Question

Tributary and distributary

Answer 1

Tributaries and distributaries are streams of fresh water bodies varying in their direction of flow. Tributaries are small streams of water that join the mainstream river to increase its water supply. They originate from glaciers, lakes and underground water streams. They join the river during its course mostly in its middle and younger stage. Distributaries, on the other hand, occur as a result of branching of a river near its mouth at a low-lying delta region. River carries a huge amount of silt and gravel at it mouth and this enhanced volume results into the branching of the river from it main channel. These streams are known as distributaries.
