The statement that best describes a major difference in the quality of weather information contained in a daily forecast and a long-range forecast is:
Information contained in a daily forecast is more accurate than the information included in a long-range forecast.
Daily forecasts are typically based on more immediate and detailed data, resulting in greater accuracy for the short term, whereas long-range forecasts, which predict weather over a more extended period (usually beyond a week), tend to have less reliable accuracy due to the complexities and variability of weather patterns over time.
