Answer:
Step-by-step explanation:
A front is a strip in which two air masses of different temperatures are separated. In other words, a front is a transition zone between two air masses of different nature.
The warm front occurs when the hot air mass advances to replace the cold air. That is, it is the one that marks the separation between two air masses, between which there is no displacement of one respect to the other. Usually, when a warm front advances, it leaves a trace of rising temperatures and ambient humidity. Increasing these variables causes the atmospheric pressure to fall, so there will be some not very strong rains.
The stationary front is the one that marks the separation between two air masses, between which there is no displacement of one from the other. In other words, it is a boundary that exists between two air masses. Each mass of air is as strong as the other, so that none can displace or replace the other. This produces long periods of cloudiness and mild rainfall. Often, the weather is cloudy along a still front and rain or snow can fall, especially if the front is in an area of low atmospheric pressure.
