| Oceanography | the branch of science dealing with physical and biological aspects of the oceans |
| Geomorphology | the branch of geology that studies the characteristics and configuration and evolution of rocks and land forms |
| Downcutting | downward erosion or vertical erosion is a geological process that deepens the channel of a stream or valley by removing material from the stream's bed or the valley's floor. |
