Definition of Weather
The correct answer to the given question is option B: "State of the atmosphere over an area at any point of time." This option accurately defines weather and distinguishes it from the other options.
Explanation
1. Option A: Envelope of air surrounding earth
This statement describes the atmosphere, which is a layer of gases that surrounds the Earth. While the atmosphere is relevant to weather, it does not define weather itself. Weather refers to the state of the atmosphere, including various meteorological elements, rather than simply the envelope of air.
2. Option C: Atmospheric conditions over a large area for a long period of time
This statement describes climate, not weather. Climate refers to the long-term average weather conditions over a large region, typically spanning several decades. Weather, on the other hand, refers to the current or short-term state of the atmosphere at any given moment.
3. Option D: Generalized monthly atmospheric conditions
This statement describes climatology, which involves the study of climate based on long-term averages and patterns. It focuses on generalized monthly atmospheric conditions rather than the instantaneous state of the atmosphere, which is the primary concern of weather.
Conclusion
In summary, weather is defined as the state of the atmosphere over an area at any point in time. It refers to the current conditions, including temperature, humidity, precipitation, wind speed, and atmospheric pressure. While options A, C, and D are related to the atmosphere, climate, and climatology, respectively, option B accurately defines weather itself.
