What are the typical weather conditions associated with a low-pressure system?

Low-pressure systems are commonly associated with cloudy weather and precipitation due to the way they influence atmospheric conditions. In such systems, the atmospheric pressure is lower than that of the surrounding areas. This pressure differential causes air to move inward towards the center of the low-pressure area. As this air rises, it cools, which leads to condensation and cloud formation.

The upward motion of moist air in a low-pressure system not only creates clouds but also often results in various forms of precipitation, such as rain, snow, or thunderstorms, depending on the temperature and humidity of the air masses involved. Therefore, the presence of cloud cover and precipitation is a defining characteristic of low-pressure systems, making this option the correct answer.

Meanwhile, alternatives that mention clear skies, dry conditions, or high winds with little moisture fail to reflect the typical impacts of low-pressure systems and instead describe conditions more often associated with high-pressure systems. High-pressure areas promote clear, stable weather, while low-pressure systems are characterized by their unsettled and variable weather patterns.
