Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy

That depends. cause the owl finished it in one lick

Use a magnet to separate iron, evaporate water, i'm not sure how to separate the other two i'm sorry but good luck
