DMPQ- Explain the concept and significance of plate tectonic theory .

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- Discuss the pre-disaster preventive measures and post-disaster preventive measures in case of Earthquake.

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- Briefly explain the process of weathering.

. 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- Throw light on the intrusive volcanic landforms.

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- Discuss the different aspects of winter weather in India.

. 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
