A) Convective flow adds more material to the base of the lithosphere, making it downwarp. B) Rotation of convecting mantle material smoothes out wrinkles in the surface. C) Hot rising material upwarps the landscape whereas downward flow causes downwarping. D) Subduction of oceanic plates disrupting the convective flow on the mantle, resulting in hot spots burning through the crust. Q. 2 - Which of the following best describes the formation of the Ural Mountains of Russia? A) Marine sediments that had collected in a basin were compressed and uplifted as the former Asian and European plates merged B) Marine sediments were sheared along a transform boundary between the Eurasian and African plates C) A continental volcanic arc formed as two microcontinents collided and subducted D) The landscape was pulled apart by rifting and flood basalts piled up on the landscape Q. 3 - Which of the following statements best characterizes the geology of western North America, starting in California and extending through British Columbia and up into Alaska? A) Divergent rifting creating deep, wide valleys with grabens B) Collision of a massive subcontinent of old igneous and metamorphic rocks, resulting in fold-and-thrust mountains that are still growing C) Geologically distinct, microcontinent-sized fragments and terraces accreted to the continent D) Metamorphosed accretionary wedges Q. 4 - What are fault-block mountains? A) Mountains formed through folding and thrusting of the crust B) Mountains consisting of exposed batholiths C) Mountains that form by erosion of streams D) Mountains formed through crustal extension and normal faulting Title: Which of the following best describes the effect of convective flow on the elevation of Earth's ...
