The theory of plate tectonics proposes that the earth’s lithosphere is divided into seven major and several minor plates. The movement of the plates results in the building up of stresses within the plates and the continental rocks above, which leads to folding, faulting and volcanic activity. The major plates are surrounded by fold mountains, … Read more DMPQ- Explain the concept and significance of plate tectonic theory .

Droughts and floods are the two accompanying features of Indian climate. According to some estimates, nearly 19 per cent of the total geographical area of the country and 12 percent of its total population suffer due to drought every year. About 30 percent of the country’s total area is identified as drought prone. Extreme Drought … Read more DMPQ- Map out the draught prone areas in India. Also mention the Institutional mechanism for draught management in India.

Monsoon is that axis around which revolves the entire agricultural cycle of India. It is because about 64 per cent people of India depend on agriculture for their livelihood and agriculture itself is based on southwest monsoon. Except Himalayas all the parts of the country have temperature above the threashold level to grow the crops … Read more DMPQ- Explain the relationship between monsoon and economic life in India.

Pre-disaster preventive measures Re-framing buildings’ codes, guidelines, manuals and byelaws and their strict implementation .Tougher legislation for highly seismic areas. Incorporating earthquake resistant features in all buildings in high-risk areas. Making all public utilities like water supply systems, communication networks, electricity lines, earthquake-proof. Creating alternative arrangements to reduce damages to infrastructure facilities. Constructing earthquake-resistant community … Read more DMPQ- Discuss the pre-disaster preventive measures and post-disaster preventive measures in case of Earthquake.

Most of our knowledge about the interior of the earth is largely based on estimates and inferences. Yet, a part of the information is obtained through direct observations and analysis of materials. The most easily available solid earth material is surface rock or the rocks we get from mining areas. Gold mines in South Africa … Read more DMPQ- . Briefly discuss the direct sources of information about the interior part of earth.

. The temperature of air at any place is influenced by : The latitude of the place; The altitude of the place; distance from the sea, the airmass circulation; The presence of warm and cold ocean currents; Local aspects.   The latitude The temperature of a place depends on the insolation received. It has been … Read more DMPQ- What are the factors that control temperature distribution on the surface of the earth?

. Weathering processes are responsible for breaking down the rocks into smaller fragments and preparing the way for formation of not only regolith and soils, but also erosion and mass movements. Biomes and biodiversity is basically a result of forests (vegetation) and forests depend upon the depth of weathering mantles. Erosion cannot be significant if … Read more DMPQ- Briefly explain the process of weathering.

Batholiths A large body of magmatic material that cools in the deeper depth of the crust develops in the form of large domes. They appear on the surface only after the denudational processes remove the overlying materials. They cover large areas, and at times, assume depth that may be several km. These are granitic bodies. … Read more DMPQ- Throw light on the intrusive volcanic landforms.

. In winter months, the weather conditions over India are generally influenced by the distribution of pressure in Central and Western Asia. A high pressure centre in the region lying to the north of the Himalayas develops during winter. This centre of high pressure gives rise to the flow of air at the low level … Read more DMPQ- Discuss the different aspects of winter weather in India.

The Matching of Continents (Jig-Saw-Fit) The shorelines of Africa and South America facing each other have a remarkable and unmistakable match. It may be noted that a map produced using a computer programme to find the best fit of the Atlantic margin was presented by Bullard in 1964. It proved to be quite perfect. The … Read more DMPQ- . Discuss the evidences in support of Continental drift theory.
