As a whole, all the above mentioned iron and steel centres lie close to the most densely peopled northemeastern part of the country, thus heving ho great difficulty in locating markets br export channels. Labour supply. and securing capital.
49. (a) Petroleum is derived from the remains of
marine life, both plant and animal, in the sedimentary strata of the earth's crust, which have been distilled under heat and pressure to produce drops of petroleum. Under favourable conditions in the rock strata these drops have accumulated to form large deposits.
011, together with salt water beneath it and gas sbove it, occurs in the gentle anticlinal fold of the porous rock. This porous rock layer must be sandwiched between two impervious rock strata so that oil is trapped therein. Moreover, the ares should not have been subjected to serious folding or faulting lest the oil might have escaped or evaporated.

In the United States and the Middle Kaat, this method is common. By sea, oil lo carried in specially built ships - tankers. As for local distribution of refined oil products, rail or road is used.

the location of the industry are (1) A supply of iron ore, which comes either from deposits in the focailty or is to be imorted. (2) source of sower: huge quantities of coal are required both for the heating purposes and a coke for use in the blast furnace. Since there is little difference between the weight of ore and the weight of fuel required to smelt it, so, all other factors being equal, the smelting of are may be carried out close to the quarries or at any convenient point, such as a meting place of comi and ore. (3) Easy communication means facilitate the assembly of raw materials and distribution of manufactured goods. Cheap water transport la con desired for. (4) Other enviromental factors include a reliable supply of water, flat land as factory sites, stimulating climates, and availability of labour as well as capital.

Though a great distance separates these two minerala, this is offset by the ease with which the iron ore sam be 'exosvated and the comparatively low gost of transport from Duluth by way of the Great Lakes va tarmy, But, to save both Lime and exPORES mình of the Son1:10 sent to set the ore at lakesias ports, ka a result, the most important iron and steel sanufacturing centres are situated at Chicago, Detroit, Cleveland, Buffalo and Pittsburgh. -Balngham to northern Alabam, shares part of this industrial growth because it has local supplies of good soling così and I imestone. In addition to risk deposite of beatite and limonite. However, as the Lake Superior tros ore deposits are within sight of axchaustion, the country has now to rely partly on high grade ore imported from Ventusla, Chile, Liberia and Knob Lake in Labrador. The recent years have vitaessed the rapid expension of the iron and steel industry: at Phaledelphia, bothlered and Sparrow's Paint
(a) The extraction of coal, or oil, is an exhaustiva industry. The opening up of a new field way bring a country quickly into prominenses, but the supplies may last only for a limited period. On the other hand, water power is inexhaustible and is derived indirectly from the sun, Water power 18
like coal when there is a day the seams may be worked out, or oil when the oil is gone and nothing is left but water.
Moreover, H.E.P. may be
carried cheaply by sable over large distances and therefore can be used in towns where industries have been established. Joal is bulky and coasts much to be delivered. Gases are not infrequent where towns dwindle in sise and importance as its coal seams become sxhausted. 011 transport is also a hazard problem io be faced, large tankere and long pipelines have co be specially constructed for the purpose.
"Which source of power shall be used in any situation is mainly a question of comparative cost. The initial capital expenditure in erecting a hydro- electric power station is usually very great, and laying down of the scheme requires great ingenuity and foresight. This may also necessitate the co- operation between countries through which the same river flow.
Coal and oil may be regarded as sources of raw materials as well as sources of power. The by- products furnish the necessary basis for chemical industries and many others. This is why H.E.P., aven where available, cannot be a good substitute for the other two at all lines.
