Moving from the earth's crust towards the earth's core, temperature _____________ and pressure _______________. - increases; increases Large crystal size is associated with what type of rock? - Intrusive igneous Rocks found within the core of a mountain range formed along a continental-continental convergent plate boundary are likely to be: - Metamorphic processes associated with a mid-ocean ridge - Mantle convection Plate divergence Crustal formation When oceanic crust collides with continental crust: - the oceanic crust is subducted under the continental crust. Explosive volcanic eruptions that eject large quantities of pyroclastic materials are associated with what type of high silica content, highly viscous magma? - Felsic Anticlines and Synclines are the product of what type of tectonic force? - Compressional force forms of physical weathering - Frost wedging Pressure release jointing Salt wedging forms of chemical weathering - oxidation, hydrolysis, and acid rain Chemical weathering occurs most rapidly under what climatic conditions? - Wet and warm The deep red color of soils in the southeast coastal plain of the US and humid tropical climates is the result of what process? - Oxidation important factors contributing to the destruction of the recent California wildfires: - -housing development in LA hills -high temperatures and a lack of rain -government policy of putting out all fires during the last 100 years -strong, off shore winds coming from high pressure points in the interior of the continent Why don't desert biomes experience wildfires? - they lack the appropriate amount of fuel needed to maintain a fire (plants) What type of rock would you expect to find at a location that was a river delta many millions of years ago? - sedimentary Abraision - stream erosional process leading to the rounding of stones transported in stream channels The portion of the Amazon River that flows across a broad floodplain of easily eroded fine sediment likely exhibits what channel morphology? - meandering The Hawaiin island chain is an example of what process? - hot spot fluvial landforms is associated with lower stream velocity and deposition of sediment - point bar Sedimentary rocks are formed when _______________ rock is weathered, eroded, transported, deposited, and then lithified (compacted and hardened) to form sedimentary rock. - any rock, whether it's sedimentary, metamorphic, or igneous
