Final answer:
Low-pressure systems result in weather events like rain or snow due to rising moist air that condenses into clouds. Two types of core lows are cyclones (extratropical lows) and hurricanes (tropical lows), leading to various weather conditions, from thunderstorms to storm surges.
Step-by-step explanation:
Low-pressure systems are weather phenomena where the atmospheric pressure at the surface of the Earth is lower than its surrounding environment. This situation leads to the ascent and condensation of moist air, resulting in cloud formation and precipitation. There are two primary types of core lows associated with these systems: cyclones (also known as extratropical lows) and hurricanes (also called tropical lows). Cyclones are usually associated with cooler weather fronts and can lead to diverse weather patterns including rain, snow, and thunderstorms. In contrast, hurricanes are associated with warm, tropical oceans and can lead to strong winds, heavy rainfall, and sometimes devastating storm surges.
