Lava is molten rock expelled by a volcano during eruption. This molten rock is formed in the interior of some planets, including Earth, and some of their satellites. When first erupted from a volcani...

is the resistance to flow (opposite of fluidity). Viscosity depends on primarily on the composition of the magma, and temperature. ... Lower temperature magmas have higher viscosity than higher temperature magmas (viscosity decreases with increasing temperature of the magma).

Temperature of magma is 1000-1400°C. Rhyolitic = Low Temp, Basaltic = High Temp. ... 4. Temperature: High temp = low viscosity ; Basaltic lavas can flow as fast as 10-15 km/hr. Andesitic lavas are more viscous than thick concrete. Rhyolitic? Barely can move.

The liquidus temperature of magma that reaches shallow levels during its ascent may change abruptly as a result of the release of volatiles or through magma mixing or a combination of both.

Normal heat fluxes from the Earth are sufficient to cause magma convection in plutons greater than 15 m for magma viscosities to 10 (super -8) poise. Convection increases markedly with size ... Large solidifying intrusions have an approximately isothermal temperature distribution during part of the crystallization history.
