Final answer:
In terms of weather, high-pressure systems occur when the earth's surface atmospheric pressure is higher than the surrounding environment. These systems are associated with clear skies and dry weather.
Step-by-step explanation:
In terms of weather, high-pressure systems occur when the earth's surface atmospheric pressure is higher than the surrounding environment. These systems are associated with clear skies and dry weather. Anticyclones are examples of high-pressure systems where the air pressure is high. So the answer to your question is B) High pressure.
