EOSC 210 EXAM QUESTIONS AND ANSWERS ALL CORRECT How do minerals form? - Answer- cooling and crystallization from magma; precipitation from fluid; chemical changes from heat and pressure; precipitation from biogenic activity (biomineralization) How do we identify minerals? - Answer- 1. Physical properties: colour; lustre; streak; hardness; cleavage; fracture 2. RXN to acid; magnetism; taste; radioactivity; specific gravity; habit Silicate Minerals classification - Answer- classified bas...

Metamorphic rock correct answers A type of rock that forms from an existing rock that is changed by heat, pressure, or chemical reactions. (Ex: Gneiss, Marble, Quartzite) Magma correct answers A molten mixture of rock-forming substances, gases, and water from the mantle Igneous rock correct answers a type of rock that forms from the cooling and hardening of molten rock at or below the surface (Ex: Basalt, Granite, Obsidian) Metamorphic and Igneous rock melts and turns into correct ans...

EOSC 118 FINAL EXAM QUESTIONS AND ANSWERS GUARANTEED PASS 2024 LATEST UPDATE What are common treatments for corundum? - Answer- Heating to improve clarity, diffusion treatment to add colour. Usually done before it's cut. Can corundum be produced synthetically? - Answer- Taking the necessary oxide components in powdered form, melting them together in a container and a seed crystal is lowered in and slowly removed causing it to be continually grown below it. How does corundum form in ...

2 types of Lustre ~ 1. metallic 2. non-metallic Basic 3D mineral form ~ tetrahedron Softest, hardest mineral according to mohs scale of relative hardness ~ talc, diamond Conchoidal fracture ~ smooth curved surface 3 components of magma: ~ 1. melt 2. solids 3. volatiles Geothermal gradient ~ heat increases with depth in crust Igneous rock ~ cooled magma Extrusive igneous rock ~ magma solidified at surface Intrusive igneous rock ~ magma solidified at depth Plutonic rocks ~ i...

Which of the following sedimentary rocks is usually biochemical in origin? a) bedded salt b) conglomerate c)sandstone d) wacke e) limestone ~ e What platy, parallel, mineral grains are the most visual aspect of foliated metamorphic rocks? a) carbonates b) quartz c) cocoliths d) micas e) feldspars ~ Lava flows are typically finer grained than intrusive igneous rocks. Why? a) The extrusive magma, because it is deep below the surface, cools very slowly producing very ...

GACE Middle Grades Science Exam Questions With 100% Correct Answers Tidal hypothesis - answerTheory that the solar system started with a near collision of sun and large star. Few astronomers believe this theory. condensation hypothesis - answersolar system began with rotating clouds of dust and gas. Condensation happened in center to form sun, and smaller parts of clouds formed. More astronomers believe in this idea. Core - answerOuter core- liquid; inner core- solid. Very dense in center...
