What is soil? A. A type of rock B. A type of mineral C. A type of fossil 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.2 / 202. What is humus? A. A type of fossil B. The finely divided organic matter of the soil C. A type of rock D. A type of mineral Explanation: Humus is the finely divided organic matter of the soil, derived from dead plants.3 / 203. What is the significance of weathering? A. It breaks down rocks and prepares the way for soil formation and erosion. B. It influences the Earth's climate. C. It creates ocean currents. D. It causes earthquakes. 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.4 / 204. What is the first step in soil formation? A. Erosion B. Weathering C. Volcanic eruption D. Deposition Explanation: Soil formation, or pedogenesis, begins with weathering.5 / 205. What is erosion? A. The acquisition and transportation of rock debris B. The formation of rocks C. The eruption of volcanoes D. The movement of continents Explanation: Erosion involves the acquisition and transportation of rock debris.6 / 206. What is a debris slide? A. The formation of mountains B. Rapid rolling or sliding of earth debris without backward rotation C. A type of earthquake D. The deposition of sediments by rivers Explanation: Rapid rolling or sliding of earth debris without backward rotation of mass is known as debris slide.7 / 207. What is the role of time in soil formation? A. It creates ocean currents. B. It determines the maturation of soils and profile development. C. It influences the Earth's climate. D. It causes earthquakes. Explanation: The length of time that soil-forming processes operate determines the maturation of soils and profile development.8 / 208. What is mass movement? A. The transfer of rock debris down slopes under the direct influence of gravity B. The eruption of volcanoes C. The formation of mountains D. The movement of continents Explanation: Mass movements involve the transfer of rock debris down slopes under the direct influence of gravity.9 / 209. 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 causing earthquakes D. The process of weathering rocks 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. 10 / 2010. What is deposition? A. A consequence of erosion, where sediments settle due to reduced energy B. The formation of rocks by biological activity C. The eruption of volcanoes 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.11 / 2011. How does weathering aid mass wasting? A. It increases the weight of rocks. B. It weakens rocks, making them more susceptible to movement. C. It influences the Earth's magnetic field. D. It changes the Earth's climate. Explanation: Weathering aids mass wasting by weakening rocks and making them more susceptible to movement.12 / 2012. What is a landslide? A. A rapid and perceptible mass movement B. The formation of rivers C. A slow and imperceptible mass movement D. The movement of glaciers Explanation: Landslides are relatively rapid and perceptible movements involving relatively dry materials.13 / 2013. What is the role of water in mass movement? A. It is the primary driving force behind mass movement. B. It can be carried with the debris, but it does not carry debris with it. C. It prevents mass movement. 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.14 / 2014. What is slump? A. Slipping of rock debris with backward rotation B. A type of volcanic eruption C. The erosion of rocks by wind 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.15 / 2015. How does weathering contribute to bio-diversity? A. It creates a variety of habitats for organisms. B. It changes the Earth's climate. C. It releases nutrients into the soil. D. It influences the Earth's magnetic field. Explanation: Biomes and biodiversity are fundamentally a result of forests (vegetation), and forests depend on the depth of weathering mantles.16 / 2016. What is a rockslide? A. Sliding of individual rock masses down bedding, joint, or fault surfaces B. The deposition of sediments by rivers C. A type of earthquake D. The formation of mountains Explanation: Sliding of individual rock masses down bedding, joint, or fault surfaces is rockslide.17 / 2017. What is the importance of weathering in the national economy? A. It influences the Earth's climate. B. It creates employment opportunities. C. It contributes to the development of new technologies. D. It helps in the enrichment and concentration of valuable ores. 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.18 / 2018. What is a debris fall? A. A type of volcanic eruption B. Nearly a free fall of earth debris from a vertical or overhanging face C. The formation of glaciers D. The erosion of rocks by wind Explanation: Debris fall is nearly a free fall of earth debris from a vertical or overhanging face.19 / 2019. What is abrasion? A. The formation of rocks by chemical processes B. The deposition of sediments by rivers C. The wearing down of rocks by the rock debris carried by geomorphic agents D. The movement of glaciers Explanation: Abrasion is the wearing down of rocks by the rock debris carried by geomorphic agents.20 / 2020. What is the basic input for soil formation? A. The weathered material or transported deposits B. Air C. Water D. Magma Explanation: The weathered material or transported deposits form the basic input for soil formation.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
