Map of India — Physical and Political Geography
Introduction
'MAP MARKING is a MANDATORY part of ICSE Geography Paper 2. Every student MUST be able to locate and label PHYSICAL features (mountains, rivers, plateaus, plains) and POLITICAL features (cities, ports, airports) on an OUTLINE map of India. ICSE examiners say: "PRACTISE map marking. REVISE the list of important features. Know your EAST-WEST and NORTH-SOUTH extremes."'
Location and Extent

| Latitudinal Extent | 8°4'N to 37°6'N |
| Longitudinal Extent | 68°7'E to 97°25'E |
| Total Area | 3.28 MILLION sq km (7th largest in the world) |
| North-South Length | 3,214 km |
| East-West Width | 2,933 km |
| Indian Standard Time | 82°30'E (passes through MIRZAPUR, UP) |

Peninsular Plateaus
| Plateau | Location | Significance |

Map Marking Techniques
| Feature | How to Mark |
|---|---|
| Mountains | Range — label ALONG the range with arrow/line |
| Rivers | Label NEAR the river — use BLUE pen |
| Cities | DOT + NAME — use BLACK pen |
| Ports | ANCHOR symbol + name |
| Direction | Always mark NORTH direction |
Typical ICSE Map Questions
- 'Mark and label: (a) ARAVALLI RANGE, (b) RIVER GODAVARI, (c) MUMBAI PORT, (d) WESTERN GHATS'
- 'Mark the following on the outline map: (a) CHENNAI, (b) RIVER CAUVERY, (c) LACADIVE SEA'
Common Mistakes in ICSE Map Marking
| Mistake | Correction |
|---|---|
| Marking in the WRONG location | PRACTISE with a blank map |
| Using IMPROPER symbols | Follow ICSE conventional SYMBOLS |
| Forgetting to LABEL | Every marked feature MUST be labelled |
| Confusing EAST and WEST coast rivers | Narmada, Tapi = WEST flow. Others = EAST |
| Missing K2 / Karakoram | K2 is in the KARAKORAM range, NOT Himalayas |
ICSE Exam Focus — Marks Blueprint
| Question Type | Marks | Frequency |
|---|---|---|
| Mark physical features — mountains, rivers, plateaus | 4-6 | Always |
| Mark cities/ports | 3-4 | Always |
| Identify from marked features | 4-5 | Very High |
| Identify RIVERS from map | 4 | Very High |
