and categories.
- The sorting of the rows and columns is deliberate and somewhat arbitrary, with the intention of suggesting clusters or depicting them as they are identified through statistical analysis.
According to the diagram, both land and sea temperatures were higher than usual.
