They are high in energy and carry a large load of rock debris.
High levels of abrasion and lateral/ vertical erosion.…

Playas

Temporary lakes in shallow inland a basins

When rivers flow into these basins they form temporary lakes.

Canyons

Narrow river valleys with near vertical edges
There are two types slot canyon and step canyon.
Slot canyons are made up of high resistant rock, so only vertical erosion is
possible, this keeps the canyon narrow and steep edged.
Step canyons are made of alternate horizontal layers of high…
