Carbon Dioxide (CO2) (n) Fossil fuels(n) (coal, oil, natural gas) How Global Warming(n) Works(v)
Example of the Greenhouse Effect(n) The Sun’s(n) energy passes(v) through the car’s windshield(n). This energy (heat) is trapped(v) inside the car and cannot pass(v) back through the windshield(n), causing(v) the inside(n) of the car(n) to warm up(v).
