Volcanoes can form underwater thats how Hawaii was made
Remember the saying,
<em>"Give a man a fish and he will eat for a day, teach a man how to fish and he will eat forever"</em>
Well the Gopniks in Russia wrongly translated with saying to: teach a man how to become a fish and he will eat forever. So during the 1970-90s the gopniks all gathered near the lakes in order to satisfy their famine from communist regime. Unfortunately humans can not breathe under water so, fisherman in present day are still recovering bodies from the bottom of these lakes of these gopniks. Thousands still remain in lakes across this nation.
Into tropical savannas or steppes, in Africa, tropical wet climates transition into seasonally wet or dry tropical woodlands, followed by another transition.
The tropical savannas are identified by tall grasses and occasional trees. It can result from either climate, soil conditions, animal behavior, or agricultural practices, which limit the occurence of trees.
