Any living organism that modifies the Earth's surface Explanation: A geomorphic agent is any exogenic element of nature, like water, ice, or wind, that can acquire and transport Earth materials.3 / 203. What is exfoliation? A. The transportation of sediments by glaciers B. The breakdown of rocks by chemical reactions C. The flaking off of curved sheets from rocks D. The formation of rocks by biological activity Explanation: Exfoliation is the result of flaking off of more or less curved sheets of shells from over rocks or bedrock, resulting in smooth and rounded surfaces.4 / 204. What is the phenomenon of wearing down relief variations on the Earth’s surface called? A. Gradation B. Epeirogeny C. Orogeny D. Denudation Explanation: Gradation is the process of wearing down relief variations on the Earth’s surface through erosion.5 / 205. What is the ultimate source of energy for exogenic processes? A. The Earth's internal heat B. Gravitational forces C. Chemical reactions D. The sun Explanation: Exogenic processes derive their energy from the atmosphere, which is determined by the ultimate energy from the sun.6 / 206. What is the primary cause of the uneven surface of the Earth? A. Gravitational forces from the moon B. Sunlight C. External forces from the atmosphere D. Internal forces within the Earth Explanation: The variations in the Earth’s outer surface are primarily due to the differences in internal forces operating from within the Earth. 7 / 207. What is the primary role of gravity in geomorphic processes? A. It prevents erosion and deposition. B. It causes stresses on Earth materials and activates downslope movements. C. It causes volcanic eruptions. D. It influences the Earth's magnetic field. Explanation: Gravity not only activates all downslope movements of matter but also causes stresses on Earth materials.8 / 208. How do burrowing animals contribute to weathering? A. They break down rocks with their teeth. B. They expose new surfaces to chemical attack and assist in the penetration of moisture and air. C. They change the Earth's magnetic field. D. They transport sediments over long distances. Explanation: Burrowing animals help in exposing new surfaces to chemical attack and assist in the penetration of moisture and air, contributing to weathering.9 / 209. What is the main cause of the reduction in the Earth’s potential to sustain life? A. Climate change B. Natural disasters C. Volcanic eruptions D. Overuse of resources by humans Explanation: Humans have caused extensive damage to the environment through the overuse of resources, leading to a reduction in the Earth’s potential to sustain life.10 / 2010. What are geomorphic processes? A. The processes that cause earthquakes B. The processes that form rocks C. The processes that shape the Earth's surface D. The processes that drive atmospheric circulation Explanation: Geomorphic processes are the endogenic and exogenic forces that cause physical and chemical changes on Earth materials, leading to changes in the configuration of the Earth’s surface.11 / 2011. What are endogenic forces primarily responsible for? A. Wearing down landforms B. Building up landforms C. Transporting sediments D. Creating atmospheric circulation Explanation: Endogenic forces are primarily land-building forces, while exogenic forces are land-wearing forces.12 / 2012. Which of the following is an endogenic geomorphic process? A. Diastrophism B. Deposition C. Erosion D. Weathering Explanation: Diastrophism and volcanism are endogenic geomorphic processes.13 / 2013. What is biological weathering? A. The formation of rocks by chemical processes B. The transportation of sediments by rivers C. The breakdown of rocks by wind D. The contribution to or removal of minerals and ions from the weathering environment due to organisms Explanation: Biological weathering involves the contribution to or removal of minerals and ions from the weathering environment and physical changes due to the growth or movement of organisms. 14 / 2014. What is orogeny? A. A volcanic eruption process B. A soil formation process C. A continent-building process D. A mountain-building process Explanation: Orogeny is a mountain-building process, whereas epeirogeny is a continent-building process.15 / 2015. Why is it important to understand the nature of the Earth’s surface? A. To explore space B. To predict earthquakes C. To use it effectively without disturbing its balance D. To develop new technologies Explanation: Understanding the nature of the Earth’s surface is essential for using it effectively without disturbing its balance and diminishing its potential for the future.16 / 2016. What is stress in the context of geomorphic processes? A. The weight of overlying rocks B. Force applied per unit area C. Temperature changes in rocks D. The movement of water through rocks Explanation: Stress is the force applied per unit area, produced in a solid by pushing or pulling, which induces deformation.17 / 2017. What does volcanism include? A. The formation of glaciers B. The movement of magma onto or toward the Earth's surface C. The deposition of sediments by rivers D. The erosion of rocks by wind Explanation: Volcanism includes the movement of molten rock (magma) onto or toward the Earth’s surface and the formation of various intrusive and extrusive volcanic forms.18 / 2018. What are exogenic forces? A. Forces originating from within the Earth B. Gravitational forces C. Forces originating from within the Earth's atmosphere D. Magnetic forces Explanation: Exogenic forces are external forces that originate within the Earth’s atmosphere.19 / 2019. What is diastrophism? A. The process of rock formation B. All processes that move, elevate, or build up portions of the Earth's crust C. The process of volcanic eruption D. The process of soil formation Explanation: Diastrophism encompasses all processes that move, elevate, or build up portions of the Earth’s crust.20 / 2020. What is the main source of energy for endogenic geomorphic processes? A. Radioactivity, rotational and tidal friction, and primordial heat B. Hydroelectric energy C. Solar energy D. Wind energy Explanation: The energy emanating from within the Earth, mostly generated by radioactivity, rotational and tidal friction, and primordial heat, is the main force behind endogenic geomorphic processes.Please insert your information to see your ranking अपनी Ranking जानने के लिए कृपया अपनी जानकारी भरे NamePhone Number Your score isThe average score is 0% 0% Restart quiz Category: Class 11 Geography Quizzes in English
