Assertion (A)- Valleys start as small and narrow rills; the rills will gradually develop into long and wide gullies; the gullies will further deepen, widen, and lengthen to give rise to valleys.
Reason (R)- In streams that flow rapidly over steep gradients, normally erosion is concentrated on the bottom of the stream channel
Consider the following pairs:
1. Youth Stage of Landform - Initial Stage of Development
2. Mature Stage of Landform - Peak of Erosional Activities
3. Old Stage of Landform - Formation of New Landforms
4. Running Water - Primary Agent in Arid Regions
Which pair/pairs is/are given above are correctly matched?
Statement i: Peneplain: A nearly level plain formed by prolonged erosion.
Statement ii: Gorge: A deep valley with steep sides, often formed by a river.
Statement iii: Plunge Pool: A deep hole at the base of a waterfall formed by the impact of water.
Statement iv: Canyon: A narrow valley with steep, step-like sides, wider at the top than at the bottom.
Which of the statements is/are true?
Which of the following is the primary geomorphic agent responsible for land surface degradation in regions with high humidity and heavy rainfall?
What is the primary characteristic of alluvial fans formed by streams flowing from higher elevations?
Which coastal feature is formed as a ridge of sand and shingle lying approximately parallel to the coast and typically exposed during low tide?
What is the primary geomorphic agent responsible for land surface degradation in areas with high humidity and heavy rainfall?
Assertion (A): River terraces are surfaces marking old valley floor or floodplain levels and are products of erosion due to vertical erosion by the stream into its own depositional floodplain.
Reason (R): Alluvial fans are formed when streams flowing from higher levels break into foot slope plains of low gradient and deposit coarse load as broad low to high cone-shaped deposits.
Consider the following statements:
1. Stalactites are icicle-shaped formations that hang from the ceilings of limestone caves.
2. Stalagmites are structures that rise up from the floor of caves, often directly below stalactites.
3. Glaciers move primarily due to the melting of ice at their bases.
Which of the statements given above is/are correct?
Consider the following statements:
1. During the youth stage of landscape development in running water regimes, streams have poor integration and flow over original slopes.
2. In the mature stage, stream divides are broad and flat with marshes, swamps, and lakes.
3. The old stage of landscape development is characterized by streams meandering freely over vast floodplains with features like natural levees and oxbow lakes.
Which of the statements given above is/are correct?
Which of the following stages do landforms undergo as they evolve over time?
