Some scientists believe that the earth began billions of years ago as a huge ball of swirling dust and gases. If you dig in your backyard, don’t worry about running into the earth’s core. You’d have to dig a hole 4,000 miles (6,437 kilometers) deep!

-- How the wind blows. As the sun warms the earth’s surface, the atmosphere warms too. Some parts of the earth receive direct rays from the sun all year and are always warm. Other places receive indirect rays, so the climate is colder. Warm air, which weighs less than cool air, rises. Then cool air moves in and replaces the rising warm air. This movement of air is what makes the wind blow.
- Dolphins sleep with one eye open!
--Why do we might feel warmer wearing a dark-colored jacket than a light-colored one? . Dark colors absorb light energy. Light colors and white reflect light energy. When light shines on your dark jacket, the jacket fabric absorbs light energy. The absorbed light energy causes electrons in the atoms of the jacket to vibrate. This activity releases heat energy, which makes the jacket—and you—warmer. That's why we like to wear more dark colors in winter and more light colors in summer.

The Industrial Revolution in Europe first saw the beginning of air pollution, which gradually became a major global problem.
The major air-polluting industries are iron, steel and, cement.
Of the 35-40 million tonnes of flyash generated annually by thermal power plants in India, only 2-3 percent is productively utilized.
The worst industrial disaster in India, occurred in 1984 in Bhopal the capital of Madhya Pradesh. A deadly chemical, methly isocyanate leaked out of the Union Carbide factory killing more than 2500 and leaving thousands sick. In fact the effects of this gas tragedy is being felt even today.
Every year some 50million cars are added to the world’s roads. Car making is now the largest manufacturing industry in the world.
In India the number of motorized vehicles have increased from 0.2 million in 1947 to 36.3 million in 1997.
The number of registered vehicles in Delhi is more than the sum total of registered vehicles in Mumbai, Calcutta, and Chennai.
Major contributor to Delhi's air pollution are vehicles.
Nearly three-fourths of India's population, which is rural, bears 84% of the burden of exposure to air pollution.
Growing population, poverty, and inadequate access to clean fuels in rural areas have perpetuated the use of biomass, thereby condemning more than 90% of rural households and more than 35% of urban hoseholds to high levels of indoor air pollution.
One of the most important measure to counter pollution is planting trees. With neem and peepal being the largest emitters of oxygen, planting them in the gardens purifies the surrounding air and helps in maintaining hygienic conditions. While champa, mogra and chameli have better chances of surviving pollution in summer, bulbous varieties do better in winter.
