Lighting
Information on the globe lighting zones Lighting zones are defined by the Tropic and the Arctic circle. Characterized by changes in lighting conditions during the year. There are five lighting zones, the Earth: mi(tm)discreetness's..., two zones of moderate width, and the two Arctic zone. Differentiation lighting affects many of interrelated phenomena, such as air temperature, ground temperature, atmospheric pressure, climate and so on. Along with changes to the lighting changes the Earths vegetation period, IE, the period during which they can grow plants. In the area mi(tm)discreetness's last for the entire year, but in temperate zone, it no longer reduces with increasing latitude. In the area okraaubergine growing period is limited to almost zero, hence the inability to plant any crops there. The length of the period of vegetation is one of the factors of development, or the fall of many civilizations. This is an extremely important factor which is taken as one of the most important in the analysis of human civilization. Lighting of the Earth causes the diversity of natural conditions and contribute to economic diversity on our planet. The rhythm changes of lighting has become the basis for Rachael time.
