what happens when a warm air mass moves over a cold air mass?
it leads to thunderstorms and heavy rain
it leads to cloudy skies and gentle rain
it leads to long periods of cloudy weather
it leads to a mix of weather like cloudy skies, rain, and storms

Explanation:

When a warm air mass moves over a cold air mass, it forms a warm front. Warm air is less dense than cold air, so it rises slowly over the cold air. As it rises, it cools, and the moisture in it condenses. This process typically leads to cloudy skies and gentle rain rather than sudden, intense weather like thunderstorms (which are more associated with cold fronts where cold air rapidly pushes under warm air). Long - period cloudy weather without rain is more characteristic of stationary fronts, and a mix of weather like storms along with clouds and rain is more complex and not the typical result of a simple warm - front (warm air over cold air) situation.

Answer:

It leads to cloudy skies and gentle rain.
