Main causes of the earthquake are plate tectonics, volcaniceruption or anthropogenic activities like explosions, reservoir induced seismicity etc. There is arelease of huge amount of energy in the form of sound and seismic waves causing shaking of earth’s surface. The regions which are on the  boundaries of the tectonic plates are more prone to earthquake.  … Read more

Hydropower is a renewable energy resource because it uses the Earth’s water cycle to generate electricity. Water evaporates from the Earth’s surface, forms clouds, precipitates back to earth, and flows toward the ocean. The movement of water as it flows downstream creates kinetic energy that can be converted into electricity. 2700 TWH is generated every … Read more

Seismic waves are generated due to the release of the energy during an earthquake. They behave differently in different physical mediums and hence provide a good idea how the interior of earth must be. Broadly there are three types of seismic waves: Primary waves: (P) – Waves are longitudinal waves. i.e. The motion of particles … Read more

Negatives of Interlinking of rivers: This entails environmental cost. Interlinking would destroy water bodies as each river has unique flora and fauna based on its ecology. Mixing of waters will adversely affect this uniqueness, producing unforeseen consequences. Interlinking will lead to submergence of forest. This will worsen climate change. Forest, which act as carbon sinks … Read more

Tropical Monsoon Tropical monsoon climates are most found in southern Asia and West Africa. A monsoon is a wind system that reverses its direction every six months. Monsoons usually flow from sea to land in the summer, and from land to sea in the winter. Summer monsoons bring large amounts of rainfall to tropical monsoon … 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

A tsunami is a wave, or series of waves, caused by the vertical displacement of a column of water. This can be generated by earthquakes below the sea floor and violent volcanic eruptions above it, landslides above or below water or meteorite impacts into the sea. Effects of Tsunami: Affecting the mangroves, wetlands and basically … Read more

Critical infrastructure is a term used by the governments to describe assets that are essential for the functioning of a society and economy.  The term Critical infrastructure has been widely adopted to distinguish those infrastructure elements that, if significantly damaged or destroyed, would cause serious disruptions of the dependent system or organisation.   Storm, deluge … Read more

Rainwater harvesting is the process to capture and store rainfall for its efficient utilization and conservation to control its runoff, evaporation and seepage. Some of the benefits of rainwater harvesting are: It increases water availability It checks the declining water table It is environmentally friendly It improves the quality of groundwater through dilution, mainly of … Read more

India is the second populous country after china. India has 17.74% of the total world population. The main reason for the high population growth is the high fertility rate which is presently 2.5. It means an Indian women in her reproductive span produces 2.5 offspring on an average. The reasons for high fertility rate are … Read more
