Detailed explanation-1: -Which correctly compares low-and high-pressure weather systems? A low-pressure system usually brings cool dry air and clear skies, while a high-pressure system brings clouds and precipitation.
Detailed explanation-2: -In a depression (low pressure), air is rising and blows in an anticlockwise direction around the low (in the northern hemisphere). As it rises and cools, water vapour condenses to form clouds and perhaps precipitation.
Detailed explanation-3: -Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), while high-pressure areas are associated with lighter winds and clear skies.
Detailed explanation-4: -Good weather is typically associated with high-pressure systems for this reason. Conversely, air flows into a low-pressure area to replace rising air. This air usually brings increasing cloudiness and precipitation. Thus, bad weather is commonly associated with areas of low pressure.
