There is little difference between controlled and modified atmospheres. They both refer to atmospheres where the proportions of the normal gaseous/vapor components oxygen, nitrogen, carbon dioxide and water vapor, are modified to achieve some storage/packaging goal. This is commonly lowering the oxygen and/or increasing the carbon dioxide. All such atmospheres are modified atmospheres, they become controlled atmospheres when an attempt is made to regulate the composition of one or more of component gases.

A packaging gas is any gas used to provide a modified atmosphere for a product in storage.
Its where the atmosphere in which a product is tored/kept is changed, i.e. oxygen is removed from the air of pre-prepared salads and other gases are added, this makes it MAP
Its the part of our environment that is modified by humans. Its one of the 5 spheres of the earth: atmosphere, geosphere, biosphere, hydrosphere and anthrosphere.
Reference: Food Packaging, Principles and Practice by Gordon L.Robertson CAP is the enclosure of food in a gas impermeable package inside which the gaseous environment with respect to CO2, O2, N2, water vapor and trace gases has been changed and is selectively controlled to increase shelf life. O2 scavengers and ethylene absorbers with CO2 release agents could be classified as CAP during the early stages of the storage life of packaged product. MAP is the enclosure of food in a package in which the athmosphere inside the package is modified so that its composition is other than that of air. Modification can be achieved by removing air and replacing it with a controlled mixture of gases. Nitrogen is frequently used in MAP to reduce the concentration of other gases in the package.
Jupiter's white strips are formed by the tops of cloud formations in the planet's atmosphere which are formed by convection in the atmosphere modified by the coriolis force produced by the planet's rapid spin.
The Greeks added eight extra letters and modified the symbols for the letters.
