SUBMARINE CANYON

Submarine Canyons

• Submarine canyons are a type of narrow valley with steep sides that cut into the sides and hills of tectonic plates. On the continental shelf or the hills of a landmass, submarine canyons form.
• They don't happen very often on the edges of continental plates where there are steep hills or cliffs.
• The name of the area comes from the names of the valleys that rivers have made on land.
• Deep-sea pits are formed when one tectonic plate slides under another.
• Undersea canyons, on the other hand, are found along the edges of most continental plates.
• Rivers that cut across continental shelves, slopes, and hills create them by washing sands down. After that, the sands are dumped on the abyssal lands.

Submarine Canyon Characteristics

• It's more likely for submarine canyons to form on the steep sides of active margins than on the softer sides of inactive margins.
• They show wear on all types of surfaces, from sand that hasn't formed a shell to crystalline rock.
• When it comes to gorges, those on active continental margins are steeper, shorter, denser, and closer together than those on inactive continental margins.
• The walls are often very steep and can get very close to being vertical. Bioerosion and sinking are possible with these walls.
• There are about 9,477 underwater canyons in the world, which make up about 11% of the mainland slope.

Submarine Canyon Types

• Weathering, sediment, and living things all worked together to create these features in the ocean.
• Most of the time, they are found at higher levels because they result from diastrophic traits.
• In general, there are three kinds of underwater canyons:

1. Bank

• A bank is a flat-topped hill that is usually found on the edges of continents.
• The main things that lead to banks being formed are erosion and depositing money.
• The bank has a small layer of water on top of it, but the depth is good enough for passage. These places are good for fishing.
• Such as the Grand Banks in the North Atlantic and the Dogger Bank in the North Sea.

2. The Shoal

• A shoal is a buildup of sand or gravel in a river waterway or on the continental coast that can be dangerous for ships.
• Most of the time, less than 10 m (33 feet) below water level at low tide is thought to be the continental shelf.

3. Reef

• Coral reefs are ridges or bumps in the ocean that are made up of algae and limestone shells, usually coral polyps.
• It is possible for a coral reef to turn into a fixed coral island.
• A lot of different kinds of animals live in coral reefs, which are sometimes called "rainforests of the sea."
• The Pacific Ocean is known for its coral reefs, which are found near seamounts and guyots.
