It depends on the species. There are some sharks, such as Nurse sharks, that lie on the bottom under a ledge or in a cavern for their naps during daylight. They aren't moving and they sure aren't dying. Their gills work just fine in a motionless state.
Then there are many other species, such as the Tiger that Do need to move in order to survive.

Not entirely true. Water must move over a shark's gills to pass oxygen to the shark's blood. Any fish can open its mouth wide and it will fill with water. When they close their mouth, it will force water over their gills like a pump. Sharks' lips don't seal well because of the jagged teeth hanging out. Some water is lost back out the mouth. Sharks PREFER to swim with their mouth open and let water flow over their gills, but, with extra work they can hover and mouth breath like any other fish.

Yes. Without motion to push water through the shark's gills, the animal will not be able to get enough oxygen, and will die. A few smaller species can get enough ventilation while still, but most cannot.

Sharks do not have fins near their gills that help water, thus oxygen, flow through their gills. That's why sharks need to in in constant motion to facilitate the water (oxygen) over their gills

NO it is not true, it's a proven fact that they do not die if they stop swimming. Sharks do have gills you know.

Yes. Sharks breath by running water over their gills and when they stop swimming they can't breath.

true for most sharks... they don't have swim bladders like most fish and they move water through there gills by movement.

Yes if they stop swimming they will die. and like most fish, as soon as they die depending on their mass they will indeed sink to the bottom.

think about what your asking, u think if a shark stops swimming it will suddenly just die, u think it will come to a stop wait 10 seconds and then just die and sink, what ridiculousness, what is causing this death?
