Consider the following pairs:1. Youth Stage of Landform - Initial Sta...

1. Youth Stage of Landform - Initial Stage of Development
This is correctly matched. In the youth stage, the landform is in its initial stage of development.

2. Mature Stage of Landform - Peak of Erosional Activities
This is correctly matched. In the mature stage, erosional activities are at their peak, and the landscape is more defined with valleys and hills.

3. Old Stage of Landform - Formation of New Landforms
This is incorrectly matched. The old stage is characterized by reduced erosion and more deposition leading to flatter terrains, not the formation of new landforms.

4. Running Water - Primary Agent in Arid Regions
This is incorrectly matched. Running water is a primary agent in regions with high humidity and heavy rainfall, not in arid regions where wind is more dominant.

Thus, only the first and second pairs are correctly matched, making the answer Option A: Only one pair.

Similar Humanities/Arts Doubts

Consider the following statements:1. Landforms undergo three stages called youth, mature, and old stages.2. Running water is the primary geomorphic agent in regions with high humidity and heavy rainfall.3. Erosional landforms created by running water are predominantly associated with mature rivers flowing over gentle gradients.Which of the statements given above is/are correct?

View answer

Direction: Read the case study given below and answer any three of the questions that follow.In humid regions, which receive heavy rainfall running water is considered the most important of the geomorphic agents in bringing about the degradation of the land surface. There are two components of running water. One is overland flow on general land surface as a sheet. Another is linear flow as streams and rivers in valleys. Most of the erosional landforms made by running water are associated with vigorous and youthful rivers flowing over steep gradients. With time, stream channels over steep gradients turn gentler due to continued erosion, and as a consequence, lose their velocity, facilitating active deposition. There may be depositional forms associated with streams flowing over steep slopes. But these phenomena will be on a small scale compared to those associated with rivers flowing over medium to gentle slopes. The gentler the river channels in gradient or slope, the greater is the deposition. When the stream beds turn gentler due to continued erosion, downward cutting becomes less dominant and lateral erosion of banks increases and as a consequence the hills and valleys are reduced to plains.Q. Name the two components of running water.
