What is nitrogen fixation? A. The process of causing earthquakes B. The process of converting gaseous nitrogen into a chemical form usable by plants C. The process of forming mountains 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. 2 / 202. What is deposition? A. A consequence of erosion, where sediments settle due to reduced energy B. The movement of continents C. The eruption of volcanoes D. The formation of rocks by biological activity 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 a debris slide? A. A type of earthquake B. The deposition of sediments by rivers C. Rapid rolling or sliding of earth debris without backward rotation D. The formation of mountains Explanation: Rapid rolling or sliding of earth debris without backward rotation of mass is known as debris slide.4 / 204. What is mass movement? A. The eruption of volcanoes B. The formation of mountains C. The transfer of rock debris down slopes under the direct influence of gravity D. The movement of continents Explanation: Mass movements involve the transfer of rock debris down slopes under the direct influence of gravity.5 / 205. What is abrasion? A. The movement of glaciers B. The formation of rocks by chemical processes 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.6 / 206. What is the role of time in soil formation? A. It determines the maturation of soils and profile development. B. It influences the Earth's climate. C. It causes earthquakes. D. It creates ocean currents. Explanation: The length of time that soil-forming processes operate determines the maturation of soils and profile development.7 / 207. What is the importance of weathering in the national economy? A. It creates employment opportunities. B. It helps in the enrichment and concentration of valuable ores. C. It influences the Earth's climate. D. It contributes to the development of new technologies. 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.8 / 208. What is a landslide? A. A rapid and perceptible mass movement B. The formation of rivers C. The movement of glaciers D. A slow and imperceptible mass movement Explanation: Landslides are relatively rapid and perceptible movements involving relatively dry materials.9 / 209. 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.10 / 2010. What is the significance of weathering? A. It influences the Earth's climate. B. It causes earthquakes. C. It creates ocean currents. D. It breaks down rocks and prepares the way for soil formation and erosion. 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.11 / 2011. What is the first step in soil formation? A. Weathering B. Erosion C. Deposition D. Volcanic eruption Explanation: Soil formation, or pedogenesis, begins with weathering.12 / 2012. 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.13 / 2013. 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.14 / 2014. What is soil? A. A dynamic medium in which many chemical, physical, and biological activities occur B. A type of rock C. A type of mineral D. A type of fossil Explanation: Soil is a dynamic medium where various chemical, physical, and biological activities constantly take place.15 / 2015. What is humus? A. A type of mineral B. The finely divided organic matter of the soil C. A type of rock D. A type of fossil Explanation: Humus is the finely divided organic matter of the soil, derived from dead plants.16 / 2016. What is erosion? A. The eruption of volcanoes B. The formation of rocks C. The acquisition and transportation of rock debris D. The movement of continents Explanation: Erosion involves the acquisition and transportation of rock debris.17 / 2017. What is the role of water in mass movement? A. It is the primary driving force behind mass movement. B. It prevents 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.18 / 2018. What is slump? A. A type of volcanic eruption B. The formation of glaciers C. The erosion of rocks by wind 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.19 / 2019. How does weathering aid mass wasting? A. It influences the Earth's magnetic field. B. It increases the weight of rocks. 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.20 / 2020. How does weathering contribute to bio-diversity? A. It releases nutrients into the soil. B. It changes the Earth's climate. C. It influences the Earth's magnetic field. D. It creates a variety of habitats for organisms. Explanation: Biomes and biodiversity are fundamentally a result of forests (vegetation), and forests depend on the depth of weathering mantles.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
