What type of weathering causes canyons?
Mechanical weathering wears away at rock through physical forces, causing it to crumble and break apart. The Grand Canyon was created by mechanical weathering (and its pal erosion), as water from the Colorado River pushed past the rocky surface of the canyon for millions of years, making a deeper and deeper V-shape.
How is Canyon formed?
Most canyons were formed by a process of long-time erosion from a plateau or table-land level. The cliffs form because harder rock strata that are resistant to erosion and weathering remain exposed on the valley walls.
Why do Canyons form quickly?
Rapid megafloods may have formed canyons in the distant past as glacial ice dams released trapped water. Large floods may be responsible for the formation of some Martian canyons as well, the study suggests.
