What is the difference between climate and weather?

• A. Weather is short-term atmospheric conditions; climate is long-term patterns.
• B. Climate is short-term; Weather is long-term.
• C. Weather and climate are identical.
• D. Weather is constant, climate changes daily.

Answer: (A)

Weather refers to the current state and short-term changes in the atmosphere—temperature, humidity, precipitation, wind, and other conditions that can shift from hour to hour or day to day. Climate, on the other hand, covers the long-term behavior of those same variables, typically summarized as averages and patterns over months to decades. So a hot day is weather, while the overall tendency of a region to be warmer on average over many years describes its climate. Climate studies look at averages, variability, and extremes over long time scales and can reveal trends like warming or shifts in rainfall patterns. The other options mix up timescales, claim they’re identical, or suggest weather is constant, which doesn’t fit how these terms are used in practice.
