A canyon is a large, deep valley that is carved into rock over a long period of time. Which of the following most likely causes a canyon to form?

Answer:Sometimes, tectonic activity causes an area of the Earth's crust to rise higher than the surrounding land. This process is called tectonic uplift. Tectonic uplift can create plateaus and mountains. Rivers and glaciers that cut through these elevated areas of land create deep canyons.
