What is mass movement? A. The eruption of volcanoes B. The formation of mountains 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.2 / 202. 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.3 / 203. 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 creates ocean currents. D. It influences the Earth's climate. Explanation: The length of time that soil-forming processes operate determines the maturation of soils and profile development.4 / 204. What is the importance of weathering in the national economy? A. It creates employment opportunities. B. It contributes to the development of new technologies. C. It helps in the enrichment and concentration of valuable ores. D. It influences the Earth's climate. 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.5 / 205. How does weathering aid mass wasting? A. It increases the weight of rocks. B. It influences the Earth's magnetic field. C. It changes the Earth's climate. D. It weakens rocks, making them more susceptible to movement. Explanation: Weathering aids mass wasting by weakening rocks and making them more susceptible to movement.6 / 206. What is the first step in soil formation? A. Weathering B. Deposition C. Erosion D. Volcanic eruption Explanation: Soil formation, or pedogenesis, begins with weathering.7 / 207. What is erosion? A. The movement of continents B. The acquisition and transportation of rock debris C. The formation of rocks D. The eruption of volcanoes Explanation: Erosion involves the acquisition and transportation of rock debris.8 / 208. What is slump? A. The erosion of rocks by wind B. A type of volcanic eruption C. The formation of glaciers D. Slipping of rock debris with backward rotation 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.9 / 209. What is humus? A. The finely divided organic matter of the soil B. A type of fossil C. A type of mineral D. A type of rock Explanation: Humus is the finely divided organic matter of the soil, derived from dead plants.10 / 2010. What is soil? A. A type of fossil B. A dynamic medium in which many chemical, physical, and biological activities occur C. A type of rock D. A type of mineral Explanation: Soil is a dynamic medium where various chemical, physical, and biological activities constantly take place.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. What is a debris slide? A. The formation of mountains B. The deposition of sediments by rivers C. A type of earthquake 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.13 / 2013. What is the basic input for soil formation? A. Air B. The weathered material or transported deposits C. Water D. Magma Explanation: The weathered material or transported deposits form the basic input for soil formation.14 / 2014. What is abrasion? A. The movement of glaciers B. The wearing down of rocks by the rock debris carried by geomorphic agents C. The deposition of sediments by rivers D. The formation of rocks by chemical processes Explanation: Abrasion is the wearing down of rocks by the rock debris carried by geomorphic agents.15 / 2015. How does weathering contribute to bio-diversity? A. It influences the Earth's magnetic field. B. It changes the Earth's climate. C. It creates a variety of habitats for organisms. D. It releases nutrients into the soil. Explanation: Biomes and biodiversity are fundamentally a result of forests (vegetation), and forests depend on the depth of weathering mantles.16 / 2016. 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.17 / 2017. What is deposition? A. The eruption of volcanoes B. The formation of rocks by biological activity 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.18 / 2018. 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. 19 / 2019. 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 can be carried with the debris, but it does not carry debris with it. D. It has no role in mass movement. 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.20 / 2020. What is a debris fall? A. The erosion of rocks by wind B. The formation of glaciers C. Nearly a free fall of earth debris from a vertical or overhanging face D. A type of volcanic eruption Explanation: Debris fall is nearly a free fall of earth debris from a vertical or overhanging face.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 95% 0% Restart quiz Category: Class 11 Geography Quizzes in English
