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.

If we have the intersection of the equator and the prime meridian as a starting point, and we move towards west, than the three oceans that we will encounter will be in the next order:
1. Atlantic Ocean; lies between Europe and Africa from one side (eastern borders), and North and South America on the other side (western borders). It is in fact our starting point.
2. Pacific Ocean; lies between Asia and Australia form one side (western borders), and North and South America from the other side (eastern borders).
3. Indian Ocean; lies between Southeast Asia and Australia (as its eastern borders) and Africa as its western border, and on the north it borders with South Asia.
The northernmost ocean on our planet is the Arctic Ocean, which is lying around the Arctic circle.
The southernmost ocean is the Southern Ocean which surrounds Antarctica with its waters.
