Sedimentary rock - Study guides, Class notes & Summaries

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...

"Bauxite" Al(OH) 3 (the ore for Aluminum) - Under extreme chemical weathering conditions (e.g. the tropics), hydrolysis can remove nearly all of the available cations, leaving behind only 1st Step of Forming Sedimentary Rocks - Chemical and mechanical weathering break down rock 2nd Step of Forming Sedimentary Rocks - Erosional Agents transport sediment 3rd Step of Forming Sedimentary Rocks - Deposition occurs when solid particles settle out or when ions in solution are precipitated by ino...

core : Center of the earth; composed of iron and some nickel; solid inner core & liquid outer core mantle : the layer of of earth outside the core; mostly solid and makes up about 70% of Earth's volume crust : the rocky outer shell of the planet lithosphere : thin, upper part of the mantle and the outermost crust; the rock consists of cooler, brittle rock asthenosphere : below the lithosphere; contains malleable rock that can move over time igneous rock : molten magma that has ...

silicates - minerals that contain silicon and oxygen and usually one or more other elements, are one of the largest groups of minerals oxides - compounds that have oxygen as their anion, t ut they exclude those with oxygen complexes such as carbonate, suphate, and silicate. have O2 as their anion, Ways rocks may form - Igneous: forms from magma that has either cooled slowly under ground or cooled quickly at the surface after a volcanic eruption Sedimentary rocks: formed when weathered frag...

Fossils Science Olympiad Latest Update Graded A+ Conditions required for a plant or an animal to become fossilized Hard body parts (bones, teeth, shells) - soft body parts will not fossilise, but may leave behind trace evidence (e.g. imprints) -Preservation of remains (protection against scavenging, erosion and environmental damage) -High pressure to promote mineralisation of remains (i.e. turn hard body parts into fossilised rocks) -Anoxic (low oxygen) conditions to protect against ...

Geology Exam Questions With Answers Diagenesis refers to ________. physical and chemical alterations, including compaction and cementation, that occur as sediment is transformed into rock Pulling a block of clay apart, resulting in the middle portion thinning and sinking, is an adequate analogy for ________. rift basins and subsidence Lithified detritus (breakdown products of preexisting rocks) forms which kind of sedimentary rock? clastic Cemented shells of marine organisms f...

GACE Middle Grades Science Latest Update with Verified Answers tidal hypothesis Theory that the solar system started with a near collision of sun and large star. Few astronomers believe this theory. condensation hypothesis solar 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 Outer core- liquid; inner core- solid. Very dense in center. Believed that core is...

Description 2 More sediment covers and squeezes the shell. It may undergo mineralization or other processes that make it more stone like. Des...
