2) 📝 Chapter Summary (English ~250 words)
India has a long and scenic coastline of about 7,500 kmWestern Coastal Plains (between the Arabian Sea and the Western Ghats) and the Eastern Coastal Plains (between the Bay of Bengal and the Eastern Ghats). The western side is narrow and broken into three parts: the Gujarat Coast, the Konkan Coast (Maharashtra–Goa) and the Malabar Coast (Kerala). The east is wider—on average about 120 km—and includes the Coromandel Coast and Northern Circars. Many east-flowing rivers form fertile deltas.
Ports and harbours make the coasts important for trade and transport. Major ports include Mumbai on the Konkan Coast and Chennai, Visakhapatnam and Paradip on the east. Lighthouses along the Konkan Coast guide ships at night. The western coast gets heavy rain during the south-west monsoon, while the eastern coast experiences cyclones and rain from the north-east monsoon too.
India also has two island groups. The Andaman and Nicobar Islands (over 500 islands) lie in the Bay of Bengal; the southernmost point of India, Indira Point, is in the Nicobars. Their capital is Port Blair. The Lakshadweep Islands in the Arabian Sea are coral islands with about 30–36 small islands; the capital is Kavaratti. The main occupations on the islands are fishing, agriculture and tourism.
Thus, the coastal plains and islands support India’s economy through ports, shipbuilding, fishing and tourism, while their beaches, backwaters and marine life add to our country’s natural beauty.
3) 📝 अध्याय का सार (हिंदी ~250 शब्द)
भारत की तटरेखा लगभग 7,500 किमी लंबी है। इसे दो भागों में बाँटा जाता है—पश्चिमी तटीय मैदान (अरब सागर और पश्चिमी घाटों के बीच) और पूर्वी तटीय मैदान (बंगाल की खाड़ी और पूर्वी घाटों के बीच)। पश्चिमी तट सँकरा है—गुजरात तट, कोकण तट और मालाबार तट में बँटा है। पूर्वी तट अपेक्षाकृत चौड़ा है—औसत 120 किमी—और इसमें कोरोमंडल तट व नॉर्दर्न सर्कार शामिल हैं। यहाँ नदियाँ विशाल डेल्टा बनाती हैं।
तटीय क्षेत्रों में बंदरगाह व हार्बर होने से व्यापार और यातायात को बढ़ावा मिलता है। कोकण तट पर मुंबई और पूर्वी तट पर चेन्नई, विशाखापत्तनम, परेडीप प्रमुख बंदरगाह हैं। जहाज़ों को दिशा देने के लिए कोकण तट पर कई लाइटहाउस बने हैं। पश्चिमी तट पर दक्षिण-पश्चिम मानसून से भारी वर्षा होती है, जबकि पूर्वी तट पर उत्तर-पूर्वी मानसून और चक्रवातों का प्रभाव भी पड़ता है।
भारत के दो प्रमुख द्वीप-समूह हैं—अंडमान-निकोबार (बंगाल की खाड़ी) जिनमें 500 से अधिक द्वीप हैं और दक्षिणतम बिंदु इंदिरा प्वाइंट भी यहीं है; इनकी राजधानी पोर्ट ब्लेयर है। लक्षद्वीप (अरब सागर) प्रवाल द्वीपों का समूह है; राजधानी कवरत्ती है। द्वीपों पर मुख्य आजीविका मछली पालन, कृषि और पर्यटन है।
इस प्रकार तटीय मैदान और द्वीप भारत की अर्थव्यवस्था में महत्वपूर्ण भूमिका निभाते हैं तथा प्राकृतिक सौंदर्य और जैव-विविधता को समृद्ध करते हैं।
