The drawing of the boundaries in the manner of the interest of the European colonial powers resulted in very big problems once the African countries were granted independence.
The problems were mostly because people from the same ethnic groups were separated by borders, but were in the same ones with people from other ethnic groups, usually historical rivals with whom they had bad relations. Also, the religious factor had a big influence, as there were multiple countries were some parts were predominantly of one religion, and other parts of other religion, and that brought in even more tensions.
That has resulted in instability, constant tensions, civil wars, terrorist organizations, separatist movements, genocides, pretty much everything that is not supposed to happen for a country to prosper.
At low latitudes, the thermocline is a zone of rapid temperature
over a relatively short depth. it is associated with a similar depth zone marked by a change in density called the pycnocline.
Answer: Gneiss
Explanation: Gneiss is a metamorphic rock formed from shale at very high temperature and pressure condition. They exhibit a preferred alignment or orientation of platy minerals called foliation. They are coarse grained and exhibit gneissose banding. They are formed from highest grade regional metamorphism with temperature between 450 - 600 degree celcius and pressure between 800 - 1000 mega pascal. They generally occur in cores of fold mountain belts where mountain ranges have been eroded.
