Question

Which of the following best describes the transportation phase of gradation of a river?

• A. The flow of a river from its source: glacier, mountains, and lakes
• B. The sediments in the river that erode the rocks
• C. The mixing of eroded material in water as the river flows to flatter regions
• D. The deposition of the sediments on the banks of the river

Answer 1

The correct option is C The mixing of eroded material in water as the river flows to flatter regions

The running water creates a variety of landforms through erosion, transportation, and deposition. Denudation starts when the river leaves its source. Along its course, the water and its sediments constantly erode the rocks and other obstacles that come in its path. The eroded material gets mixed in the water and transported with the flow. Finally, the eroded material gets deposited, and landforms are created.
