23) A detrital sedimentary rock composed of angular pebbles and rock fragments is called breccia. If those pebbles and rock fragments are rounded and smooth it is called: Conglomerate C. Cobblestone B. Pebblestone 24) Limestone is a biochemical sedimentary rock that is primarily composed of CaCO, in the form of which two polymorphs? D. Silica & Feldspar A. Silica & Basalt B. Tak & Beryl C. Calcite & Aragonite 25) Graded bedding is seen in turbidity current deposits. It means the sediments A. Get larger as you move vertically up the bed B. Are sporadically placed as seen in breccia Are fine grained, making a shale when lithified D. Get smaller (fine upward) as you move vertically up the bed. 26) When sedimentary rocks have a dark gray to black color it is most often due to the presence of organic material. What does the rock often contain if it has a reddish color? A. Cobalt B. Iron 28) Coal is formed from lithified A. Plankton C. Carbon 27) Varves are annual thin layers of clay and silt that are found in what depositional environment? A. Lakes B. Rivers C. Oceans material. C. Texture & viscosity 30) When transforming into a metamorphic rock, a protolith undergoes slow changes in B. Texture & mineralogy A. Shape & size 32) The direct protolith to gneiss can be either_ A Granite or schist D. Shale B) Plant C. Shale 29) When examining a sedimentary sequence that indicates past sea level fall, we call that period of retreat: B. Transgression A. Regression C. Flood Phase 31) Marble and quartzite are nonfoliated metamorphic rocks. The primary reason for this is: A. They are always foliated 8. The iron & magnesium content are too high. B. Limestone or marble C. Quartzite or shale D. Tin C.Micacious Blur D. Glaciers D. Dinosaur C. They are always contact metamorphic rocks. D. They are composed primarily of only one mineral 35) Why is marble more prone to dissolution by acidic precipitation than slate? A. It isn't. Slate dissolves readily in acidic precipitation D. Aggression D. Color & silica content D. Granite or marble 33) What is the name of the metamorphic rock that is formed through dynamic metamorphism, or shear forces, along fault zones? A. Gneiss B. Mylonite D. Slaty Cleavage 34) Slaty cleavage forms through metamorphic processes and has been incredibly useful when make slate roof tiles. What position are the cleavage planes relative to the metamorphic forces? A. Planes are at a 45° angle to metamorphic forces B. Planes are perpendicular to metamorphic forces C. Plane are parallel to metamorphic forces D. Planes are not a product of metamorphic forces B Marble is composed primarily of orthoclase making it vulnerable to weathering C. Marble is composed primarily of calcite & aragonite making it vulnerable to weathering D. Slate is composed of highly resistant onyx that makes it ideal for roofing tiles. 23) A detrital sedimentary rock composed of angular pebbles and rock fragments is called breccia.
