Chapter 3: Rock, Materials of Earth Science The Rock Cycle * Earth consists of many parts form a complex whole * Rock cycle: interrelationships among different parts of Earth System - Origin of igneous, sedimentary, and metamorphic rocks (each type linked to others by processes) * The Basic Cycle - Magma is molten material forms inside Earth -> cools and solidifies (crystallization) beneath the surface or at the surface (following a volcanic eruption) -> Results in Igneous Rocks - Igneous Rocks exposed at surface, undergo weathering -> materials moved downslope by gravity -> transported via agents (running water, glaciers, wind, waves) -> particles and dissolved substances (sediment) deposited - Sediments undergo lithification (conversion into rock) -> Sedimentary Rock when compacted by weight of layers or cemented as groundwater fills pores with mineral matter - Sedimentary Rock buried deep and subjected to great heat/pressure -> turn into metamorphic rock - Metamorphic Rock subjected to higher temperatures -> melt -> create magma -> crystallize into Igneous Rock -> start cycle again
