Einstein’s general theory of relativity predicts that gravitating mass could collapse under its own gravitation into a ‘singularity’ of infinite density. Such a superdense ‘singularity’ or black hole traps inside itself all radiation so that it cannot be seen even Read more…


The insatiable desire of mankind to alter the environment to suit its own need has often done untold damage to the environment. This is partly due to negligence. The Dal Lake recently would have almost ceased to be as it Read more…


A very small amount of nuclear fuel generates wastes when put through the fusion pro­cess. Since the half life periods of these wastes are much much longer compared to human time scale, they have a potential to emit radiation for Read more…


ALL the living processes on earth are guided and control­led by the sun – the ultimate limitless source of energy. But since the advent of mankind on earth, the need to change the natural environment has been felt. The insatiable Read more…


The atmosphere was not present when the Earth took its birth some 4.5 b. y. ago. Earth’s original atmosphere probably formed along with the planet. Scientists theorise that the Sun and all the planets formed from a cloud of gas Read more…


The theory of plate tectonics explains the Earth’s crustal dynamics by the movement of rigid lithospheric plates. Each plate is part of a shell on a sphere, so different parts of the plate move at different velocities. The direction of Read more…


Pseudo volcanic features are certain topographic features that resembles volcanic forms but are of non-volcanic origin. They include Meteorite crater, Salt plugs, and Mud volcanoes? Craters Crater is an abrupt circular depression formed by extrusion of volcanic material, by collapse, Read more…


Most forms of condensation in the atmosphere result from the air being cooled in some way or the other. Condensation near the ground results from contact cooling, advection cooling and radiation cooling. A number of weather phenomena result from condensation Read more…


Tropical cyclones called as Hurricanes in Caribbean and Central America, Typhoonsin South China Sea, Cyclones in Bay of Bengal are not only confine to these arear. They also occur South of Japan called Taifu, in Phillipines called as Baguio, and in Australia as Willy Willies) Tropical cyclone form Read more…
