Environment of earth includes the whole of atmosphere, hydrosphere as related to biosphere. Therefore, environment includes nature, composition of air, characters of hydrological parameters, sunshine, air pressure, temperature, water resources - their storage and flow and ..

Exploration of the planets by space probes has expanded our understanding of the solar system. Modern theories about the earth's origin explore how the earth fits into the solar system, the Milky Way galaxy, and the universe as a whole. Most scientists agree that the h..

Satellite Communication - It is mainly done through geostationary satellites. These satellites are fitted with special devices. These devices can receive signals from an Earth station and transmit them again in different directions. These special devices are called transponders. A TV tran..

Geological Resources - Large number of industries is established in the course of development of human society - based on vast geological resources. Most geological resources are the basis of industrial development and improvement of human life styles. Entire mankind depends on geological sources s..

Types of Environmental Changes - Environment of earth includes the whole of atmosphere, hydrosphere as related to biosphere. Therefore, environment includes nature, composition of air, characters of hydrological parameters, sunshine, air pressure, temperature, water resources - ..

Communication Satellites - Communication satellites are normally geostationary satellites. They have devices called transponder which receive signals from an earth station and transmit them in different directions. The signals in the form of electromagnetic radiation are transmitted from ..

It is fifth most abundant element in Earth's crust. It is found existing as whole mountain ranges of limestone, marble and chalk, in vast sedimentary rocks of CaCO 3 . Other important minerals containing calcium are gypsum (CaSO 4 .2H 2 O), anhydrite (CaSO 4 ), fluorite (CaF 2 ..

Scientists who investigate weather phenomenon are called meteorologists. To study a particular feature, may require an observation from a larger area. By combining great number of observations and analysing them by computers it is possible to get information about a large weather system. Satellites..

'S' is a large spherical conducting shell of radius few meters. C 1 and C 2 are the two supporting pillars. An insulating material like silk acts like a conveyor belt wound over two pulleys P 1 and P 2 . The pulleys move with the help of a motor. B 1 and B 2 are two spray combs. D is the disc..
