India’s Population Profile
Published: Nov 30, 2011
Abstract: According to the provisional Census figures, although decadal growth in India’s population has registered the sharpest decline during 2001-2011, in terms of absolute numbers the population has increased by more than 181 million over the decade. India today sustains 17.5 per cent of the world population in 2.4 per cent of its geographical area.

The Pangaea theory states that all present continents were once together and collectively called a ‘supercontinent Pangaea. The split up pieces slowly drifted apart and took the shape that we now see. Even now, the surface of the Earth is constantly undergoing changes.
The artificial modification of Earth systems to counteract the effect of man’s actions on nature such as increasing CO2 uptake by fertilising the ocean surface waters and screening out sunlight with orbiting mirrors. It is also known as climate engineering and climate remediation.
Transuranic elements are elements with an atomic number that is greater than 92. These elements are not stable and undergo radioactive reactions to form other elements. They are artificially manufactured in the lab by nuclear processes and by using particle accelerators.
A geological term used to refer to the state of gravitational equilibrium between the Earth’s lithosphere and asthenosphere in such a way that the tectonic plates float at an elevation which depends on their thickness and density. It explains the different topographical features present on the Earth’s surface.
The inverse of geoengineering, anthropogenic degradation is the environmental degradation caused by humans and their activities. These include all kinds of pollution caused by industries, farming and our day to day activities. Some people believe that pollution itself is only anthropogenic.
The development and strengthening of cyclonic circulation in the atmosphere. Cyclogenesis is an umbrella term for several different processes, all of which culminate in the formation of some sort of cyclone. It can occur at scales varying from the microscopic to the synoptic.
A wet underground layer of water bearing permeable rock or unconsolidated materials such as gravel, sand and silt. The rocks contain water-filled pores which allow water to flow through their matrix. Groundwater can be usefully extracted from this layer using water wells.
A suspension of fine solid particles or liquid droplets in a gas such as clouds, smog and smoke. The solid and liquid particles can remain suspended in air from a few minutes to a few months depending on particle size and weight.
It is the measure of the ignition quality of petrol or gasoline. The higher the octane number the less susceptible the gas is to premature burning in the combustion chamber. It denotes the percentage by volume of iso-octane in a combustible mixture.
It is a climate pattern that occurs across the tropical Pacific Ocean roughly every five years. It is characterised by variations in the temperature of the surface of the tropical eastern Pacific Ocean and air surface pressure in the tropical western Pacific.
An organism capable of synthesising its own food from inorganic compounds. Autotrophs produce their own sugars, lipids, and amino acids and are hence producers in the food chain. They do not use organic compounds to derive energy. Examples are plants and algae.
The Revelle Factor enables us to measure the resistance to atmospheric CO2 being absorbed by the ocean surface layer. The capacity of ocean water to take up surplus CO2 is inversely proportional to the value of the calculated Revelle Factor.
