Oct 31, 2014 ... This huge increase in temperature allowed just one magma well to generate
roughly 36 megawatts of electricity, powering 36,000 homes.
Magmas form in the crust and upper mantle, within 200 km (most much ... depths

When the mantle partially melts to form basaltic magma, we are primarily
concerned with the mantle solidus temperature, in part because the mantle rarely
Why do granitic (felsic) magmas usually crystallize before reaching Earth's
surface. Why are ... Magma Temperature - higher temperature = lower viscosity (
Magma is molten rock found below the earth's surface. The temperature at which
a rock melts is affected by its composition, pressure and water....
Magma composition is discussed below, followed by a description of the
controlling factors on explosivity -- viscosity, temperature, and the amount of
<sup>3</sup> Magma forms when rocks reach temperatures high enough to melt them. Most
rocks begin to melt at a temperature between 800 and 1200 degrees Celsius.
