Final answer:
Weather describes the short-term atmospheric conditions such as temperature and precipitation, while climate refers to long-term patterns in a specific area. Climate change involves significant and lasting changes in weather patterns, which can impact our lives and the environment.
Step-by-step explanation:
Weather is the term used to describe the conditions of the atmosphere over a short period of time, such as temperature, humidity, precipitation, cloudiness, visibility, and wind. In contrast, climate refers to the long-term average weather patterns that occur within a particular region over periods of decades to centuries. For instance, while the climate can give us an expectation of whether a particular season will be wet or dry, hot or cold, the weather is what actually occurs on a given day and can be unpredictable in the short term. Climate change is a significant alteration in the average weather conditions, like global warming, which can have severe effects on living conditions.
