8, 9, 10 Degree Channels: All you need to know
A channel is a broad open waterway that passes through two landmasses that lie close to each other. It is different from the strait which is a relatively narrow body of water, connecting two larger bodies of water.
As per National Geographic, it is the deepest part of a waterway/narrow water body that connects two larger bodies of water.
Channels are created either by glaciers or by people. The channels that are created by glaciers carve out deep canyons between two landmasses. The channels that are created by people are usually dug from the bottoms of shallow waterways to build a passage for large ships.
