Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. Solar panels actually comprise many, smaller units called photovoltaic cells. (Photovoltaic simply means they convert sunlight into electricity.)
Human activities cause increased nitrogen deposition in a variety of ways, including
<span>burning of both fossil fuels and forests, which releases nitrogen into the atmosphere
fertilizing crops with nitrogen-based fertilizers, which then enter the soil and water
ranching, during which livestock waste releases ammonia into the soil and water
<span>allowing sewage and septic tanks to leach into streams, rivers, and groundwater</span></span>
