Origin of Indian Islands

(i) Bay of Bengal

-> Andaman and Nicobar islands are found off the coast of Eastern India.

-> These islands are volcanic in origin, formed due to tectonic movement of plates.

-> As the Indian plate collided

with Eurasian plate, syntaxial bend developed near Namcha Barwa, led to N-S orientation of Purvanchals.

-> Andaman & Nicobar are considered to be the extension of himalayan orogenisis, geologically matching the Arakan mountains of Myanmar.

-> Barren Island -> only live volcano of India, part of under sea volcanic mountain chain, the upraised part of which forms the Andaman & Nicobar islands.

(ii) Arabian sea Islands

-> Lakshadweep islands, located

480 km off the Malabar coast, comprises of 43 islands, only 11 are inhabited.

2These are coral islands, composed of dead coral deposits, rich in calcium carbonate, known as atolls.
3Atolls surround a shallow lagoon, formed due to subsidence of hills, composed of granitic crust.
4Gradually, the attached fringing & barrier reef are raised above sea level, and they cover the hollow to form coral islands.

5. Analyse the following poem critically and answer all the questions that follow : 10x5=50 The sea is calm tonight. The tide is full, the moon lies fair Upon the straits—on the French coast the light Gleams and is gone; the cliffs of England stand, Glimmering and vast, out in the tranquil bay. Come to the window, sweet is the night air ! Only, from the long line of spray Where the sea meets the moon-blanched land, Listen ! you hear the grating roar Of pebbles which the waves draw back, and fling, At their return, up the high strand, Begin, and cease, and then again begin, With tremulous cadence slow, and bring The eternal note of sadness in. Sophocles long ago Heard it on the Aegean, and it brought Into his mind the turbid ebb and flow Of human misery; we Find also in the sound a thought, Hearing it by this distant northern sea. The Sea of Faith Was once, too, at the full, and round earth's shore Lay like the folds of a bright girdle furled. But now I only hear Its melancholy, long, withdrawing roar, Retreating, to the breath Of the night wind, down the vast edges drear And naked shingles of the world. Ah, love, let us be true To one another ! for the world, which seems To lie before us like a land of dreams, So various, so beautiful, so new, Hath really neither joy, nor love, nor light, Nor certitude, nor peace, nor help for pain; And we are here as on a darkling plain Swept with confused alarms of struggle and flight, Where ignorant armies clash by night. (a) Explain the symbolism of the sea. (b) What is the poet mourning? (c) What does the poet invest his hopes in? (d) Explain the phrase "ignorant armies clash by night". (e) How does the poet build the mood of the poem? Comment on the imagery of the poem.
