 1. Hydrological Cycle: The sequence of conditions through which water passes from vapor in the atmosphere through precipitation upon land or water surfaces and ultimately back into the atmosphere as a result of evaporation and transpiration --called 'hydrological cycle'.


2. Scarcity: The state of being scarce or in short supply; shortage.


3. Conservation: The protection of plants and animals, natural areas and interesting and important buildings especially from the damaging effects of human activity.


4. Non-renewable Resources is a resource of economic value that cannot be readily replaced by natural means on a level equal to its consumption.


5. Groundwater: Water held underground in the soil or in pores and crevices in rock.


6. Hydroelectric Power: A form of energy generated by the conversion of free-falling water to electricity; the generation of electricity by using the motive power of water; also called hydroelectricity.


7. Archaeology: The study of human history and prehistory through the excavation of sites and the analysis of artefacts and other physical remains.


9. Dams: A barrier constructed to hold back water and raise its level, forming a reservoir used to generate electricity or as a water supply8. River Basin: The area of land drained by a river and its branches.



10. Industrialisation: The development of industries in a country or region on a wide scale.


11. Sedimentation: The process of settling or being deposited as a sediment.


12. Reservoirs: A large natural or artificial lake used as a source of water supply


13. Decomposition: The state or process of rotting; decay.


14. Flood Plains: An area of low-lying ground adjacent to a river, formed mainly of river sediments and subject to flooding.


15. Irrigation: The supply of water to land or crops to help growth, typically by means of channels.


16. Rainwater Harvesting: The harvesting of rainwater simply involves the collection of water from surfaces on which rain falls, and subsequently storing this water for later use.

Normally water is collected from the roofs of buildings and stored in rainwater tanks


17. Soil Erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing of a field's topsoil by the natural physical forces of water and wind or through forces associated with farming activities such as tillage.


18. Roof top Rainwater Harvesting: Rainwater harvesting is the technique through which rain water is captured from the roof catchments and stored in reservoirs.

Questions from potentiometer

  Potentiometer Questions from potentiometer Q1. Why is a potentiometer preferred over a voltmeter for measuring the emf of a cell? Ans. Potentiometer work on null method, It does not draw any current from the cell thus there there is no potential drop due to the internal resistance of the cell. It measures the potential difference in an open circuit which is equal to the actual EMF of the cell. It is very accurate device. On the other hand, voltmeter draw small current from the cell for its operation. So it measures terminal potential difference in a closed circuit which is less than EMF of the cell Q2. The sensitivity of a potentiometer increases with increase in length of its wire. Explain why? Ans. When the length of the wire increases the fall of potential per unit length of the wire become smaller (i.e potential gradient K= V/L ). Hence even a small potential difference can be measured. Q3. Sometime the balance point in the potentiometer may not be obtained on the wire ...
