Most known volcanic activity and the earthquakes occur along converging plate margins and mid-oceanic ridges. There is a strikingly close agreement between volcanic and earthquake zones of the earth. The major regions of volcanoes around the world are: Pacific ring of fire:  Pacific Ring of Fire’ is estimated to include two-thirds of the world’s volcanoes.  The major regions … Read more

The purported objective of the National Socialist Council of Nagaland-Isak-Muivah (NSCN-IM) is the establishment of a Nagalim (Greater Nagaland), consisting of all the Naga-inhabited areas of neighbouring Assam, Manipur, Arunachal Pradesh and some portions Myanmar, which it considers to be the rightful homeland of the Nagas. Slated to be an independent State, the Nagalim lies … Read more

This theory was put forth by Alfred Wegener. The continental drift hypothesis was developed in the early part of the 20th century. According to this theory, e continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. He suggested that Pangaea broke up long ago and that the continents … Read more

Irrigation should be schedule when the soil temperature is moderate. In hotter season it is better to irrigate the field during the late afternoon or at night so that both soil and plant get sufficient time to absorb water before dry and desiccating weather prevails the next day. During the very cold season water should … Read more

Transport is considered to be an important aspect in improving agricultural efficiency. It improves the quality of life of individuals, structures a market for agricultural productions, makes interaction possible among geographical as well as regions and opened up new areas to economic focus. Road transport is the most regular and multifaceted network that includes wide … Read more

The word ―monsoon‖ comes from the Arabic word mausim, meaning season. Monsoons refer to a system of winds in the tropical regions under which the direction of winds is reversed completely between the summer and the winter seasons. Under this system, the winds blow from land to sea in winter and from sea to land … 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

Crust: The outer most layer or shell of the earth is known as earth’s crust. On an average it is 30km deep. It can be up to 70km under high mountains and up to 8km under ocean. It represents less than 1% of earth’s total volume and its average density is 2.7 gm/cm3. It is … Read more

Tropical Cyclone Extra tropical cyclone It has thermal origin and derives its energy from the latent heat of condensation It has dynamic origin involving coriolis force and movement of air masses. The energy of a temperate cyclone depends on the densities of air masses. It is confined to 10o – 300 N and S of … Read more
