Weather changes quickly while climate is what?

Correct answer: Long-term average pattern

Direct answer: Option B is correct. Climate is the long-term average pattern of weather in a place. Weather describes short-term atmospheric conditions, such as today’s temperature, cloud, wind, or rain, and it can change within hours or days. Climate is understood by observing weather over a much longer period and identifying usual patterns, including average temperature, rainfall, seasons, and variation. Step by step: weather is an individual or short period condition; many observations are collected over years; the repeated average and general pattern are studied; that long-term pattern is called climate. Option B correctly gives this meaning. Option A is wrong because a very short-time event describes weather, not climate. Option C is wrong because climate is not limited to one hour. Option D is wrong because climate includes all seasons and is not limited to nighttime. Climate does not mean that every day has identical weather; it describes the usual long-term behaviour and range. Memory cue: weather is what is happening now; climate is what usually happens over a long time.
