What is the ultimate source of energy for exogenic processes? A. The Earth's internal heat B. The sun C. Chemical reactions D. Gravitational forces Explanation: Exogenic processes derive their energy from the atmosphere, which is determined by the ultimate energy from the sun.3 / 203. What is biological weathering? A. The formation of rocks by chemical processes B. The contribution to or removal of minerals and ions from the weathering environment due to organisms C. The breakdown of rocks by wind D. The transportation of sediments by rivers 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. 4 / 204. What is the main cause of the reduction in the Earth’s potential to sustain life? A. Overuse of resources by humans B. Natural disasters C. Climate change D. Volcanic eruptions 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.5 / 205. Why is it important to understand the nature of the Earth’s surface? A. To use it effectively without disturbing its balance B. To explore space C. To predict earthquakes 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.6 / 206. What is stress in the context of geomorphic processes? A. The movement of water through rocks B. Force applied per unit area C. Temperature changes in rocks D. The weight of overlying rocks Explanation: Stress is the force applied per unit area, produced in a solid by pushing or pulling, which induces deformation.7 / 207. What is the primary cause of the uneven surface of the Earth? A. Sunlight B. Internal forces within the Earth C. External forces from the atmosphere D. Gravitational forces from the moon Explanation: The variations in the Earth’s outer surface are primarily due to the differences in internal forces operating from within the Earth. 8 / 208. What is the phenomenon of wearing down relief variations on the Earth’s surface called? A. Gradation B. Denudation C. Orogeny D. Epeirogeny Explanation: Gradation is the process of wearing down relief variations on the Earth’s surface through erosion.9 / 209. What is exfoliation? A. The transportation of sediments by glaciers B. The formation of rocks by biological activity C. The flaking off of curved sheets from rocks D. The breakdown of rocks by chemical reactions 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.10 / 2010. What is diastrophism? A. The process of soil formation B. The process of volcanic eruption C. The process of rock formation D. All processes that move, elevate, or build up portions of the Earth's crust Explanation: Diastrophism encompasses all processes that move, elevate, or build up portions of the Earth’s crust.11 / 2011. What is the most common cause of physical weathering? A. Biological activity B. Thermal expansion and pressure release C. Chemical reactions D. Wind erosion Explanation: Most physical weathering processes are caused by thermal expansion and pressure release.12 / 2012. What is the main source of energy for endogenic geomorphic processes? A. Solar energy B. Hydroelectric energy C. Wind energy D. Radioactivity, rotational and tidal friction, and primordial heat 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.13 / 2013. What is orogeny? A. A continent-building process B. A mountain-building process C. A soil formation process D. A volcanic eruption process Explanation: Orogeny is a mountain-building process, whereas epeirogeny is a continent-building process.14 / 2014. What are geomorphic processes? A. The processes that cause earthquakes B. The processes that form rocks C. The processes that drive atmospheric circulation D. The processes that shape the Earth's surface 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.15 / 2015. How do burrowing animals contribute to weathering? A. They transport sediments over long distances. B. They change the Earth's magnetic field. C. They expose new surfaces to chemical attack and assist in the penetration of moisture and air. D. They break down rocks with their teeth. Explanation: Burrowing animals help in exposing new surfaces to chemical attack and assist in the penetration of moisture and air, contributing to weathering.16 / 2016. Which of the following is an endogenic geomorphic process? A. Diastrophism B. Deposition C. Weathering D. Erosion Explanation: Diastrophism and volcanism are endogenic geomorphic processes.17 / 2017. What is the primary role of gravity in geomorphic processes? A. It causes volcanic eruptions. B. It influences the Earth's magnetic field. C. It prevents erosion and deposition. D. It causes stresses on Earth materials and activates downslope movements. Explanation: Gravity not only activates all downslope movements of matter but also causes stresses on Earth materials.18 / 2018. What are exogenic forces? A. Gravitational forces B. Magnetic forces C. Forces originating from within the Earth's atmosphere D. Forces originating from within the Earth Explanation: Exogenic forces are external forces that originate within the Earth’s atmosphere.19 / 2019. What does volcanism include? A. The erosion of rocks by wind B. The formation of glaciers C. The movement of magma onto or toward the Earth's surface D. The deposition of sediments by rivers 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.20 / 2020. What is a geomorphic agent? A. Any exogenic element capable of acquiring and transporting Earth materials B. Any endogenic force causing changes in the Earth's surface C. Any living organism that modifies the Earth's surface D. Any human activity that impacts the Earth's environment Explanation: A geomorphic agent is any exogenic element of nature, like water, ice, or wind, that can acquire and transport Earth materials.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
