The correct answer is option 'A': Ganga.
The Ganga River, also known as the Ganges, forms the largest delta in the world. Let's explore this in more detail.
Delta Formation:
A delta is a landform that forms at the mouth of a river where it meets a body of water, such as an ocean or a lake. It is created by the deposition of sediment carried by the river over time. As the river flows into the body of water, it slows down, and the sediment it carries settles down. This deposition of sediment forms a triangular-shaped landform with multiple distributaries branching out from the main river channel.
The Ganga Delta:
The Ganga River, originating from the Gangotri Glacier in the Himalayas, is one of the longest rivers in the world, with a length of approximately 2,525 kilometers (1,569 miles). It passes through the northern and eastern parts of India, flowing through several states before finally reaching the Bay of Bengal.
The Ganga Delta, also known as the Sundarbans Delta, is located in the Bay of Bengal and spreads across Bangladesh and the Indian state of West Bengal. It is formed by the sediment deposited by the Ganga and Brahmaputra rivers, which merge and flow into the Bay of Bengal. The delta covers an area of about 105,000 square kilometers (40,541 square miles).
Key Features of the Ganga Delta:
1. Size: The Ganga Delta is the largest delta in the world in terms of area.
2. Biodiversity: It is renowned for its rich biodiversity and is home to the Sundarbans, the largest mangrove forest in the world. The Sundarbans is a UNESCO World Heritage Site and is known for its unique flora and fauna, including the Royal Bengal Tiger.
3. Agriculture: The fertile soil of the delta supports extensive agriculture, making it an important agricultural region.
4. River Channels: The Ganga Delta is characterized by numerous distributaries and smaller river channels that crisscross the region, forming an intricate network.
In conclusion, the Ganga River forms the largest delta in the world, known as the Ganga or Sundarbans Delta. It is a significant geographical feature, known for its size, biodiversity, fertile soil, and intricate river channels.
