Drilling revealed about 1,400 metres (4,600 feet) of reef material. At least two writers have attacked the young age position using the argument that this coral atoll must have taken a very long time to form 1,2 âthey estimate 138,000 and 176,000 years respectively as the minimum age for Eniwetok.ack of light will of course kill a reefâno live coral growth takes place below about 50 metres under the surface. Hence thick atolls such as Eniwetok require the ocean floor to sink as the coral builds. As the coral is lowered, faster growth is possible than that which we measure at the surface.
Swallowing certain types of poisons may cause excessive salivation. According to the National Library of Medicine, pesticides can cause excessive saliva when they are swallowed. Venom from snake bites or insect stings is another type of poisoning that can cause the malady.
Causes of Salivary Gland Problems. Many different problems can interfere with the function of the salivary glands or block the ducts so they can't drain saliva. The following are some of the more common salivary gland problems: Salivary stones, or sialoliths. The most common cause of swollen salivary glands, salivary stones are buildups of crystallized saliva deposits. Sometimes salivary stones can block the flow of saliva. When saliva can't exit through the ducts, it backs up into the gland, causing pain and swelling.
