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.
By definition, all igneous rock is formed from magma. Magma is a complex high-temperature fluid substance. Temperatures of most magmas are in the range 700Â°C to 1300Â°C, but very rare carbonate melts may be as cool as 600Â°C, and komatiite melts may have been as hot at 1600Â°C. Most are silicate solutions. It is capable of intrusion into adjacent rocks or of extrusion onto the surface as lava or ejected explosively as tephra to form pyroclasic rock. Environments of magma formation and compositions are commonly correlated.
