Global Warming
The addition of certain pollutants like the carbon dioxide gases increases the temperature of the earth. These gases remain close to the surface of earth, forming an insulating layer. The surface becomes hot due to the solar radiations. This radiation is normally reflected back..

We often hear that an astronaut experiences weightlessness in space. What does this mean? Let us perform a simple experiment to demonstrate weightlessness. Suspend a stone from a spring balance, the pointer of the spring balance shows the weight of the stone. Allow the spring balance alon..

Solar energy is responsible for the blowing of wind. The intensity of sun-rays is stronger near the Equator than at the Polar Regions. Due to unequal heating of the earth's surface, cooler air from the Polar Regions flow towards the equatorial regions to fill the space created..
