Question

I. Why are petroleum refineries called “nodal industries”?

II. The mining industry is called a “killer industry”. Discuss.

Answer 1

Hint: I. Nodal industries are those businesses around which other fringes or supporting enterprises create. These periphery adventures manufacture the product required by the nodal ventures. Iron and steel and oil enterprises are nodal ventures.
II. It is risky for the soundness of excavators who frequently need to work in dangerous conditions in underground mines. Successive mishaps happen in mines because of the breakdown of rooftops and water flooding.

Complete step-by-step solution:
Petroleum refineries go about as a 'nodal industry' for engineered material, compost, and various compound ventures. During fragmentary refining of mineral oil, aside from petroleum, diesel, and lamp oil which go about as fuel, various side-effects like Naptha, phenyl, paraffin wax, black-top, or tar and various petrochemicals are obtained. Substance manures, bug sprays and synthetics, fake filaments, and counterfeit elastic are results of petrochemicals. Subsequently, petrochemicals, give crude materials to composts, various synthetic compounds, manufactured materials,
Example: engineered elastic and plastic enterprises.
Mining is known as the executioner business because of the accompanying reasons: It is hazardous for the strength of diggers who frequently need to work in dangerous conditions in underground mines. Incessant mishaps happen in mines because of the breakdown of rooftops and water flooding. These winds up causing numerous losses. Diggers are presented to harmful materials causing illnesses of the lungs and decreasing the future. Model: Black Lungs brought about by breathing in coal dust. It negatively affected our current circumstance as volumes of dangerous trash are delivered during the extraction of minerals from the mines causing natural corruption and contamination.

Note: I. Since it gives fuel to warmth and lighting, oils for hardware, and crude materials for various assembling businesses like manufactured material manure and various synthetic enterprises. That is the reason oil is called a nodal industry.
II. In mining, there is a high danger required. Due to harmful exhaust the laborers are in high peril, the danger of falling mines rooftop and flames in coal mine shafts and the water sources sullied.
