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 Earth’s … Read more Oceans: Currents
Oceans – Bottom Relief Four major divisions can easily be identified on the ocean floor: The continental shelf, the continental slope, the continental rise, the abyssal plain. Besides these, there are many associated features—ridges, hills, seamounts, guyots, trenches, canyons, sleeps, fracture zones, island arcs, atolls, coral reefs, submerged volcanoes and sea-scarps. This great variety of … Read more Oceans – Bottom Relief
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 of mercury … Read more Pressure and wind belts
Humidity and precipitation Atmospheric humidity, which is the amount of water vapour or moisture in the air, is another leading climatic element, as is precipitation. All forms of precipitation, including drizzle, rain, snow, ice crystals, and hail, are produced as a result of the condensation of atmospheric moisture that forms clouds in which some of … Read more Humidity and precipitation
Landforms are the natural features and shapes existent on the face of the earth. Landforms possess many different physical characteristics and are spread out throughout the planet. Together, landforms constitute a specific terrain and their physical arrangement in the landscape forms what is termed as topography. The physical features of landforms include slope, elevation, rock … Read more Types of Mountains, Plateaus, Plains, Lakes
Water Resources Rainfall: With an average annual rainfall of 1,170 mm, India is one of the wettest countries in the world. At one extreme are areas like Cherrapunji, in the northeast, which is drenched each year with 11,000 mm of rainfall, and at the other extreme are places like Jaisalmer, in the west, which receives … Read more Water Resources of India
Infrastructure Development- Dams, Roads, Rails (Including Airways and Ports) The availability of efficient infrastructure services is an important determinant of the pace of market development and output growth. Historically, the infrastructure sector has been one of the key drivers of growth of the Indian economy and has shown positive growth in the current reporting year … Read more Transport : Railways, Highways, Airways and Water ways and their role in regional development, etc.
Human role in pollution control The enhanced pace of developmental activities and rapid urbanization have resulted in stress on natural resources and quality of life. The trend of increasing pollution in various environmental media is evident from the deteriorating air and water quality, higher noise levels, increasing vehicular emission etc. Realising the urgent need for … Read more Human role in pollution control, Environment and human health; Effects of pollutants on animals and plants; urbanisation and industrial development.
