Syntaxial Bends: The Himalayan mountain range exhibits two major syntaxial bends — the Western (near the Indus gorge) and the Eastern (near the Tsangpo/Zangbo gorge).
Kashmir Valley: A large intermontane valley located between the Pir Panjal Range and the Zaskar Range.
**Fluvial Indicators:*

- Brahmaputra Basin: Covers parts of China (Tibet), India, Bhutan, and Bangladesh.
Peninsular Rivers: Consequent, seasonal (rain-fed), mature stage (broad valleys, graded profiles). Flow largely west to east (Mahanadi, Godavari, Krishna, Cauvery) forming deltas, except Narmada and Tapi (flowing west in rift valleys forming estuaries).
**River Origins (Himachal Pradesh):*
- Beas: Originates from Beas Kund near the Rohtang Pass.
- Ravi: Originates from the Kullu Hills (near Rohtang Pass).
- Chenab: Formed by the confluence of the Chandra and Bhaga rivers at Tandi.
- Mahanadi: Does not originate from the Himalayas.
- Decreasing length: Godavari > Krishna > Mahanadi > Kaveri.
Water Divides: The Great Water Divide separating Arabian Sea drainage (23%) from Bay of Bengal drainage (77%).
River Basin Percentages: (of total geographical area of India)
- Ganga: 25.2%
- Godavari: 9.5%
- Krishna: 7.9%
- Mahanadi: 4.3%
**National Waterways (NW):*
- NW 1: Allahabad to Haldia (Ganga-Bhagirathi-Hooghly system).
- NW 2: Sadiya to Dhubri (Brahmaputra river).
- NW 3: Kottapuram to Kollam (West Coast Canal).
- NW 4: Kakinada to Pondicherry (Godavari-Krishna-Canals).
Interlinking of Rivers (NRLP): Proposal to transfer water from surplus (Himalayan/Brahmaputra) to deficit basins (Peninsular). Ecological and geopolitical concerns.
India-WRIS: Refers to the Water Resources Information System.
Watershed Management: Integrated conservation of soil, water, and biomass within a hydrological unit to prevent degradation.

Climate and Mechanism of Indian Monsoon

📘 Syllabus Coverage

Syllabus	Topic Details
NEP-2020	Unit I — Climatic classification, Mechanism of Indian monsoon
UGC NET	Climate: Seasonal Characteristics, Climatic Divisions, Indian Monsoon

Get the Presentation ↗ | Watch the Video ↗

Key Concepts

Characteristics: Tropical Monsoon climate. Four seasons: Winter, Pre-Monsoon (Summer), Southwest Monsoon, Post-Monsoon (Retreating).
Monsoon Mechanism:
- Thermal Concept (Halley): Differential heating of land and sea.
- Dynamic Concept (Flohn): Shifting of the ITCZ northward over the Ganga plain.
- Jet Stream Theory (Yin): Sub-Tropical Westerly Jet moving north of Himalayas allowing Tropical Easterly Jet to establish, triggering the onset. Jet streams also influence glacier melting in the Himalayas (when the polar jet stream moves northward, it brings warm air to the region accelerating glacier melt).
- Oceanic Factors: El Niño (negative impact), Indian Ocean Dipole (Positive IOD enhances rainfall).
Climatic Classifications: Koeppen (Amw, Aw, BShw, Cwg), Trewartha.
Western Disturbances: Cyclonic storms from the Mediterranean bringing winter rain to NW India (crucial for Rabi crops).
**Local Storms:*
- NORWESTER: Also known as Kal Baisakhi, these are the most common summer storms in Bengal, Assam, and Odisha.
**Extreme Weather:*
- Cloudburst (IMD definition): Rainfall of \(\ge\) 10 cm in one hour.

Impact of Globalisation on Indian Economy

📘 Syllabus Coverage

Syllabus	Topic Details
UGC NET	Globalisation and its impact on Indian Economy

Get the Presentation ↗ | Watch the Video ↗

Key Concepts

Economic Transformation: Shift from import substitution to outward-looking, export-oriented economy post-1991.
Service Sector Boom: IT and BPO industries leveraging English-speaking workforce and time zone difference. Shifted GDP composition heavily towards tertiary sector.
