What is abrasion? A. The formation of rocks by chemical processes B. The movement of glaciers C. The deposition of sediments by rivers D. The wearing down of rocks by the rock debris carried by geomorphic agents Explanation: Abrasion is the wearing down of rocks by the rock debris carried by geomorphic agents.2 / 202. What is deposition? A. The formation of rocks by biological activity B. The eruption of volcanoes C. A consequence of erosion, where sediments settle due to reduced energy D. The movement of continents Explanation: Deposition is a consequence of erosion, where the erosional agents lose their velocity and energy on gentler slopes, causing the carried materials to settle.3 / 203. What is humus? A. A type of rock B. A type of fossil C. A type of mineral D. The finely divided organic matter of the soil Explanation: Humus is the finely divided organic matter of the soil, derived from dead plants.4 / 204. What is the role of water in mass movement? A. It prevents mass movement. B. It is the primary driving force behind mass movement. C. It has no role in mass movement. D. It can be carried with the debris, but it does not carry debris with it. Explanation: In mass movements, air, water, or ice do not carry debris with them from place to place, but the debris may carry air, water, or ice with it.5 / 205. What is the significance of weathering? A. It breaks down rocks and prepares the way for soil formation and erosion. B. It creates ocean currents. C. It causes earthquakes. D. It influences the Earth's climate. Explanation: Weathering processes are responsible for breaking down rocks into smaller fragments, preparing the way for the formation of regolith, soils, and enabling erosion and mass movements.6 / 206. What is a landslide? A. A rapid and perceptible mass movement B. A slow and imperceptible mass movement C. The formation of rivers D. The movement of glaciers Explanation: Landslides are relatively rapid and perceptible movements involving relatively dry materials.7 / 207. What is mass movement? A. The formation of mountains B. The eruption of volcanoes C. The movement of continents D. The transfer of rock debris down slopes under the direct influence of gravity Explanation: Mass movements involve the transfer of rock debris down slopes under the direct influence of gravity.8 / 208. What is erosion? A. The acquisition and transportation of rock debris B. The formation of rocks C. The movement of continents D. The eruption of volcanoes Explanation: Erosion involves the acquisition and transportation of rock debris.9 / 209. What is slump? A. The erosion of rocks by wind B. Slipping of rock debris with backward rotation C. A type of volcanic eruption D. The formation of glaciers Explanation: Slump is the slipping of one or several units of rock debris with a backward rotation with respect to the slope over which the movement takes place.10 / 2010. How does weathering aid mass wasting? A. It changes the Earth's climate. B. It influences the Earth's magnetic field. C. It weakens rocks, making them more susceptible to movement. D. It increases the weight of rocks. Explanation: Weathering aids mass wasting by weakening rocks and making them more susceptible to movement.11 / 2011. What is a rockslide? A. Sliding of individual rock masses down bedding, joint, or fault surfaces B. A type of earthquake C. The formation of mountains D. The deposition of sediments by rivers Explanation: Sliding of individual rock masses down bedding, joint, or fault surfaces is rockslide.12 / 2012. How does weathering contribute to bio-diversity? A. It influences the Earth's magnetic field. B. It creates a variety of habitats for organisms. C. It releases nutrients into the soil. D. It changes the Earth's climate. Explanation: Biomes and biodiversity are fundamentally a result of forests (vegetation), and forests depend on the depth of weathering mantles.13 / 2013. What is the role of time in soil formation? A. It causes earthquakes. B. It determines the maturation of soils and profile development. C. It influences the Earth's climate. D. It creates ocean currents. Explanation: The length of time that soil-forming processes operate determines the maturation of soils and profile development.14 / 2014. What is the importance of weathering in the national economy? A. It contributes to the development of new technologies. B. It helps in the enrichment and concentration of valuable ores. C. It influences the Earth's climate. D. It creates employment opportunities. Explanation: Weathering of rocks and deposits helps in the enrichment and concentration of certain valuable ores of iron, manganese, aluminum, copper, etc., which are of great importance for the national economy.15 / 2015. What is soil? A. A type of fossil B. A type of mineral C. A type of rock D. A dynamic medium in which many chemical, physical, and biological activities occur Explanation: Soil is a dynamic medium where various chemical, physical, and biological activities constantly take place.16 / 2016. What is the basic input for soil formation? A. Air B. Magma C. Water D. The weathered material or transported deposits Explanation: The weathered material or transported deposits form the basic input for soil formation.17 / 2017. What is nitrogen fixation? A. The process of forming mountains B. The process of converting gaseous nitrogen into a chemical form usable by plants C. The process of weathering rocks D. The process of causing earthquakes Explanation: Nitrogen fixation is the process by which bacteria and other soil organisms convert gaseous nitrogen from the air into a chemical form that can be used by plants. 18 / 2018. What is a debris fall? A. The erosion of rocks by wind B. A type of volcanic eruption C. The formation of glaciers D. Nearly a free fall of earth debris from a vertical or overhanging face Explanation: Debris fall is nearly a free fall of earth debris from a vertical or overhanging face.19 / 2019. What is the first step in soil formation? A. Deposition B. Volcanic eruption C. Weathering D. Erosion Explanation: Soil formation, or pedogenesis, begins with weathering.20 / 2020. What is a debris slide? A. The formation of mountains B. A type of earthquake C. The deposition of sediments by rivers D. Rapid rolling or sliding of earth debris without backward rotation Explanation: Rapid rolling or sliding of earth debris without backward rotation of mass is known as debris slide.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
