Background Paragraph: Weather is a set of all the phenomena occurring in a given atmospheric area at a given time. Most weather phenomena occur in the troposphere, just below the stratosphere. Weather refers, generally, to day-to-day temperature and precipitation activity, whereas climate is the term for the average atmospheric conditions over longer periods of time. When used without qualification, "weather" is understood to be the weather of Earth. 
Story: David was interested in climate change issues. He realized that to understand climate change issues he first needed to distinguish between the terms weather and climate. To that end, he labeled weather as term A. Then he labeled climate as term B. He found it easier to understand their differences in that way.
Is term A characterized by longer or shorter time period than term B? Is term B characterized by longer or shorter time period than term A? Which changes less frequently, term A or term B? Which changes more frequently, term A or term B? Which is characterized by longer time period, term A or term B? Which is characterized by shorter time period, term A or term B? Which may not use average atmospheric conditions, term A or term B? Which would use average atmospheric conditions, term A or term B? Would term A change less or more frequently than term B? Would term B change less or more frequently than term A?
