The Grand Canyon is undoubtedly a fluvial landform. Over millions of years, the Colorado River has created the Grand Canyon out of the Colorado Plateau. Landforms produced by rivers and streams are referred to as fluvial landforms. It contains features made by these water bodies through both erosion and deposition.

Grand Canyon - A Fluvial Landform

  • Rock formations are more accessible to date than landscapes.
  • Still, geologists may approximate the ages of landscapes by examining the interactions between rock formations.
  • Researchers have used this relative dating method to determine the Colorado River's and Grand Canyon's ages.
  • The Colorado River carved the Grand Canyon, according to scientists.
  • Therefore, although the canyon and river are undoubtedly old, the river is a little older.
  • Researchers have looked at the current course of rock formations along the Colorado River.
  • Scientists can tell whether a river deposits rocks by looking at the kind of sediments the deposits contain.
  • Since the river had to be there to deposit the rocks, they are more recent than the river itself.
  • Because the river was not yet present to deposit them, rocks that the river did not deposit are older than the river.
  • The scientists then date these rock deposits when it is feasible.
  • The rocks that were younger than the river and those found to be older represent the river's age, respectively.
  • Using this technique, researchers have calculated that the river's age and the canyon it flows through is 5-6 million years.

Summary:

Is the Grand Canyon a fluvial landform?

Undoubtedly, the Grand Canyon is a fluvial landform. Over millions of years, the Colorado River carved the Grand Canyon out of the Colorado Plateau.
