  1. The river system is divided into three different zones; they are named as sediment production, sediment deposition, and sediment transportation.  The zone of sediment production is in the headwaters region of the river system.  Hence, the sediment production is located at Zone 1 in the diagram.  The water in a river slows when it reaches the ocean and the energy to transport sediment is greatly reduced.  Most of the sediment (either accumulate at the mouth of the river to form a delta) is moved far offshore by ocean currents.  Hence, the sediment deposition is located at Zone 3 in the diagram.  Sediment acquired by a river transports through the trunk stream. Hence, the sediment transportation is located at Zone 2 in the given diagram.
  2. In a jar containing water collected from a stream, only suspended particles like slit, clay, fine sand will be settled at the bottom of the jar after a certain time.  Dissolved minerals will remain in the water.  Bottom weight of the river will never be present in the sample of the world.
  1. The ice sheets have fresh water trapped in the and the level of sea does not rise with their formation, but the level of sea rises when the ice sheets start melting.  The ice sheets are responsible for changes in the surface albedo and the change in the shape of geometry of ice sheets leads to affecting the climates of globes.  The rivers flowing into the oceans also freeze due to the expansion of ice sheets.  The ice sheets are formed at temperatures less than melting points and when rivers enter the oceans at these temperatures the rivers also gradually freeze.  With the melting of glacial ice, the rivers which flow into the ocean will increase the level of sea and the river take diversions into channels, tributaries, and details.
  2. The behavior of the stream likely changes upstream from the Lake Powell creating backwaters and the water of the stream are stored to the fullest at the reservoir making it second largest reservoir of the United States.  The Colorado River which feed on the tributaries of the reservoir of Lake Powell will dump more amount of water into the reservoir during runoff of the spring which will help in generating the power and the volume of the reservoir increases.  If enough time is given then the level of the reservoir will increase which helps in generation of the power, supplying water supply, irrigation and recreational opportunities also increases.  The Lake Powell undergoes huge evaporation and losses though seepage which decreases the amount of the stored water in reservoir which can use by human and animals.  These many deaths of boaters seen at these reservoirs due to the hypothermia and hypothermic shock caused by entering the cold water.
