Concept:Weather is the short-term state of the lower atmosphere at a specific place.
Explanation:The lower atmosphere changes from hour to hour and day to day.
Conditions such as sunshine, rain, wind, or cloud cover describe the weather.
Weather is always brief and can change quickly, for example, a sunny morning may become rainy by noon.
Climate, on the other hand, describes average atmospheric conditions over a long period, usually 30 years or more.
Because the question refers to a "short period," the correct description is weather.
Answer:B. weather
