Pluto, visible only through a telescope, appears to have valleys or fresh impact craters, that show up as darker spots. On Pluto, the Sun appears as only a bright star in the sky. Pluto is smaller than the Earth's Moon and consists of rock and ice.
there are some in canyons and some in valleys
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.
