What is the main cause of the reduction in the Earth’s potential to sustain life? A. Natural disasters B. Overuse of resources by humans C. Volcanic eruptions D. Climate change 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.4 / 204. How do burrowing animals contribute to weathering? A. They transport sediments over long distances. B. They change the Earth's magnetic field. C. They break down rocks with their teeth. D. They expose new surfaces to chemical attack and assist in the penetration of moisture and air. Explanation: Burrowing animals help in exposing new surfaces to chemical attack and assist in the penetration of moisture and air, contributing to weathering.5 / 205. What is the primary cause of the uneven surface of the Earth? A. Internal forces within the Earth B. Gravitational forces from the moon C. External forces from the atmosphere D. Sunlight Explanation: The variations in the Earth’s outer surface are primarily due to the differences in internal forces operating from within the Earth. 6 / 206. What does volcanism include? A. The movement of magma onto or toward the Earth's surface B. The erosion of rocks by wind C. The deposition of sediments by rivers D. The formation of glaciers 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.7 / 207. What is diastrophism? A. All processes that move, elevate, or build up portions of the Earth's crust B. The process of rock formation C. The process of soil formation D. The process of volcanic eruption Explanation: Diastrophism encompasses all processes that move, elevate, or build up portions of the Earth’s crust.8 / 208. What is the ultimate source of energy for exogenic processes? A. Gravitational forces B. Chemical reactions C. The Earth's internal heat D. The sun Explanation: Exogenic processes derive their energy from the atmosphere, which is determined by the ultimate energy from the sun.9 / 209. What is the phenomenon of wearing down relief variations on the Earth’s surface called? A. Epeirogeny B. Orogeny C. Denudation D. Gradation Explanation: Gradation is the process of wearing down relief variations on the Earth’s surface through erosion.10 / 2010. What is a geomorphic agent? A. Any human activity that impacts the Earth's environment B. Any living organism that modifies the Earth's surface C. Any exogenic element capable of acquiring and transporting Earth materials D. Any endogenic force causing changes in 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.11 / 2011. What is the main source of energy for endogenic geomorphic processes? A. Radioactivity, rotational and tidal friction, and primordial heat B. Wind energy C. Hydroelectric energy D. Solar 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.12 / 2012. What are exogenic forces? A. Magnetic forces B. Forces originating from within the Earth's atmosphere C. Gravitational forces D. Forces originating from within the Earth Explanation: Exogenic forces are external forces that originate within the Earth’s atmosphere.13 / 2013. What is stress in the context of geomorphic processes? A. The movement of water through rocks B. Temperature changes in rocks C. The weight of overlying rocks D. Force applied per unit area Explanation: Stress is the force applied per unit area, produced in a solid by pushing or pulling, which induces deformation.14 / 2014. Why is it important to understand the nature of the Earth’s surface? A. To predict earthquakes B. To develop new technologies C. To explore space D. To use it effectively without disturbing its balance 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.15 / 2015. What is biological weathering? A. The breakdown of rocks by wind B. The transportation of sediments by rivers C. The formation of rocks by chemical processes 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. 16 / 2016. What is the most common cause of physical weathering? A. Thermal expansion and pressure release B. Biological activity C. Wind erosion D. Chemical reactions Explanation: Most physical weathering processes are caused by thermal expansion and pressure release.17 / 2017. What is exfoliation? A. The flaking off of curved sheets from rocks B. The transportation of sediments by glaciers C. The formation of rocks by biological activity 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.18 / 2018. What is the primary role of gravity in geomorphic processes? A. It prevents erosion and deposition. B. It causes volcanic eruptions. C. It influences the Earth's magnetic field. 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.19 / 2019. What are geomorphic processes? A. The processes that drive atmospheric circulation B. The processes that cause earthquakes C. The processes that form rocks 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.20 / 2020. What is orogeny? A. A mountain-building process B. A volcanic eruption process C. A soil formation process D. A continent-building process Explanation: Orogeny is a mountain-building process, whereas epeirogeny is a continent-building process.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
