FAQs on Mind Map: Geomorphic Processes - Geography Class 11 - Humanities/Arts

1. What are the main types of geomorphic processes?
Ans. The main types of geomorphic processes are weathering, erosion, transportation, and deposition. Weathering involves the breaking down of rocks into smaller particles, while erosion refers to the removal of these particles by natural forces such as water, wind, or ice. Transportation is the movement of eroded materials, and deposition occurs when these materials settle in a new location, forming new landforms.
2. How do human activities influence geomorphic processes?
Ans. Human activities, such as deforestation, urbanization, and mining, can significantly alter geomorphic processes. Deforestation can increase soil erosion as tree roots that stabilize the soil are removed. Urbanization leads to increased runoff and can change the natural flow of water, while mining can remove large areas of land and disrupt natural processes, leading to increased erosion and sedimentation in nearby waterways.
3. What is the role of climate in shaping geomorphic processes?
Ans. Climate plays a crucial role in shaping geomorphic processes by influencing weathering rates, erosion, and sediment transport. For instance, areas with high rainfall may experience more intense weathering and erosion due to increased water flow, while arid regions may see slower weathering processes. Temperature variations can also affect freeze-thaw cycles, impacting rock breakdown and landscape formation.
4. Can you explain the difference between mechanical and chemical weathering?
Ans. Mechanical weathering involves the physical breakdown of rocks into smaller pieces without changing their chemical composition, often through processes like freeze-thaw or abrasion. In contrast, chemical weathering involves the alteration of the chemical structure of rocks, such as when minerals react with water or acids, leading to changes in the rock's properties and structure.
5. What are some common landforms created by geomorphic processes?
Ans. Common landforms created by geomorphic processes include mountains, valleys, plateaus, hills, and deltas. Mountains can form through tectonic forces and erosion, valleys are typically shaped by river erosion, plateaus result from volcanic activity or uplift, hills may form through deposition, and deltas are created where rivers deposit sediments at their mouths, leading to fertile land.
