"Dredge" is the general usage in America and ,,dredger" is used in most parts of the world.
Dredger is defined as a vessel that is used to excavate the sediments from the seabed with the purpose of:
- Creating new harbors, waterways, bridges, docks
- Maintaining the channels or waterways clean
- Land reclamation
- Mining on the seabed
- Beach nourishment
- Deepening the waterways
- Extracting minerals from underwater deposits
- Removing polluted sediments from rivers, harbors basins
The dredgers can be classified in 2 categories:
- Mechanical Dredgers: involves the use of grab or bucket to loosen the material taken from the seabed
- Hydraulic Dredgers: they are loosening the material through a pipe system connected to a centrifugal pump
- Amphibian Dredgers

What is the different between placer mining and quartz mining?

How old is the oldest animal?
The Giant Tortoise seems to be the animal with the longest life span. For years, the oldest known living animal was a Giant Galapagos Tortoise named Harriet. The giant tortoise was taken from the Galapagos Islands by naturalist Charles Darwin in 1835 as a personal pet during his five-year voyage on the HMS Beagle. On that voyage was a young naval officer, John Clements Wickham. After studying Harriet whilst formulating his theory of evolution, Darwin handed the tortoise on to Wickham when the latter sailed for Brisbane to take up a post as police magistrate. Over the years, the tortoise was carefully tended, and in 1958, was moved to naturalist David Fleay's wildlife park on the Gold Coast. She was moved to Australia Zoo on the Sunshine Coast in 1987 where she enjoyed celebrity status until her death on 23 June 2006.

How do you solve a rubik's cube revenge?
First you solve one center (normally black or white). Then you solve the opposite center (often yellow), usually utilizing a single algorithm to individually place center-corners into their slots. Then, solve the rest of the centers. After that, you pair up the identical "dredges", which are essentially the edge pieces. You'll notice that on a solved Revenge, there will be two of the same edge. These are the pairs I'm referring to. Once that's done, you solve it like a normal 3 x 3, treating the dredges like single edges, moving only outer layers so as to not disturb them. Parity sometimes occurs in two forms: permutation and parity. There are specialized algorithms for these cases.
