<em>Johann Heinrich von Thunen</em> was an economist who developed a model of land use in early nineteenth century. The model showed that how various market process can determine the land use pattern in different location. He was a skilled farmer who had knowledge in economics. According to the four rings for land use, dairying and intensive farming must be done in the ring central to the city so that the products can reach the city easily. <em>Timber and firewood</em> should be produced in the second ring because wood is heavy and difficult to transport. The <em>field crops</em> must be located in the third ring and <em>ranching</em> should be done in the outer ring.
According to von thunen's model, the one that would be produced most profitably on the ring farthest from the epicenter would be : B. Sheep
Von Thunen's model divided earth's region into 4 parts depending on what product that would be most profitable. according to this model , the farthest from epicenter is most suitable for Ranching/Animal Products
The EMS that is radiated from the sun in the form of solar rays reaches the earth and is absorbed in various places on the earth thus creating an energy balance with the incoming and the outgoing energy that is again reflected space in the form of long-wave terrestrial radiation.
The sun's energy is not distributed equally as the tilt of the earth and at the onset of the sunlight that falls directly on earth which is equivalent to one billionth of a fraction of energy that the sun radiates in the form of corpuscular energy.
Energy fall of the earth is 100% in which the outer surface reflects 35 units to space, 27 forms the cloud top, 2% form the snow and ice. 6% of the units by the inner atmosphere and the 65 % units get absorbed.14% in air and 50% in the ground, thus the atmosphere absorbs about 48% of the units.
History was a driving force behind such migration, since humans tended to move to new territory when they lacked food, shelter, or other resources--meaning that most of the conflicts throughout history have been driven by the same forces that drove migration out of Africa.
