Deltas are formed at river mouths where the river slows and deposits silt and sediment, creating a fan- or triangle-shaped landform. These deposits are rich in minerals, making the soil highly fertile. Rivers like Ganga, Godavari, Krishna and Mahanadi form vast deltas on India’s east coast. These deltas support intensive agriculture due to their nutrient-rich soil and ample water supply. They are also home to many species of birds and fish, making them ecologically and economically significant.

Coral reefs are vibrant underwater ecosystems built by coral polyps, which secrete calcium carbonate to form reef structures. These reefs support countless marine species and are crucial for biodiversity. In India, prominent coral reef areas include the Lakshadweep Islands andaman and Nicobar Islands and the Gulf of Mannar near Tamil Nadu. Reefs provide coastal protection, fishing resources and tourism opportunities. However, they are fragile and face threats from climate change, pollution and overfishing, requiring conservation efforts.
