The Congo and Niger rivers have interesting irregular courses, and instead of going just in a certain direction, they circle around big areas. This is due to the shape of the landscape, and also because of the types of rocks in the surrounding areas where these two rivers flow.
The shape of the landscape is crucial in the course of a river, since every river is moving through the lowest parts where there isn't obstacles, so these rivers have followed that pattern and it turned out to give them irregular course. Also, the types of rocks on their way are very important, so these rivers managed to get through the sediment rocks as they are easy to erode, but haven't been able to break through the igneous rocks that are much harder.

Answer: The potential energy in the system is greatest at X
Explanation: Potential energy is how much energy an object can have. Gravity has an effect on potential energy, the higher something is, the more potential energy it has. For example, if you hold a book above your head, that book has potential energy. When you drop the book, it has kinetic energy. Therefore, since point X is the highest point, the ball has the greatest potential energy there.
