All quadrilaterals are alike because all of them have four sides, are coplanar, have two diagonals, and the sum of their four interior angles equals 360 degrees. Quadrilaterals can be different because they may or may not have parallel sides or equal sides, and there are many different types of quadrilaterals with special properties.
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.
B. the most dangerous job in the United States.
Mining is considered one of the most dangerous jobs in the World and 50-60 mining workers die in the United States every year. They are in danger from workplace accidents such as explosions, cave-ins and chemical leakages. Therefore it makes sense that this would be the answer.
Since they have been there for a long time, they have become coarsely!
Hope I helped! Just tell me if i'm wrong!
A convergent-plate boundary to the west of North America caused oceanic crust to be subducted, causing collisions with microcontinents and the partial melting of oceanic crust to create the Sierran volcanic arc.
<h3>Give an explanation of the plate tectonic conditions that led to the formation of the Sevier thrust belt and the Sierran arc. During the Laramide orogeny, what happened?</h3>
A convergent-plate boundary to the west of North America caused oceanic crust to be subducted, which led to collisions with microcontinents and the partial melting of oceanic crust that produced the Sierran volcanic arc. Compression was responsible for the arc's folds and thrust faults. As opposed to earlier orogenies that just established the more superficial faults of the fold-thrust belts behind the arc, faulting associated with the Laramide orogeny was responsible for the creation of the Rocky Mountains. The Sevier-style orogeny may have changed as a result of the subducting slab's shallowing dip.
