Ch. 7 Volcanoes

Ch. 7 Volcanoes . Ch. 7.1 Volcanoes and Plate Tectonics. Most rock in the very hot mantle / asthenosphere remains solid due to very high pressure. Sometimes conditions (lower pressure or added water) allow part of the solid mantle to melt and become flowing liquid magma. Volcanism.
