GEOG 2051 - Namikas FINAL EXAMS QUESTIONS AND ANSWERS VERIFIED 100% CORRECT glacial-interglacial cycles during the Pleistocene are thought to be related to temperature fluctuations associated with - ANSWER -alpine glaciers which of the following would not be considered part of the cyrosphere? - ANSWER -none of the above 90% of the Earth's glaciers are found where? - ANSWER -antarctica new global ice forms mainly in the ablation zone of the glacier. T/F - ANSWER false the icy pellets orgranules that form as an intermediate stage between snow and glacial ice are known as - ANSWER -firn glacial ice forms - ANSWER -stagnant a glacier in which mass losses due to melting, are just balanced by the formation of new ice is said to be - ANSWER -above the snow line global erosion is similar to that caused by the wind in that abrasion and deflation are the major processes involved. T/F - ANSWER -false bowl shaped depressions created near the peaks of mountains by the formation of alpine glaciers are called - ANSWER -cirques the flow of glacial ice results from - ANSWER -basal slip and internal deformation river valleys that have been glaciated can be recognized by their characteristics - ANSWER -U-shaped cross-section the sharp, jagged mountain peaks formed by glacial erosion are called - ANSWER -horns sediment that has been laid down directly by glacial ice tends to be sorted into layers of different sizes. T/F - ANSWER -false terminal moraines are composed of - ANSWER -till the layer of soil that thaws out annually in an area underlain by permafrost is known as the _____ layer - ANSWER -active are areas of unfrozen ground (often beneath water bodies) within the continuous permafrost zone - ANSWER -taliks what does longitude mean when on the prime meridian? - ANSWER -east to west what affects a wave? - ANSWER -all of the above longshore currents occur in the swash zone. T/F - ANSWER -false this kind of eruption has low viscosity, has a soft and non-violent eruption, mafic magma, and is usually shield volcanos - ANSWER -effusive eruption this kind or eruption has high viscosity, has a violent eruption, felsic magma, and is usually composite volcanos - ANSWER -explosive eruption point on earth's surface that is right directly above the facial point; where the most energy is being released? - ANSWER -epicenter what form of weathering is oxidation? - ANSWER -chemical weathering what form of weathering is exfoliation? - ANSWER -physical weathering what are the climates for physical and chemical weathering? - ANSWER -physical weathering is in drier, cooler temperatures chemical weathering is in warmer areas with more rainfall mutual force exerted by masses of an object's attraction to another - ANSWER gravity rocks that are formed through melted lava - ANSWER -igneous rocks what requires testing? - ANSWER -theory reduce levels of wave energy acting on the coastline so it will reduce of erosion or redirects the path of the sediment is moved along; it reduces or eliminates the loss of sediment - ANSWER -hard shoreline protection tries to work with the natural systems to mimic the systems already there like adding sand and replace materials that were lost to erosion - ANSWER -soft shoreline protection series of changes in the wave as the sediment begins to move - ANSWER -wave shoaling wind blows along the water and as the wind moves along the surface, it picks up small water molecules that continuously build up into waves - ANSWER -wave generation waves move at different speeds as they enter different water depths; bending process that concentrates wave energy on headlands and disperse it in coves and bays - ANSWER -wave refraction high part of wave - ANSWER -wave crest low part of wave - ANSWER -wave trough difference between 2 successive wave crests and troughs - ANSWER -wavelength spring tide occurs every - ANSWER -2 weeks
