Question

12 what type of weather does a low pressure system cause?

Explanation:

In meteorology (a subfield of Natural Science, specifically Physics or Atmospheric Science), low - pressure systems are associated with rising air. As air rises, it cools and condenses, leading to the formation of clouds and precipitation. So, low - pressure systems typically cause cloudy, rainy (or stormy) weather. For example, cyclones are low - pressure systems that bring heavy rains and strong winds.

Answer:

A low - pressure system typically causes cloudy, rainy (or stormy) weather (such as precipitation, cloudiness, and often windy conditions).
