The Grand Canyon reaches a maximum depth of approximately 6,093 feet (1,857 meters) at its deepest point, known as the Grand Canyon Supergroup. The canyon's depth varies along its length, with the average depth being around 4,000 feet (1,200 meters). This impressive depth has been shaped over millions of years by the erosive power of the Colorado River and geological processes.
The biggest canyon on Mars, Valles Marineris, is much larger than the Grand Canyon on Earth. Valles Marineris stretches over 2,500 miles in length, up to 7 miles in depth, and reaches widths of up to 120 miles. In contrast, the Grand Canyon is approximately 277 miles long, 18 miles wide, and has a depth of about 1 mile.
Valles Marineris of Mars, has a depth of up to 7 km and a length of 4,000 km. This is equivalent to the length of Europe.The Grand Canyon by comparison, has a depth of 1.6 km and a length of 433 km.
Defining the largest canyon has been a debate due to the fact as to how do you measure the canyon, by length, total area, height. Grand Canyon in Arizona, USA depth 1,800 metres - 6,000 feet length 446 km - 277 miles width 6.4 to 29 km - 4 to 18 miles area 1,218,376 acres Hell's Canyon in Oregon-Idaho depth 2,436 metres - 7,993 feet length width 16 km - 10 miles area 600,000 acres Yarlung Zango Grand Canyon in China - the Longest Canyon depth 6,009 metres length 496.3 metres - 150 miles Cotahusai Canyon in Peru depth 3,535 metres - 11,597 feet Colco Canyon in Himalayas depth 3,140 metres Barranca del Cobre or Copper Canyon in Mexico depth 2,400 metres Fish Rivery Canyon in Namibia depth 550 metres length 160 km - 100 miles width 27 km
The Grand Canyon is not even close to the size of Valles Marinaris. Grand Canyon length 446 km Valles Marinaris length 4000 km Grand Canyon maximum width 29 km Valles Marinaris maximum width 200 km Grand Canyon maximum depth 1.83 km Valles Marinaris maximum depth 7 km
It is the only place on earth that has been carved out by water erosion to such a great depth and area.
At its deepest point it is over a mile.
Colca canyon in Peru is 10500 feet in depth
The floor of the Canyon reaches a depth of about 6,000 feet.
The Colca Canyon is more than twice as deep as the Grand Canyon. This canyon is located in the Andes Mountains of southern Peru. Its depth is over 13,000 feet.
