Ridge de sédiments
The French word for a ridge of sediment, gravel, silt, and other materials is "alluvion."
levee
Another word for mountain ridge is arête which is the French word for edge or ridge.
it is older
Sediment closer to a mid-ocean ridge is typically younger, thinner, and composed of more volcanic material compared to sediment farther away. This is because the ridge is a site of active seafloor spreading where new oceanic crust is formed, leading to a higher rate of sedimentation near the ridge.
It's thinner
The basaltic crust becomes newer the closer it is to the ridge and has therefore had less time of exposure to sedimentation. New crustal rock is formed at the mid-oceanic ridge. An inch or two a year.
Sediment closer to a mid-ocean ridge tends to be younger, coarser, and more abundant due to the higher rate of volcanic and tectonic activity in those areas. In contrast, sediment farther away from the ridge is older, finer, and less abundant as it has had more time to accumulate and undergo erosion.
No, the ridge is primarily composed of the windblown glacially derived sediment.
Sediment closer to mid-ocean ridges is typically younger, coarser, and consists of more volcanic material compared to sediment farther away. This is because the closer proximity to the ridge results in a higher input of freshly erupted material from the underlying volcanic activity.
