Types of volcanic eruptions eruptions are associated with volatile-rich dacitic to rhyolitic lavas, and occur most typically at stratovolcanoes. Eruptions can last anywhere from hours to days, with longer eruptions being associated with more felsic volcanoes. Although they are associated with felsic magma, Plinian eruptions can just as well occur at basaltic volcanoes, given that the magma chamber differentiates and has a structure rich in silicon dioxide. Plinian eruptions are similar to both Vulcanian and Strombolian eruptions, except that rather than creating discrete explosive events, Plinian eruptions form sustained eruptive columns. They are also similar to Hawaiian lava fountains in that both eruptive types
Bait (luring substance) Bait (luring substance) Bait is any substance used to attract prey, e.g. in a mousetrap. The term is especially used with regard to catching fish. Traditionally, nightcrawlers, insects, and smaller fish have been used for this purpose. Fishermen have also begun using plastic bait and, more recently, electronic lures, to attract fish. Because of the risk of transmitting Myxobolus cerebralis (whirling disease), trout and salmon should not be used as bait. There are various types of saltwater baits that are natural. Studies show that natural baits like croaker and shrimp are more recognized by the fish and are more readily
