Explain three ways in which human activity can reduce the time taken for water to pass through the system.
1c.[10 marks](WE HAVE NOT COVERED THIS TOPIC SECTION YET)
Examine how an international conflict has arisen as a result of competing demands for freshwater.
Award 2 marks for the correct identification of two stores (interception, surface water, soil moisture, groundwater, channel) and 2 marks for the correct identification of two transfers (soil infiltration, percolation, overland flow, throughflow, groundwater flow). No marks should be awarded for the identification of evapotranspiration or river enters the sea as a transfer.
Answers depend on the human activity/activities chosen which may lead to land use changes (urbanization, deforestation, agriculture), river channel modifications, drainage systems. Marks should not be allocated to “increased rainfall”.
Award 1 mark for correct identification of a relevant human activity and 1 mark for a valid explanation of how it reduces the time taken for water to pass through the system.
