2022 ASVAB General Science Solution guide. Geology - The study of the planet Earth as it pertains to the composition, structure, and origin of its rocks. What's a Mineral? - Naturally occurring, inorganic solids with a definite chemical composition and orderly internal crystal structure. Polymorph - two minerals that have the same chemical composition but a different crystal structure What's a Rock? - Aggregates of one or more minerals, and may also contain mineraloids, and organic remains. An Aggregate is? - A material or structure formed from a loosely compacted mass of fragments or particles. What's a Mineraloid? - Materials lacking in crystalline structure. What are the three types of Rocks? - Sedimentary, igneous, metamorphic How is a rock classified? - Based on both their formation and material content. How is a Mineral classified? - By their chemical composition. Petrology - scientific study of rocks (Composition, structure, texture, occurrence, mode of formation, and history.) Mineralogy - the study of minerals How are sedimentary rocks formed? - By the process of lithification, involving compaction, the expulsion of liquids from pores, and the cement action of pre-existing rock. Which is a part of the process of forming at Sedimentary rock? - Pressure and temperature Where are sedimentary rocks formed? - In layers in the presence of water, it also may contain organic remains such as fossils What are the three groups of Sedimentary rocks? - Detrital, Biogenic, Chemical How is igneous rock formed? - From magma cooling. Where is Magma located? - beneath the earth's surface TBC...
