It is a belt of low pressure which circles the Earth generally near the equator where the trade winds of the Northern and Southern Hemispheres come together. It is characterised by convective activity which generates often vigorous thunderstorms over large areas. It is most active over continental land masses by day and relatively less active … Read more

The 2011 Census is the first one in many decades which counted less absolute number of children in the 0-6 age group. Compared to 2001 Census count of 164 million children, there were 159 million children in 2011, or there were 5 million fewer children in India. This is evident in the share of children … Read more

Environmental Consequences One of the primary disadvantages of hydroelectric energy is its potential to destroy ecosystems. Plant and animal life in rivers and streams depends on certain environmental factors, from the speed at which the water flows, the level of water in the river bed, and the temperature of the water to the exact mix … Read more

. The trade winds, westerly and easterlies  are the permanent winds. These blow constantly throughout the year in a particular  direction and they are global in nature.  These play an important role in, and in turn get influenced too, formation of Weather  Cell. Headly Cell The air at the Inter Tropical Convergence Zone (ITCZ) rises … Read more

Temperate cyclones are also known as Extra-tropical cyclone where the term “Extra-tropical” signifies that this type of cyclone generally occurs outside the tropics with a latitude range between 30° and 60°. Characteristics of Temperate Cyclone (Extra-Tropical Cyclones) The Extra-Tropical Cyclones are storm systems emerging in the mid and high latitudes, away from the tropics. They … Read more

The continental drift hypothesis was developed in the early part of the 20th century, mostly by Alfred Wegener. Wegener said that continents move around on Earth’s surface and that they were once joined together as a single supercontinent. While Wegener was alive, scientists did not believe that the continents could move. Alfred Wegener proposed that … Read more

 Unlike durable crops such as cereals, pulses and oilseeds, fresh fruits and vegetables are highly perishable, and must be marketed immediately after harvesting without primary processing. Fruit and vegetables generate large quantities of valuable waste that ends up as garbage.  However, if they are gainfully utilized at the proper time they can become … Read more

The following factors affect the distribution of temperature of ocean water: Latitudes The temperature of surface water decreases from equator towards the poles because the sun’s rays become more and more slanting and thus the amount of insolation decreases poleward accordingly. The temperature of surface water between 40°N and 40°S is lower than air temperature … Read more

There are several reasons for this. First, the mountain topography in Karnataka is broader than the narrow topography of the Ghats in Maharashtra. Due to the greater width of the mountains, the rain bearing winds have to necessarily travel a longer distance and have more time for the drops to coalesce and precipitate as rainfall, … Read more
