V-shaped valleys in the continental shelf and slope are called submarine canyons. These are deep, steep-sided valleys that cut across the continental margin and are often formed by underwater processes such as turbidity currents or erosion by underwater currents. Submarine canyons can be comparable in scale to canyons found on land.
Erosion contributes to the formation of deep valleys and canyons by gradually wearing away the rock and soil over time through processes like water flow, wind, and ice movement. The continuous removal of these materials deepens and widens the valleys and canyons, creating the distinctive landforms we see today.
Both canyons and valleys are landforms that are shaped by erosion. They are both depressions in the earth's surface surrounded by higher terrain. Canyons are typically deeper and narrower than valleys.
Submarine canyons. These are steep-sided valleys that cut into the continental slope and sometimes extend onto the continental shelf. Submarine canyons can be formed by various processes, including erosion from turbidity currents or underwater landslides.
Canyons and sand dunes are landforms created by the action of wind and water erosion. Both features are formed over time through the erosion and transportation of sediment. Canyons are deep valleys carved by rivers, while sand dunes are large mounds of sand shaped by wind.
valleys and canyons are sometimes created by glaciers.
Valleys.
In many cases, rivers are responsible for cutting valleys and canyons.
That is the correct spelling of the plural noun "canyons" (mountain valleys).
Canyons and valleys are typically formed by the erosion of rock and sediment by water, wind, or ice over long periods of time. They can also be created by tectonic activity, such as the shifting of Earth's crust along fault lines. Additionally, volcanic activity can form canyons and valleys as lava flows and subsequent erosion shape the landscape.
Pluto has only been observed from orbit, so we don't know for sure, but it does appear from photos that there are valleys and canyons.
