What phenomenon can occur due to changes in temperature and pressure in the atmosphere?

Weather is the correct answer because it refers specifically to the short-term atmospheric conditions in a specific place at a particular time. Changes in temperature and pressure are fundamental factors that influence weather patterns. For example, as air warms, it rises, leading to lower pressure, which can create winds and precipitation as the air cools and condenses. This immediate interplay between temperature and pressure results in phenomena such as rain, thunderstorms, snow, and clear days.

In contrast, climate refers to the long-term average of weather patterns in a particular area over an extended period, typically 30 years or more. Seasons relate to the predictable changes in weather patterns that occur at certain times of the year due to Earth's axial tilt and orbit around the sun, affecting climate rather than daily weather phenomena. Forecasting involves predicting weather events based on data analysis and models but does not describe the phenomena that result from temperature and pressure changes directly.
