Answer: B. Metamorphic rocks
Explanation: Metamorphic rocks are those that have undergone changes due to extreme heat and pressure. Thus, the rock, from which it becomes a metamorphic rock, is heated at temperatures above 150-200 ° and exposed to a pressure of 1500 bar. In this way, the structure of the rock is changed, in terms of the arrangement of the atoms, and the result is a change of physical and chemical properties. There are two basic types of metamorphic rocks: foliated and slate. Generally, some of the metamorphic rocks are anthracite, schist, quartzite, marble, etc.

Answer:
The Niger River will be heavily exploited in the future so that it helps the economies in people in the region.
Explanation:
Most of the big rivers around the world are heavily exploited. They have huge dams built on them for multiple purposes, canals that connect places that don't come out on the rivers, transportation, and travel are well organized and on a high scale. The Niger River though is not that exploited despite having huge potential, but that will change in the near future for sure.
This river goes a long way in the interior of Western Africa and the outskirts of Central Africa. It can support boats, and it is the major factor that supports agriculture. Considering that this part of the world is in a dire situation but develops quickly, the Niger River will be used for sure. Huge dams will be made, and the water will be used for the production of electric power to feed the economies, but also for irrigation as the region is mostly semi-arid, for drinking, and for the industry. In order to boost the economy and help in the development of the large urban areas, canals will be made to the ones that are not located at the river's banks. Transportation through the river's waters will skyrocket as it will be fast, safe, and cheap.
That is incorrect. Subduction is when one plate moves under another.
