Detailed explanation-1: -Delta: a nearly flat plain of alluvial deposit between diverging branches of the mouth of a river, often, though not necessarily, triangular. Tributary: a river or stream flowing into a larger river or lake.

Detailed explanation-2: -Deltas are wetlands that form as rivers empty their water and sediment into another body of water, such as an ocean, lake, or another river. Although very uncommon, deltas can also empty into land. A river moves more slowly as it nears its mouth, or end.

Detailed explanation-3: -Named for the fourth letter of the Greek alphabet (shaped like a triangle), a delta is a triangular area where a major river divides into several smaller parts that usually flow into a larger body of water. The first so-called delta was the Nile Delta, named by the Greek historian Herodotus.

Detailed explanation-4: -Deltas are areas near the mouth of a river or estuary, where these moving bodies of water deposit large amounts of sediment.

Detailed explanation-5: -Arcuate Delta: A bowed or curved delta with the convex margin facing the body of water. Estuarine Delta : it is formed at the mouth of submerged rivers depositing down the sides of the estuary. Birds foot Delta: They are formed due to deposition of finer materials by river water.
