A sandbar is a temporary, underwater or exposed ridge of sand, gravel, or shell material that is built up by currents in a river or by waves on a beach. It typically forms near the coast and can disappear or change shape depending on tides and currents.
An example of a sand bar is the narrow, underwater ridge of sand that forms parallel to a shoreline, such as the Outer Banks in North Carolina. These shallow underwater formations can become exposed at low tide and are important for protecting beaches from erosion.
Underwater eruptions cause tsunamis and cause lava to form and underwater ridge.
An underwater ridge near the surface of the water is called a seamount. These are elevated features on the seafloor that do not reach the surface of the water.
A mid-ocean ridge is not an underwater volcano. It is a long mountain range on the ocean floor formed by plate tectonics. Underwater volcanoes, also known as seamounts, are mountains that form from volcanic activity on the ocean floor.

The French word for a ridge of sediment, gravel, silt, and other materials is "alluvion."
A long winding ridge made from deposits of sand and gravel is called an esker. Eskers are formed by the melting of glaciers and the deposition of sediment as the flowing water carries and deposits material in a sinuous ridge-like form.
"un sillon" is probably what you are looking for. It is the term used for Japanese gardens of sand or gravel, or in agriculture for tilled fields.
The mid Atlantic ridge is an underwater mountain chain.
