Overconsumption The energy crisis is a result of many different strains on our natural resources, not just one. There is a strain on fossil fuels such as oil, gas and coal due to overconsumption – which then in turn can put a strain on our water and oxygen resources by causing pollution. Overpopulation Another cause … Read more

Tsunami meaning “harbour wave” It is a series of extremely long waves caused by a large and sudden displacement of the ocean due to earthquake, volcanic eruptions etc. When they reach the coast, they can cause dangerous coastal flooding and powerful currents that can last for several hours or days. Characters of Tsunami waves are … Read more

The study of temperature of the ocean is important for studying the movement of large volumes of water, distribution of marine organisms, other properties such as salinity. This distribution pattern can be studied under vertical and horizontal distribution. Factors responsible for variation in horizontal distribution: The average temperature of surface water of the ocean is … Read more

When two large air masses meet, the boundary that separates them is called a front. Fronts represent fairly abrupt transitions between two large air masses.  This means that when two different bodies of air come together, they do not readily mix. Rather, each body of air will retain its individual properties, and a boundary forms … Read more

Diastrophism refers to deformation of the Earth’s crust due to diastrophic movements (deforming movements) such as folding, faulting, warping (bending or twisting of a large area) and fracturing. All processes that move, elevate or build up portions of the earth’s crust come under diastrophism.  They include: orogenic processes involving mountain building through severe folding (crust is severely deformed into folds) and affecting long … Read more

A glance at the world map reveals that most of the desert region is on the western part of the continent for example. Mohave desert in North America, Atacama in Southern America, Namib, Sahara in Africa , Arabian in west Asia. The reasons for such homogeny are: The hot desert lie astride the Horse latitudesor … Read more

Runs through the states of … Read more

  The cost of recharge to sub-surface reservoir is lower than surface reservoirs. The aquifer serves as a distribution system also. No land is wasted for storage purpose and no population displacement is involved. Ground water is not directly exposed to evaporation and pollution. Storing water under ground is environment friendly. It increases the productivity … Read more
