Which option shows correct use of data in climate study?

Answer and explanation

Correct answer: Using daily data over many years to find averages and trends

Answer: A, because climate is understood from observations collected over a long period, not from one short observation. Weather describes the condition of the atmosphere at a particular time, whereas climate refers to the usual pattern of weather over many years. Researchers therefore record measurements such as temperature and rainfall regularly, organise the observations, calculate averages, and examine changes or trends. Option A correctly describes this evidence-based method. B is wrong because one temperature reading represents only one moment and cannot describe a long-term pattern. C is wrong because climate conclusions require observations or reliable records. D is wrong because map colours are only a way of displaying data; colours alone cannot replace the measurements and their analysis. Memory cue: weather is a short observation; climate needs long records and averages.
