the shape of a volcano depends on the type of lava its made of the type of lava coming from a volcano depends on its mineral content some lava is so thick that it doesn't run but it does plug up the volcano! there is basalt lava lava comes out of volcanoes by tearing out chunks of the volcano and creating a bigger opening for it to escape a volcano erupts by hot rocks melting into magma and becoming less dense then the earth around it which makes it float to the surface of the earth. BY RACHEL AND MYCHAELA lava is just molten rock volcanoes the volcano in iceland has erupted and is erupting so much ash, it has made travel unsafe. volcanoes can be dangerous!!! hoped you liked our prezi!
