The boundary between two air masses is called a front.
The point where these two air masses meet is called a front.
The border between stalled air masses is called a stationary front. This boundary separates two air masses with different characteristics, such as temperature and humidity, leading to prolonged periods of unsettled weather in the region.

The location where two different air masses meet is called a front.
A strip of water between two land masses is called a strait.
The space between two air masses is referred to as a front. Fronts are categorized by which kind of air mass, warm or cold, is replacing the other. +++ IT's not really a "space" between the air masses - that would be a vacuum! Rather, it's a somewhat diffuse boundary.
It is called the border. There are border crossing set up on most of them to control who comes in or out of the country.
Gravitational force is a non-contact force that acts between two masses.
The border between a warm air mass and a cold air mass is called a front. There are different types of fronts depending on how the air masses interact, such as cold fronts, warm fronts, stationary fronts, and occluded fronts. This clash of different air masses can lead to various weather phenomena.
The force of attraction between any two masses anywhere in the universe is called gravity.
