Soil is a layer produced by the gradual weathering of the rock and covers the upper most surface. Development of soil depends on the several factors like Climate, Time, Topography, Parent rock, Biological activity etc. The soil profile is the sequence of soil material found in the vertical section. read more about soil and soil […]

Richardson number that is also called the mixing efficiency of stratified turbulence. It is important in determining the flows like ocean circulation, air-sea transport or air turbulence. A lower value indicates a higher degree of turbulence. Flux Richardson Number In a static stable environment, turbulent vertical motions are acting against the restoring force of gravity.

Planation surface is a large surface that is flat or near flat with possible exception of some residual hills. The process by which planation surface are formed collectively called as planation and are exogenic in nature. There are many planation surfaces based on their mode of development : Peneplain (Devis) Pediplain (L.C. King), Panplain (Crickmay),

Sand dunes are the build up of sand formed due to water or wind process under the influence of gravity. It typically takes the shape of a ridge, mound or hill that far from the tidal influence. The area which is associated with the dunes is called dune system or dune complex. A collection of

As we know that the Himalayan range which extends over ~2400 km have the largest glacial cover after the Polar regions and also it is highly sensitive. This region is also called as “Water Tower of the world”. The study of these glaciers is also important as it contributes to the major rivers like, Indus,

The force which opposes the relative motion of any body which is in contact with another body is called friction. Amount of friction can be different that depends on the movement of the body as follows : Key Factors – There are two different type of friction can be classified based on the kind of
There are several types of geological formations that trap naturally occurring energy resource. They are categorized as either ‘conventional’ or ‘unconventional’ resources. Conventional Unconventional Conventional oil and gas is trapped in naturally porous reservoir formations that are capped with impermeable rock strata. When intercepted by a well, oil and gas is able to move to

Ocean is much more deeper than the elevation of the land area on the continent. As you can imagine that the highest point in the continent is around 8800m from the mean sea level while the deepest part of the ocean is 11000m deep from the mean sea level. This deep and thick water column

Mantle subdivision : In the PREM seismic model, the boundary between the upper mantle and the lower mantle is accepted at a depth of 670km, where seismic velocities and density increases. This discontinuity is related to the transition of olivine from the ringwoodite phase into the mixture of perovskite and mangnesiowustite. In the Pyrolite model,
