Biosphere - Earth is the only planet on which life exists. It consists of three components Lithosphere (Land), Hydrosphere (Water) and Atmosphere (Air). Life originated and evolved because of this unique combination of the three components and was ideal and favourable for life. The life supporting ..

Boric anhydride reacts with certain metal salts such as, Ni 2 + , Co 2 + , Cr 3 + , Cu 2 + , Mn 2 + etc. to form colored metaborates. The color of the metaborates is used to identify the metallic ion (cation) in the salt. Taking a small quantity of borax on a small loop of platinum wire to p..

Topography includes the physical features of the earth like altitude, slope, exposure, mountain chains, valleys, plains, etc...

. The changes that occur from time to time can also be monitored. (5) Remote sensing can also provide data related to ocean and coastal zones: The potential area of fish concentration can be identified. Environmental degradation that takes place in coastal zones due to overexplo..

During the formation of the Earth, cooling of gaseous mixtures took place and molten earth condensed to form different earth zones or layers. Each layer that formed on top of the other had a definite chemical composition and thus a distinct distribution of elements within it. The innermo..

All the ecosystems of the world together form the biosphere. It consists of all the living organisms and all the regions of the earth and its atmosphere where they live. A Biome is a large unit characterised by flora and fauna found in a specific climatic zone. For e.g., a desert or a tr..

>Cultivation of agro-climatic zones is determined by water requirement of crops. The scope of the chapter in real life applications: Turgidity plays an important role in plants. So wilting can be remedied by watering. Anti-transpirant spray reduces the rate of transpiration. The use of an..

. (ii) for heavy nuclei (A > 20) the n/p ratio increases progressively due to dominance of number of neutrons. Thus stable nuclei (non-radioactive) have n/p ratio between 1 - 1.6. These lie in the shaded region of the plot which is also called stability belt or stability zone. The element..

. There are some worrying facts about the water situation. The effects of world climate change are being all over including the Indian subcontinent. The increased temperature levels are resulting in changing weather patterns. For a country like India whose agricultural activities (and water infrast..
