GLY 2010C Lecture Notes - Lecture 17: Magma Chamber, Igneous Rock, Flux Melting
Document Summary
Rock that forms by the freezing of lava above ground, after it flows or explodes out (extrudes) onto the surface and comes into contact with the atmosphere or ocean. (page 154) Fragmented material that sprayed out of a volcano and landed on the ground or sea floor in solid form. (page 154) A space below ground filled with magma. (page 154) The change in temperature with depth in the earth. (page 156) Melting that results from the transfer of heat from a hotter magma to a cooler rock. (page 157) The kind of melting that occurs when hot mantle rock rises to shallower depths in the earth so that pressure decreases while the temperature remains unchanged. (page 157) The transformation of hot solid to liquid that occurs when a volatile material injects into the solid. (page. The melting in a rock of the minerals with the lowest melting temperatures, while other minerals remain solid. (page 158)
