chapter 6 test Essay Example chapter 6 test Paper chapter 6 test Paper the water cycle is the unending circulation of earths water supply plants release water into the atmosphere through a process called transpiration balance in the water cycle means that the average annual precipitation over earth equals the amount of water that evaporates the ability of a stream to erode and transport material depends largely on its velocity the single most important erosional agent on earth is running water if you were to examine the profile of a typical stream, you would probably find that the gradient is steepest near the head a streams discharge increases between its source and mouth base level is the lowest point to which a stream can erode its channel what is the ultimate base level of a stream the ocean most streams carry the largest part of their load in suspension the suspended load of a stream usually consist of fine sand, silt, and clay sized particles a depositional feature that forms where a stream enters an ocean is a(n) delta in a stream channel, which of the following will be deposited first gravel sized particles the flat portion of a valley floor adjacent to a stream channel is called a floodplain the most prominent features of a narrow, v shaped valley, where the stream profile drops rapidly are rapids and waterfalls one traditional flood control method has been to attempt to keep the streams flow within its channel by creating artificial levees a drainage basin is the land area that contributes water to a stream groundwater is found underground in the zone of saturation permeable rock layers or sediments that transmit groundwater freely are called aquifers the percentage of the total volume of rock or sediment that consist of pore spaces is called porosity springs form where the water table intersects the ground surface which of the following is a measure of a materials ability to transmit fluids through interconnected pore spaces permeability when groundwater enters underground fractures or caverns in hot igneous rocks, where it is heated to boiling temperatures, what feature can form geyser which of the following statements is true about stalactites they hang from the ceiling of a cavern which of the following is associated with areas of karst topography sinkholes/ sinking streams/ caverns the release of water vapor into the atmosphere by plants is referred to as transpiration the _____ of a stream is the amount of water flowing past a certain point in a given unit of time discharge the maximum depth to which a stream can erode is called base level an accumulation of sediment formed where a stream enters a lake or the ocean is called a(n) delta a(n) _____ is the flat, low-lying portion of a stream valley that is covered with water during floods flood plain artificial levees and dams are structures used to control flooding the land area that contributes water to a stream is referred to as the streams drainage basin the upper limit of the zone of saturation is called the water table an intermittent hot spring in which a column of water shoots up with great force at various intervals is a(n) geyser groundwater _____ can be caused by leaking septic systems, leaking landfills, and agricultural chemicals contamination what are the 5 major processes that are involved in the water cycle evaporation/ precipitation/ infiltration/ transpiration/ runoff the 3 ways streams transport sediments are dissolved load/ suspended load/ bed load in a stream that carries gravel, sand, silt, and clay sized sediment, explain how these sediments would be deposited the biggest thing drops firstgravel, sand, silt, clay what river has the largest drainage basin in north America Mississippi briefly describe the 2 ways that sinkholes can form slowly over a number of years as groundwater dissolves limestone, bed rock, below the soila cavern caves in
