Action And Physical Properties Of Magma
[ send me this paper ]
An 8 page paper discussing the origin, movement and physical attributes of the substance that is known as lava once it exits its volcano. Formed under intense heat (up to 4300C) and pressure, magma has no choice but to rise. The absolute chemical composition varies according to location on the earth's surface, and chemical changes in the magma as it moves toward the surface opening it seeks can span a range of changes as minerals are precipitated out of the magma and sink downward through it again. Regrettably, old mudflows of prior eruptions appear to many to be good homesites as builders populate the paths of former mudflow channels with homes in the shadow of still-active volcanoes. Bibliography lists 9 sources.
