Global Warming

  Do you know what is global warming? Well,when global warming happens, a hole is created in our ozone layer.This enables the sun's ultraviolet rays to enter Earth without being filtered.Unfiltered light rays are harmful to us and they are VERY HOT!It can cause an ice cream to melt within seconds.The hole in our ozone layer is caused mostly by carbon dioxide which rises into the atmosphere and creates a hole in the ozone layer.By the way, the ozone layer is a layer of special gas that surrounds Earth.The sun's rays are filtered by the ozone layer before they bounce off into space, keeping earth warm.However, some parts of the Earth like the North pole is further away from the sun.Therefore, it will not be able to receive enough of the sun's rays to keep it warm.That is why the North pole is most of the time cold.As the Earth rotates, soon, the North pole will be facing the sun.
