Weaker and Weaker

Artificial substances are destroying the ozone layer, which provides protection against ultraviolet rays. This phenomenon is observed every year in polar regions (primarily in the Antarctic) between August and October. Because of this, the Earth is receiving more harmful rays, which perhaps explains the appearance of certain illnesses an increase in skin cancer cases, damage to vision, and weakening of the immune system. 11,000,000 square miles (28,000,000 sq km) 10,000,000 square miles...

The Effects of El

The natural warm phenomenon known as El Ni o alters the temperature of the water within the east central zone of the Pacific Ocean along the coasts of Ecuador and Peru. Farmers and fishermen are negatively affected by these changes in temperature and the modification of marine currents. The nutrients normally present in the ocean decrease or disappear from along the coast because of the increase in temperature. As the entire food chain deteriorates, other species also suffer the effects and...

Lost in the

When atmospheric water vapor condenses near the ground, it forms fog and mist. The fog consists of small droplets of water mixed with smoke and dust particles. Physically the fog is a cloud, but the difference between the two lies in their formation. A cloud develops when the air rises and cools, whereas fog forms when the air is in contact with the ground, which cools it and condenses the water vapor. The atmospheric phenomenon of fog decreases visibility to distances of less than 1 mile (1.6...

What Is Cfc And Ci Ozone Layer

1 Ultraviolet radiation strikes a molecule of CFC gas. CFC GASES are a family of gases with multiple applications. They are used in refrigeration systems, air-conditioning equipment, and aerosols. In 1974, it was discovered that industrial chlorofluorocarbons (CFCs) affect the ozone layer. Chemists Mario Molina and F. Sherwood Rowland demonstrated that industrial CFCs are the gases that weaken the ozone layer by destroying the ozone molecules. Ultraviolet radiation (UV) is a radiant form of...
