Bimodal volcanism of back-arc basin formation and in the products of both continental and oceanic hotspots (e.g. Yellowstone and the Canary Islands). Bimodal volcanism is normally explained as a result of partial melting of the crust, creating granitic magmas, during the emplacement of large volumes of relatively hot basaltic magma from a mantle source. The two magma types then form separate magma chambers giving rise to periodic eruption of both types of lava. Bimodal volcanism Bimodal volcanism is the eruption of both mafic and felsic lavas from a single volcanic centre with little or no lavas of intermediate composition. This type of
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
