ASBOG Questions With Correct Review Solution Calculate the depth to a sandstone aquifer if a well is drilled at point X located 650 feet from the nearest sandstone outcrop in the N28°E direction. The sandstone strikes N62°W and dips 30°NE and outcrops in relatively flat terrain. - ANS-650(tan)30 A borehole was drilled to bedrock from the top of a west-facing ridge at an elevation of 360 feet. The bedrock is dipping east 35° under the ridge. The distance from the borehole to the bedr...

"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...

Sedimentary rocks (e.g. sandstone) b. Igneous rocks (e.g. basalt) c. Metamorphic rocks (e.g. marble) Sedimentary rocks (e.g. sandstone)

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...
