Simple industries: industries that do not change much from the original image, as they depend on local materials, and do not need large capital, for example: the preservation of fruits and vegetables, wood cutting, and trimming.
Modern industries: They are industries that rely on large capital, raw materials, manpower, and precise technical expertise.
Extractive industries: industries that depend on natural resources that are not compensated, such as cement industry, phosphate, and others.
Manufacturing industries: are industries that rely on converting semi-canned materials into fully manufactured goods, such as converting some vegetables into canned foods.
