What is stress in the context of geomorphic processes? A. The weight of overlying rocks B. Temperature changes in rocks C. The movement of water through 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.2 / 202. 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 formation of glaciers 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.3 / 203. How do burrowing animals contribute to weathering? A. They transport sediments over long distances. B. They break down rocks with their teeth. C. They expose new surfaces to chemical attack and assist in the penetration of moisture and air. D. They change the Earth's magnetic field. Explanation: Burrowing animals help in exposing new surfaces to chemical attack and assist in the penetration of moisture and air, contributing to weathering.4 / 204. What are exogenic forces? A. Forces originating from within the Earth B. Forces originating from within the Earth's atmosphere C. Magnetic forces D. Gravitational forces Explanation: Exogenic forces are external forces that originate within the Earth’s atmosphere.5 / 205. 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.6 / 206. What is the primary role of gravity in geomorphic processes? A. It influences the Earth's magnetic field. B. It prevents erosion and deposition. C. It causes volcanic eruptions. 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.7 / 207. What are endogenic forces primarily responsible for? A. Wearing down landforms B. Creating atmospheric circulation C. Transporting sediments D. Building up landforms Explanation: Endogenic forces are primarily land-building forces, while exogenic forces are land-wearing forces.8 / 208. What is the main source of energy for endogenic geomorphic processes? A. Wind energy B. Hydroelectric energy C. Radioactivity, rotational and tidal friction, and primordial heat 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.9 / 209. What is diastrophism? A. The process of soil formation B. The process of rock formation C. The process of volcanic eruption 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.10 / 2010. What is the primary cause of the uneven surface of the Earth? A. Internal forces within the Earth B. External forces from the atmosphere C. Gravitational forces from the moon 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. 11 / 2011. What is a geomorphic agent? A. Any human activity that impacts the Earth's environment B. Any exogenic element capable of acquiring and transporting Earth materials C. Any living organism that modifies the Earth's surface 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.12 / 2012. What is the most common cause of physical weathering? A. Biological activity B. Chemical reactions C. Wind erosion D. Thermal expansion and pressure release Explanation: Most physical weathering processes are caused by thermal expansion and pressure release.13 / 2013. What is the phenomenon of wearing down relief variations on the Earth’s surface called? A. Orogeny B. Denudation C. Epeirogeny D. Gradation Explanation: Gradation is the process of wearing down relief variations on the Earth’s surface through erosion.14 / 2014. What is exfoliation? A. The transportation of sediments by glaciers B. The flaking off of curved sheets from rocks 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.15 / 2015. What is the ultimate source of energy for exogenic processes? A. Chemical reactions B. The sun C. Gravitational forces D. The Earth's internal heat Explanation: Exogenic processes derive their energy from the atmosphere, which is determined by the ultimate energy from the sun.16 / 2016. What is the main cause of the reduction in the Earth’s potential to sustain life? A. Volcanic eruptions B. Natural disasters C. Overuse of resources by humans 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.17 / 2017. 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. 18 / 2018. Why is it important to understand the nature of the Earth’s surface? A. To predict earthquakes B. To develop new technologies C. To use it effectively without disturbing its balance D. To explore space 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.19 / 2019. What is orogeny? A. A continent-building process B. A volcanic eruption process C. A mountain-building process D. A soil formation process Explanation: Orogeny is a mountain-building process, whereas epeirogeny is a continent-building process.20 / 2020. Which of the following is an endogenic geomorphic process? A. Deposition B. Erosion C. Weathering D. Diastrophism Explanation: Diastrophism and volcanism are 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 53% 0% Restart quiz Category: Class 11 Geography Quizzes in English
