Air masses of different pressures and temperature move around the Earth. The cold air masses that form at the poles move toward the equator, while the warm air masses that form at the equator move toward the poles.
A "front" is the interface between two air masses of different temperature.
Pressure is the amount of air in one location which varies depending on temperature and other factors. You get high pressure when the air falls and low pressure when the air rises. However,there are different temperatures of air at lower levels of the atmosphere and where these air "masses" as they are called meet, you get a weather front. They do affect each other - low pressure systems (depressions) have different air masses entangled into it and therefore there are fronts in low pressures. Depressions also generally move around and between high pressures (anticyclones) and so high pressures do not move around as much as depressions. Pressure and fronts are often shown on the same weather image and the lines are called isobars which are lines of equal pressure. A front is where two air masses meet. Pressure is the amount of air.

parts of the world are closer to the sun causing warmer temperatures and the further away from the sun is when they are cooler.
Air masses have unequal or different temperatures because of the kind of material that compose the Earth's surface, angle of sun's rays, which is due to the shape of the Earth, and the length of daytime, which is due to the tilting of the earth's axis as it revolves around the sun.

could may also from when air masses of different temperatures collide.
Air masses or weather front is when two regions of air are colliding and they have different temperatures and pressures are similar.
Differences of atmospheric pressures or differences of temperatures of adjacent air masses.

A "front" is the interface between two air masses of different temperature.
An occluded weather front.
Such a boundary is called a front.
Air masses are two vast areas of air which have different temperatures and pressures but within the regions the temperatures and pressures are similar.
