EGD or Upper Endoscopy Procedure. The device used during an EGD procedure is called a flexible endoscope. It is tubular in shape and is very similar to the colonoscope that gastroenterologists use to examine a patientâs colon during a colonoscopy procedure, just thinner in diameter.
What causes ocean currents? Ocean currents result from two processes - the action of wind on the surface of the water, and from variation in water temperature that causes movement- a process known as convection. Convection occurs because the oceanic waters heat up becoming less dense.
yes surface currents are currently caused by wind!  because the global winds move the water, in the northern hemisphere, the winds moves clock wise, and in the southern hemis â¦ phere the winds move counter clock wise. and moves the water 400 meters under the water. 12 people found this useful.
