Final answer:
Subsiding air that diverges at the Earth's surface is associated with high-pressure systems in terms of weather.
Step-by-step explanation:
Subsiding air that diverges at the Earth's surface is associated with high-pressure systems in terms of weather. High-pressure systems occur when the atmospheric pressure at the Earth's surface is higher than the surrounding environment. In these systems, air sinks and diverges at the surface, leading to clear skies and calm weather.
