Which statement best describes low-pressure systems?

Low-pressure systems are characterized by rising air, which often leads to cloud formation and precipitation. As the air ascends, it cools, leading to the development of clouds and potentially stormy or rainy weather. This rising air creates a situation where the temperature can be more uniform throughout the day, especially compared to high-pressure systems, which tend to clear the skies and allow for greater temperature fluctuations due to the enhanced solar heating during the day and cooling at night.

The phenomenon associated with low-pressure systems leads to changes in weather patterns that don't align with clear or sunny conditions, nor do they contribute to significant increases in temperature or dry weather. Instead, they are often connected to overcast skies and varying weather conditions, thus minimizing temperature changes throughout the day when compared with the temperature swings seen under high-pressure systems.
