Ocean currents can be generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes. Currents are cohesive streams of seawater that circulate through the ocean. Some are short-lived and small, while others are vast flows that take centuries to complete a circuit of the globe.

The tough outer layer is used for leather shoes, garments, and upholstery, while the softer inner layer is cut and formed into different shapes for dog chews.ones are made from calcium. A typical bone has an outer layer of hard or compact bone, which is very strong, dense and tough. Inside this is a layer of spongy bone, which is â¦ like honeycomb, lighter and slightly flexible.
The rolled rawhide bones are more likely to cause fractures and break teeth. The rawhide bones may also be dangerous for the dog as chunks of bone may get stuck in the throat of the dog and cause choking. In addition, bone splinters can cause internal organ punctures. In some cases, the rawhide bones may be difficult to digest, especially if the dog has a diet that is poor in fibers. The rawhide bone residues may stay in the stomach and may even cause an intestinal obstruction. This condition may lead to surgery, if the condition is severe. Some dogs may be allergic to rawhide bones and these may cause vomiting and diarrhea.
