Assertion and Reasoning Type Question
Assertion: Terrace cultivation does not restrict erosion.
Reason: Running water cuts through the clayey soils and makes deep channels as gullies. This helps to cultivate crops.
Explanation:
• Terrace cultivation is a method of farming in which a series of flat platforms are built on the slopes of hills and mountains to grow crops.
• The assertion states that terrace cultivation does not restrict erosion.
• The reason given for this assertion is that running water cuts through the clayey soils and makes deep channels as gullies. This helps to cultivate crops.
• However, this reason is not the correct explanation of the assertion. In fact, it contradicts the assertion.
• Terrace cultivation is actually a method of soil conservation as it helps to prevent soil erosion by slowing down the flow of water and reducing the velocity at which it runs down the slope.
• The flat platforms created in terrace cultivation help to reduce the speed of water flow, and the retaining walls help to hold the soil in place, preventing soil erosion.
• Terrace cultivation also allows for better water management, as the water is retained on the terraces and can percolate into the soil, rather than running off the slope and causing erosion.
• Therefore, the correct answer is option 'B'. Both assertion and reason are true but reason is not the correct explanation of assertion.
