By Friday, THE FIRST DAY OF THE ACTUAL FESTIVAL, Woodstock Ventures was out of food. Then they had the gall to ask their confined neighbors for sandwich donations. About 750,000, if they didn't mind. Some locals felt so sorry for the hungry kids that they did what they could to help.
Basaltic magma is hotter, denser, and less viscous than most other  types of lava. It is poor in silica and rich in iron and magnesium.  Eruptions involving it are typically â¦ non explosive or only mildly  explosive.It is less dense, more viscous, and cooler than most other types of  magma. It usually has a very high gas content, meaning that most  eruptions involving it will be highly explosive. Most  supervolcanoes are fed by rhyolitic magma.
Non explosive eruptions are favored by low gas content and low viscosity magmas (basaltic to andesitic magmas). If the viscosity is low, non-explosive eruptions usually begin with fire fountains due to release of dissolved gases. When magma reaches the surface of the earth, it is called lava.Since it its a liquid, it flows downhill in response to gravity as a lava flows. Different magma types behave differently as lava flows, depending on their temperature, viscosity, and gas content.he initial composition of the magma is dictated by the composition of the source rock and the degree of partial melting. In general, melting of a mantle source (garnet peridotite) results in mafic/basaltic magmas. Melting of crustal sources yields more siliceous magmas.
