GREENHOUSE EFFECT Human activities are causing greenhouse gas levels in the atmosphere to increase. Solar energy is absorbed by the earth's surface, causing the earth to warm and to emit infrared radiation. The greenhouse gases then trap the infrared radiation, thus warming the atmosphere. This is called GLOBAL WARMING.
The hole is caused by different gases resulting from human-produced chemicals, such as chlorofluorocarbons (CFCs) used in air-conditioners, refrigerators… OZONE LAYER The ozone layer blocks 90-99% of the sun's harmful ultraviolet radiation, which causes skin cancer, genetic damage, and eye damage, and is harmful to marine life.
