The earth is made up of several concentric layers of varying density and composition. Broadly, threezones can be identified on the basis of changes in the velocity of seismic waves while passing through theearth as below – Core:The Core is further divided into two sub-zones – outer core and inner core. The outer core is … Read more

. The El Nino-Southern Oscillation (ENSO) is an irregular cycle of change in wind and sea surface temperatures over the tropical eastern Pacific Ocean, affecting the climate of much of the tropics and subtropics. The warming phase of the sea temperature is known as El Nino and the cooling phase as La Nina. This sea … Read more

The Inter Tropical  Convergence Zone (ITCZ) or Thermal Equator is a broad trough of low pressure in  equatorial latitudes (it always remains on the north of the equator due to effect of  landmass). This is where the northeast and the southeast trade winds converge and this  is a low pressure zone. This convergence zone lies … Read more

They can be of various types depending upon the process of precipitation,  obstacles etc. Convectional Rain The, air on being heated, becomes light and rises up in convection  currents. As it rises, it expands and loses heat and consequently, condensation takes  place and cumulous clouds are formed. With thunder and lightening, heavy rainfall  takes place … Read more

.  Process of formation of the fronts is known as frontogenesis. There are four types of fronts: Cold Front When the cold air moves towards the warm air mass, its contact zone is  called the cold front. As the cold front nears your region, the barometer falls.  The cold  air behind the front wedges under … 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

. Most of the metallic minerals in India occur in the peninsular plateau region in the old  crystalline rocks. Over 97 per cent of coal reserves occur in the valleys of Damodar, Sone, Mahanadi and Godavari.  Areas of high rainfall lack in soluble minerals like Limestone, Gypsum and Salt.  Northern Plains are poor in minerals … Read more
