The most important and most neglected part for Civil Services Preparation is answer writing. It is not about HOW MUCH YOU STUDY but CAN YOU WRITE within word limit and time frame. After UPPCS daily answer writing practice, ORACLE IAS comes out with new initiative UKPCS DAILY ANSWER WRITING PRACTICE.
1.Explain the phenomena of monsoon in the subcontinent (125 words)
भारतीय उपमहाद्वीप में मानसून की घटना को समझाएं|
2.What is a fault? Explain different types of faults how are faults and earthquake linked? (250 words)
भ्रंश क्या है ? विभिन्न प्रकार के भ्रंश को समझाएं भूकंप और भ्रंश में क्या संबंध है?
- The following facts are important to understand the mechanism of Indian monsoon:
Differential Heating and Cooling of Land and Water
- Due to this lower pressure is found on the landmass.
- High pressure is found on the water bodies/seas and oceans around India.
Shift in the position of Inter Tropical Convergence Zone (ITCZ)
During summer it shifts its position to the Ganga plain, and is also known as monsoon trough, during the monsoon season.
Presence of High Pressure Area, East of Madagascar (Indian Ocean Dipole)
The intensity and position of this high pressure area affects the Indian monsoon.
Intensely Heated Tibetan Plateau
It results in the strong vertical currents that affect the monsoons.
Westerly Jet Stream and Tropical Easterly Jet Stream
Westerly Jet stream moves to the north of the Himalayas while easterly jet stream is present over the Indian Peninsula.
Southern Oscillation and El Nino
Changes in the pressure conditions over the southern oceans also affect monsoons. It has been seen during El Nino years monsoon is deficient in India while during La Nina it is more than normal.
- Faults are fractures in Earth’s crust where rocks on either side of the crack have slid past each other. Sometimes the cracks are tiny, as thin as hair, with barely noticeable movement between the rock layers. But faults can also be hundreds of miles long.
Types of faults
Strike-slip faults indicate rocks are sliding past each other horizontally, with little to no vertical movement. Both the San Andreas and Anatolian Faults are strike-slip.
Normal faults create space. Two blocks of crust pull apart, stretching the crust into a valley. The Basin and Range Province in North America and the East African Rift Zone are two well-known regions where normal faults are spreading apart Earth’s crust.
Reverse faults, also called thrust faults, slide one block of crust on top of another. These faults are commonly found in collisions zones, where tectonic plates push up mountain ranges such as the Himalayas and the Rocky Mountains.
Strike-slip faults are usually vertical, while normal and reverse faults are often at an angle to the surface of the Earth.
All faults are related to the movement of Earth’s tectonic plates. The biggest faults mark the boundary between two plates. Individual fault lines are usually narrower than their length or depth. Most earthquakes strike less than 50 miles (80 kilometers) below the Earth’s surface. The deepest earthquakes occur on reverse faults at about 375 miles (600 km) below the surface. Below these depths, rocks are probably too warm for faults to generate enough friction to create earthquakes.
