A large volume of air that has nearly the same temperature and humidity at different locations at the same altitude is called the Air Mass. Air mass covers hundreds or thousands of square miles and adapt to the characteristics of the surface below them at the same time they are also classified according to latitude and their continental or maritime source regions.
Answer:
Lack of technocrats.
Explanation:
There is a widely known phrase in mining industry in Africa, its called the "resource curse". In countries like Nigeria, which produces mammoth amount of Oil all year round, the proceeds from oil is not evenly distributed to better the lives of the masses. Profits derieved from oil is expected to help fund education and training of expats. It is not the case. Thereby, we hear of the oil curse.
It is widely believed and statististically proven that Africa lacks adequate and capable technocrats to harness its vast resources.
Africa owns the resources and the West have the brains to harness them. The Western countries have the right technologies and financial capabilities to explore and produce oil in Africa.
Africa is not as technologically bouyant as the West and does not have the right structure to tap its vast oil reserves. Technologies have to constantly be imported from foreign countries. Most companies believes that it is cheaper to import foreign technocrats with an excellent track record than to start training new ones and deploy them to work in their various climes.
Although, there has been a rigorous drive through indigenous policies to bring up more Africans into the oil industry.
Answer:
Explanation:
The refractive index of the suspected glass can be known by using the backe- line method. This process takes place in a petrographic microscope. In this method an oil comparable to the refractive index of the glass is used. At a point when the refractive index of the glass becomes equal to that of the oil in which it is immersed the yellow line under the observation of the plane polarized light gets disappeared. This method can be used to identify the refractive index of the suspect glass and comparing it with the source of origin or sample glass.
