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
Flood is a natural disaster which can never be avoided, India being one of the worst flood hit tropical country in the world which causes huge economic and emotional losses. We cannot afford to ignore flood but we can manage it. Around 12% of the total area i.e. 40 million hectare is prone to flood. … Read more
Coal bed methane is found in the impermeable stone and is trapped in the coal seams. A significant portion of this gas remain as free gas in the joints and fractures of the coal seam. Large quantities of gas are adsorbed on the internal surfaces of the micropores within the coal itself Coal bed methane … Read more
The wind blows from high pressure to low pressure. The wind at the surface experiences friction. In addition, rotation of the earth also affects the wind movement. The force exerted by the rotation of the earth is known as the Coriolis force. Thus, the horizontal winds near the earth surface respond to the combined effect … Read more
Some air movements are the result of the systematic pressure gradients that arise from latitudinal changes in the Earth’s surface temperature. One notable example is the Hadley Cell, a movement of warm air from the tropics that rises, flows toward the poles and then cools and sinks at around 30 degrees north and south of … Read more
Poverty Poverty is one of the foremost problems faced by India for ages. Poverty becomes a root cause of the widespread illiteracy in India. Families who struggle for their daily bread cannot afford education for their children. Apparently these people tend to make their children work to cope with the financial problems. Lack of School … Read more
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane, tropicalstorm, cyclonic storm, tropical depression, and simply cyclone.Tropical cyclones are named to provide ease of communication between forecasters and the … Read more
Fold Mountains are commonly associated with continental crust. They are formed due to convergence between two continental plates or between an oceanic and a continental plate. This convergence happens at the convergent plate boundaries, also called as continental collision zones or compression zones. The convergence of two continental plates causes sediments between them to get … Read more
The main reasons for concentration of jute industries in WB are: Favourable condition for Jute production: Ample amount of water, high humidity and warm and wet climate. Secondly cheap labour is also available from Bihar, West Bengal, Odisha etc Hubly river also provide import and export of jute. Problem faced by Jute industry: Shortage of … Read more
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
