<span>Erosion is the displacement of solids (soil, mud, rock and other particles) by the agents of wind, water or ice, by downward or down-slope movement in response to gravity or by living organisms (in the case of bioerosion).
Deposition, also known as sedimentation, is the geological process whereby material is added to a landform. This is the process by which wind, water or ice create a sediment deposit, through the laying down of granular material that has been eroded and transported from another geographical location.
Deposition occurs when the forces responsible for sediment transportation are no longer sufficient to overcome the forces of particle weight and friction, which resist motion. Deposition can also refer to the build up of a sediment from organically derived matter or chemical processes. For example, chalk is made up partly of the microscopic calcium carbonate skeletons of marine plankton, the deposition of which has induced chemical processes (diagenesis) to deposit further calcium carbonate.</span>
Infrastructures affected include those who are most vulnerable to the weather conditions such as Power lines and road and bridge. The harsh conditions damages these infrastructures. A damage in any of them usually cause a ripple effect and also affects others indirectly too.
This affects the economy by a steady decline being noticed because the economy is usually run on these infrastructures.
Gorges are narrow/skinny valleys between hills or mountains that often have a stream or river running through it. Waterfalls are rivers that stop and drop vertically into another body of water.
Over 96% of Earth's water is saline (salty) and found in the ocean. Only a little over 3% of Earth's water is fresh. Most of that freshwater (68.7%) is frozen in glaciers and ice caps.
