What is true about weather?

Weather refers to the short-term atmospheric conditions in a specific area at a given time. This includes variations in factors such as temperature, humidity, precipitation, wind speed, and atmospheric pressure. The defining feature of weather is its variability; it can change from hour to hour and day to day, influenced by various factors like geographical location and seasonal patterns.

The option stating that weather changes over short periods aligns perfectly with this definition, as it captures the transient nature of weather phenomena. In contrast, climate encompasses the average atmospheric conditions over longer periods—typically 30 years or more—making those related choices incorrect. Additionally, the assertion that weather is static contradicts its dynamic characteristics, and equating weather with climate overlooks the fundamental differences between the two concepts.
