 El Nino El Niño is the name given to the occasional development of warm ocean surface waters along the coast of Ecuador and Peru. When this warming occurs the usual upwelling of cold, nutrient rich deep ocean water is significantly reduced. El Niño normally occurs around Christmas and usually lasts for a few weeks to a few … Read more

 Seasonal Climatic conditions in India Climate in India varies significantly from the permanently snow-capped Himalayas in the north to the tropics in the south. The country has four seasons. December to February is relatively dry and cool, March to May is dry and hot, from June to September predominating southwest maritime winds bring … Read more

 Cyclones: Types and Mechanism Cyclone is a system of low atmospheric pressure in which the barometric gradient is steep. Cyclones represent circular fluid motion rotating in the same direction as the Earth. This means that the inward spiralling winds in a cyclone rotate anticlockwise in the Northern Hemisphere and clockwise in the Southern … Read more

 Hydrosphere – World Oceans Salinity – Ocean currents and Tides – Ocean Deposits Water is all over on Earth. About 70% of the surface of the planet is roofed by water. If you were an alien visiting the earth, you’d see a large blue sphere from area (especially on the Pacific side). Not … Read more

 Natural resources, their sustainable management and conservation A natural resource is something that is found in nature and can be used by people. Earth’s natural resources include light, air, water, plants, animals, soil, stone, minerals, and fossil fuels. People need some natural resources to stay alive. They use others to make their lives … Read more

 Pressure and wind belts Atmospheric pressure, also called barometric pressure, force per unit area exerted by an atmospheric column (that is, the entire body of air above the specified area). Atmospheric pressure can be measured with a mercury barometer (hence the commonly used synonym barometric pressure), which indicates the height of a column … Read more

 Oceans: Currents Ocean current, stream made up of horizontal and vertical components of the circulation system of ocean waters that is produced by gravity, wind friction, and water density variation in different parts of the ocean. Ocean currents are similar to winds in the atmosphere in that they transfer significant amounts of heat from … Read more
