They're all wrong, redo them.
Your answers are mostly correct! Here are the correct answers for the questions you got wrong:
1. A forecast indicates a dew point temperature equal to the air temperature. What does this information imply? - The correct answer is "Relative humidity is 100%, and it may rain." This is because when the dew point temperature is equal to the air temperature, the air is saturated with water vapor and there is a high chance of rain.
4. Which air mass would form over warm water? - The correct answer is "maritime tropical." Air masses form when they move over a large body of water, and maritime tropical air masses form over warm water.
7. Which weather-based data would be most helpful for a meteorologist to track in order to most accurately predict changes in weather? - The correct answer is "levels of precipitation and types of clouds." This is because precipitation and cloud types can provide valuable information about the weather conditions and can help meteorologists make more accurate forecasts.
8. Which statement best describes a major difference in the quality of weather information contained in a daily forecast and a long-range forecast? - The correct answer is "Information contained in a daily forecast is more general than the information included in a long-range forecast." Daily forecasts provide more specific and detailed information about the weather conditions for the next few days, while long-range forecasts are more general and cover a longer period of time.
Great job overall!
