The statement of the condition that the boundary, which is formed when two air masses with different temperatures or humidity levels meet, instead of immediately mixing or blending, is TRUE.
A front is mainly of four types, which are -
- Cold
- Warm
- Occluded
- Stationery
<h3>What are boundary fronts?</h3>
The physical properties of air masses with different temperatures do not mix or blend because they are a type of stationary front, which results in mere movement of the masses.
Such fronts can only be mixed if the masses are of two similar temperature groups, but is not practically possible and hence they create a boundary line.
Hence, it can be concluded that the boundary or line formed by two different air masses is called front is TRUE.
