A "front" is the interface between two air masses of different temperature.
contact
A divergent boundry will form beetween them.
both warm and cold front
Divide
The density. Refraction occurs at the boundary between two media of differing densities, such as air and water.
The direction of light propagation can be changed at the boundary of two media having different densities. This property is called refraction, and is illustrated in the following figure for the boundary between air and water.

Anything between zero and millions of tons. Different materials have different densities, i.e., different amounts of mass per cubic centimeter.Anything between zero and millions of tons.

air masses with different characteristics such as temperature and humidity do not usually mix. so when two different air masses meet a boundary forms between them.
90 degrees
Of course, the densities are different.
The sun!
Such a boundary is called a front.
The oil will change densities based on the temperature. When it gets too hot, it will get less dense and visa versa.
boundary fill fills boundary with one color and flood fill fills boundary with different color.
The densities between lemon and lime are quite different. When you put a lime in a bucket of water, it will sink while a lemon will easily float in the same water. A lime has a higher density than a lemon.
