WHAT IS THE GREENHOUSE EFFECT?






                    In the atmosphere, there are gases which are good at trapping the


                    heat reflected from Earth. They keep Earth warm just like glass on

                    the greenhouse keeps the warmth inside.



                    Without these gases, Earth would be freezing with an average


                    temperature of around –19 °C instead of +15°C and would suffer


                    from such extreme temperatures that it could not support life.






                                                   These gasses are called greenhouse gases and the


                                                   effect of these gases keeping the earth warm is the

                                                   greenhouse effect.
