Question

How did the effects of weathering contribute to the formation of landforms along the Nile River?

1) By eroding the surrounding rocks and depositing sediment along the riverbanks
2) By creating deep valleys and canyons through the erosion of the riverbed
3) By weathering the rocks and forming sedimentary deposits along the river
4) By causing the river to meander and create floodplains

Answer 1

The effects of weathering, including erosion and sediment deposition, contribute to the formation of landforms along the Nile River.

Step-by-step explanation:

The effects of weathering contribute to the formation of landforms along the Nile River in several ways:

1. Erosion: Weathering processes such as mechanical weathering and chemical weathering break down the rocks along the riverbanks. This erosion action helps to shape the landforms by removing the surrounding rocks and carrying the sediment along the river, depositing them along the riverbanks.
2. Floodplains: The weathering and erosion processes also contribute to the formation of floodplains. Over time, the river's meandering path and the continuous deposition of sediment along the riverbanks cause the river to flood and create flat, fertile floodplains.
3. Sedimentary deposits: Weathering of the rocks along the Nile River also leads to the formation of sedimentary deposits. The eroded materials and sediments get transported by the river and deposited in areas where the river slows down, such as river deltas and estuaries.
