8, 9 and 10 Degree Channel

A channel is a wide river or waterway that connects two islands that are close to each other.  A channel is a narrow body of water that connects two bigger bodies of water. It can also be the deepest point of a river. Glaciers cut down deep valleys between two landmasses, forming some of the channels. People generally dig channels from the bottoms of small waterways so that huge ships can pass through. These are referred to as navigation channels. The English Channel is a waterway that separates England and France. 

At its narrowest point, the Strait of Dover, the English Channel is 560 kilometres (348 miles) long and 34 kilometres (21 miles) broad. The English Channel has long been a natural barrier that separates England from the rest of Europe. The Ambrose Channel, which runs into New York Harbor, has been artificially deepened to allow huge cargo ships from the Atlantic Ocean to enter the sea.

Formation of Geographical Channel

The site on a mountain slope where the water begins to flow between identifiable banks is known as channel initiation. This site is known as the channel head, and it marks an important boundary between hillslope and fluvial processes. The channel head, which is defined by flowing water between clearly recognisable banks, is the most upslope component of a channel network. When overland and/or subsurface flow reaches a point where shear force may overcome the ground surface's erosion resistance, a channel head occurs. Colluvium, hollows, and landslides are usually connected with channel heads.

When saturated overland flow deepens to raise shear stress and commence channel incision, it is a key element in channel initiation. In topographic depressions, where channel initiation begins, overland flows converge. The volume and rate of overland flow are determined by soil type, vegetation, precipitation, and topography. The composition of soil controls how quickly it becomes saturated, and cohesive strength prevents material from being entrained by overland flows. Plant roots anchor soil on hillslopes and decrease infiltration rates during precipitation events.

Types of Geographical Channel

In the Bay of Bengal, 8, 9, and 10-degree channel separates differently, the Eight Degree Channel separates Minicoy and the Maldives, the Nine Degree Channel separates Minicoy from the main Lakshadweep archipelago, and the 10 Degree Channel separates the Andaman Islands and the Nicobar Islands. A channel is a large open waterway that connects two landmasses that are closely related. 

A strait, on the other hand, is a narrow waterway that links two larger bodies of water. It is the deepest part of a waterway/narrow water body that connects two larger bodies of water, according to National Geographic. Glaciers and people both cause the formation of channels. Glaciers carve out deep canyons between two landmasses by creating channels. Human-made channels are typically dug from the bottoms of shallow waterways to create a passage for large ships.

1. 8 Degree Channel

Eight Degree Channel is the name given to it on British Admiralty charts. It is named after the fact that it is located north of the equator on the 8-degree line of latitude. Addigiri Kandu is another local name for this waterway. Traditional names for the broad Minicoy Channel between Minicoy and the Maldives' northernmost atoll are Maliku Kandu and Mmal Kandu Divehi. The latter name celebrates Maamaley Marakkaaru, a Malabar merchant who controlled the sea trade along this route before the entrance of the Portuguese in the Indian Ocean. The Maldives and India have a sea boundary that goes via the channel.

2. 9 Degree Channel

The Nine Degree Channel connects the Laccadive Islands of Kalpeni and Suheli Par, and Maliku Atoll, in India. The Indian Union Territory (UT) of Lakshadweep is made up of these two subgroups of islands, as well as the Amindivi Subgroup. The Channel is around 200 kilometres wide and 2597 metres deep. The Investigator Bank is located in the channel's southern portion. It is named after the fact that it is located north of the equator on the 9-degree line of latitude.

3. 10 Degree Channel

The Ten Degree Channel is a channel in the Bay of Bengal that connects the Andaman and Nicobar Islands. The Indian Union Territory (UT) of the Andaman and Nicobar Islands is made up of two groups of islands. From north to south, this channel is 150 kilometres (93 miles) wide and approximately 10 kilometres (6.2 miles) long. It has a minimum depth of 7.3 metres and is located on the 10-degree latitude line north of the equator, hence the name.
