Precipitation over Equatorial east Africa is quite different from that over other equatorial regions. East Africa itself, along with Somalian coast, is an area of low rainfall and is almost arid in some parts. Thus, the most notable characteristic of Read more…


Shale Gas is a form of natural gas that is trapped within shale (a fine grained sedimentary rock) formations, shale gas is known for more than a century. It was not seen as a viable alternative to petroleum fuels because Read more…


Ever since human beings first settled in the polar regions they have been awed by the glowing lights-towering, rippling multicoloured curtains of light that often hang above many cities lying in the polar regions-Fairbank in Alaska, parts of uninhabitable Greenland Read more…


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…
