4. in several parts of the world there exist ocean currents of differing temperature that come into contact. an example of this takes place off the coast of southern africa, where the warm agulhas and the cold benguela currents meet at cape point, near capetown. it has been proposed that work may be obtained from these ocean currents if heat engine could operate between the warm current as a source and the cold current as a sink. assume that the system may be simplified into two channels of water flowing concurrently on either side of power plant with no heat losses to the surrounding water. it has been estimated that the benguela current flows at the rate of 16 million m3/s and its initial temperature is 40ď‚°f. the agulhas flows at 20 million m3/s and its initial temperature is 80ď‚°f. calculate the maximum power available from these two currents

Which of these statements best explains how the hydrosphere interacts with the atmosphere to affect global climate? mountains block rain clouds and cause changes in global rainfall and evaporation. humans burn fossil fuels to produce greenhouse gases which cause global warming. humans cut down trees which affects the amount of oxygen in different parts of the globe. greenhouse gases, like carbon dioxide, dissolve in oceans and prevent global warming.
