Question

where do river originate​

Answer 1

Answer:

What is a river? Rivers originate in the mountains, very often in glaciers, vast reserves of permanent ice which derive from the snow deposited at high altitudes or in the polar regions. While snowflakes fall to earth a small quantity of air in miniscule particles remains frozen and trapped inside the snow crystals.

Answer 2

• A river is a course of water that originates in the mountains and flows downwards until it reaches the sea.
