What is the primary role of gravity in geomorphic processes? A. It influences the Earth's magnetic field. B. It causes volcanic eruptions. C. It causes stresses on Earth materials and activates downslope movements. D. It prevents erosion and deposition. Explanation: Gravity not only activates all downslope movements of matter but also causes stresses on Earth materials.2 / 202. What are exogenic forces? A. Forces originating from within the Earth's atmosphere B. Magnetic forces C. Gravitational forces D. Forces originating from within the Earth Explanation: Exogenic forces are external forces that originate within the Earth’s atmosphere.3 / 203. What is the main cause of the reduction in the Earth’s potential to sustain life? A. Climate change B. Natural disasters C. Overuse of resources by humans 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.4 / 204. What is exfoliation? A. The breakdown of rocks by chemical reactions B. The transportation of sediments by glaciers 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.5 / 205. What is a geomorphic agent? A. Any endogenic force causing changes in the Earth's surface B. Any exogenic element capable of acquiring and transporting Earth materials 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.6 / 206. What is diastrophism? A. The process of soil formation B. The process of rock formation C. All processes that move, elevate, or build up portions of the Earth's crust D. The process of volcanic eruption Explanation: Diastrophism encompasses all processes that move, elevate, or build up portions of the Earth’s crust.7 / 207. What is stress in the context of geomorphic processes? A. Force applied per unit area B. The weight of overlying rocks C. The movement of water through rocks D. Temperature changes in rocks Explanation: Stress is the force applied per unit area, produced in a solid by pushing or pulling, which induces deformation.8 / 208. Why is it important to understand the nature of the Earth’s surface? A. To explore space B. To develop new technologies C. To predict earthquakes 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.9 / 209. What are geomorphic processes? A. The processes that form rocks B. The processes that cause earthquakes 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.10 / 2010. What is orogeny? A. A mountain-building process B. A soil formation process C. A volcanic eruption process D. A continent-building process Explanation: Orogeny is a mountain-building process, whereas epeirogeny is a continent-building process.11 / 2011. What is the ultimate source of energy for exogenic processes? A. The sun B. Gravitational forces C. Chemical reactions 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.12 / 2012. How do burrowing animals contribute to weathering? A. They transport sediments over long distances. B. They expose new surfaces to chemical attack and assist in the penetration of moisture and air. C. They break down rocks with their teeth. 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.13 / 2013. What is the primary cause of the uneven surface of the Earth? A. Gravitational forces from the moon B. Internal forces within the Earth 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. 14 / 2014. What are endogenic forces primarily responsible for? A. Transporting sediments B. Building up landforms C. Wearing down landforms D. Creating atmospheric circulation Explanation: Endogenic forces are primarily land-building forces, while exogenic forces are land-wearing forces.15 / 2015. What is the main source of energy for endogenic geomorphic processes? A. Wind energy B. Solar energy C. Radioactivity, rotational and tidal friction, and primordial heat D. Hydroelectric 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.16 / 2016. What is the most common cause of physical weathering? A. Chemical reactions B. Wind erosion C. Biological activity D. Thermal expansion and pressure release Explanation: Most physical weathering processes are caused by thermal expansion and pressure release.17 / 2017. What does volcanism include? A. The movement of magma onto or toward the Earth's surface B. The formation of glaciers 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. Which of the following is an endogenic geomorphic process? A. Diastrophism B. Weathering C. Erosion D. Deposition Explanation: Diastrophism and volcanism are endogenic geomorphic processes.19 / 2019. What is the phenomenon of wearing down relief variations on the Earth’s surface called? A. Denudation B. Orogeny C. Gradation D. Epeirogeny Explanation: Gradation is the process of wearing down relief variations on the Earth’s surface through erosion.20 / 2020. What is biological weathering? A. The contribution to or removal of minerals and ions from the weathering environment due to organisms B. The breakdown of rocks by wind C. The formation of rocks by chemical processes 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.
