FAQs on Audio Notes: बहते पानी से बनी भू-आकृतियाँ Video Lecture - यूपीएससी सीएसई के लिए भूगोल (Geography) - UPSC
| 1. What are the main types of landforms created by running water? |  |
Ans. The main types of landforms created by running water include valleys, riverbanks, floodplains, waterfalls, and deltas. Valleys are typically V-shaped and formed by the erosive power of rivers. Riverbanks are shaped by the flow of water, leading to erosion on one side and deposition on the opposite side. Floodplains are flat areas adjacent to rivers that are formed by sediment deposition during floods. Waterfalls occur where rivers flow over steep cliffs, creating a dramatic drop. Deltas form at river mouths where sediment is deposited as the river enters a larger body of water.
| 2. How does erosion and deposition by running water contribute to landscape formation? | |
Ans. Erosion and deposition by running water play a crucial role in shaping landscapes. Erosion occurs when flowing water removes soil and rock from one location, transporting it downstream. This process can create features like cliffs and canyons. Deposition happens when the water slows down, allowing the transported materials to settle. This can lead to the formation of landforms such as floodplains and deltas. Together, these processes continually reshape the earth's surface, influencing ecosystems and human activities.
| 3. What is the significance of floodplains in the context of running water landforms? | |
Ans. Floodplains are significant because they serve as fertile areas for agriculture due to the nutrient-rich sediments deposited by flooding rivers. They also provide critical habitats for wildlife and act as natural buffers that help mitigate flooding by absorbing excess water. Additionally, floodplains are important for human settlements as they often support transportation and infrastructure development due to their flat terrain and access to water resources.
| 4. Can you explain the process of delta formation by rivers? | |
Ans. Delta formation occurs when a river enters a standing body of water, such as a lake or ocean, and its velocity decreases. As the river slows down, it loses the energy required to carry sediment, causing the sediment to settle and accumulate. This process creates a fan-shaped landform known as a delta. Over time, the delta can grow and develop various sub-environments, such as marshes and wetlands, which are vital for biodiversity and water filtration.
| 5. How have human activities impacted landforms created by running water? | |
Ans. Human activities, such as dam construction, urbanization, and agriculture, have significantly impacted landforms created by running water. Dams can alter river flow, affecting sediment transport and deposition, which can lead to erosion downstream and changes in natural habitats. Urbanization often results in increased runoff, which can exacerbate erosion and lead to flooding. Agricultural practices can modify floodplains and riverbanks, impacting their natural processes and ecosystems. These alterations can disrupt the balance of the landscape and influence both natural and human systems.
