Answer

Fluvial landforms are features created by the action of running water, such as rivers. These include valleys, waterfalls, meanders, oxbow lakes, and deltas. They result from the combined processes of …

Answer

River erosion occurs in four ways: (1) Hydraulic action – force of water breaks rocks; (2) Corrosion/Abrasion – rock particles scrape river bed; (3) Solution – water dissolves soluble rocks like limes…

Answer

A 'V'-shaped valley is formed in the upper course of a river where vertical erosion dominates. The river cuts downward rapidly, while weathering weakens the valley sides, causing landslides that widen…

Answer

A gorge is a deep, narrow valley with steep sides, often formed in hard rock. A canyon is a very deep gorge with vertical walls, usually longer and wider, like the Grand Canyon. Both are formed by int…

Answer

Meanders are large, winding bends in a river, formed in the middle and lower courses due to lateral erosion. As the river erodes the outer bank and deposits on the inner bank, it creates snake-like cu…

Answer

An oxbow lake forms when a meander loop becomes so pronounced that the river cuts through the narrow neck during flooding. The loop is cut off, leaving a crescent-shaped lake isolated from the main ch…

Answer

A delta is a triangular-shaped depositional feature formed at the river’s mouth when it deposits sediments into a sea or lake. It has distributaries instead of a single channel. Example: The Ganga-Bra…
