<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>
Answer:
About eight million people are reported to have died in the Cerro Rico since the year 1545. Reason being why the mountain has it second name to be popularly known as "the mountain that eats men".
It was also reported that four to five workers are being killed every month from mining accidents and mining related illness. Also, as miner numbers are increasing so the number of deaths.
Moreover, as more men are dying from mining accidents, another major causes of death in the Cerro Rico is silicosis. Silicosis is an incurable lung disease caused by inhaling large amounts of silica dust. It is was unfortunate that this is the biggest occupational hazard ever throughout the entire world.
The correct answer is: Alfred Wegener. Alfred Wegener (1880-1930) was a German polar researcher, meteorologist and geophysicist, and a first person who suggested that the continents were once a supercontinent called Pangaea, but slowly drifted apart. While he was still alive, Wegener was best-known for his achievements in <span>meteorology and as a pioneer of polar research, but today he is most remembered as the creator of the theory of the continental drift. This idea was controversial in the beginning, but today, scientist believe that Pangaea really existed during the late Paleozoic and early Mesozoic eras.</span>
