Why is delta formation more common in east flowing Peninsular rivers?

Correct answer: They deposit sediments on the eastern coast

Direct answer: Option A is correct. A delta forms when a river carries sediment to its mouth and loses enough speed or energy for that sediment to settle. Many east-flowing Peninsular rivers cross broad, gently sloping plains and enter the shallow Bay of Bengal. These conditions favour deposition, so rivers such as the Mahanadi, Godavari, Krishna, and Kaveri commonly form deltas. Option A correctly identifies sediment deposition at the eastern coast. Option B is wrong because these rivers do reach the sea. Option C is wrong because it describes a feature on the western coast, not the main reason for eastern delta formation. Option D is wrong because Peninsular rivers are not all glacier-fed. The statement is a broad geographical pattern, not an exceptionless rule: mouth form also depends on sediment supply, waves, tides, and coastal shape. For school comparison, remember east-flowing rivers generally form deltas, while several west-flowing rivers form estuaries. Memory cue: east coast—broad deltaic deposition; west coast—narrow coast and more estuaries.
