What is humus? A. A type of mineral B. A type of rock C. The finely divided organic matter of the soil D. A type of fossil Explanation: Humus is the finely divided organic matter of the soil, derived from dead plants.2 / 202. What is the first step in soil formation? A. Volcanic eruption B. Deposition C. Erosion D. Weathering Explanation: Soil formation, or pedogenesis, begins with weathering.3 / 203. 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.4 / 204. What is abrasion? A. The movement of glaciers B. The wearing down of rocks by the rock debris carried by geomorphic agents C. The formation of rocks by chemical processes D. The deposition of sediments by rivers Explanation: Abrasion is the wearing down of rocks by the rock debris carried by geomorphic agents.5 / 205. 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.6 / 206. What is a rockslide? A. A type of earthquake B. Sliding of individual rock masses down bedding, joint, or fault surfaces C. The deposition of sediments by rivers D. The formation of mountains Explanation: Sliding of individual rock masses down bedding, joint, or fault surfaces is rockslide.7 / 207. What is mass movement? A. The transfer of rock debris down slopes under the direct influence of gravity B. The formation of mountains C. The eruption of volcanoes D. The movement of continents Explanation: Mass movements involve the transfer of rock debris down slopes under the direct influence of gravity.8 / 208. What is deposition? A. The formation of rocks by biological activity B. A consequence of erosion, where sediments settle due to reduced energy 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.9 / 209. How does weathering contribute to bio-diversity? A. It changes the Earth's climate. B. It influences the Earth's magnetic field. C. It releases nutrients into the soil. 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.10 / 2010. What is a landslide? A. The formation of rivers B. A slow and imperceptible mass movement C. A rapid and perceptible mass movement D. The movement of glaciers Explanation: Landslides are relatively rapid and perceptible movements involving relatively dry materials.11 / 2011. What is a debris fall? A. The erosion of rocks by wind B. Nearly a free fall of earth debris from a vertical or overhanging face C. A type of volcanic eruption D. The formation of glaciers Explanation: Debris fall is nearly a free fall of earth debris from a vertical or overhanging face.12 / 2012. 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 mineral D. A type of rock Explanation: Soil is a dynamic medium where various chemical, physical, and biological activities constantly take place.13 / 2013. 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 influences the Earth's climate. 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.14 / 2014. How does weathering aid mass wasting? A. It influences the Earth's magnetic field. B. It weakens rocks, making them more susceptible to movement. C. It changes the Earth's climate. D. It increases the weight of rocks. Explanation: Weathering aids mass wasting by weakening rocks and making them more susceptible to movement.15 / 2015. What is the importance of weathering in the national economy? A. It helps in the enrichment and concentration of valuable ores. B. It contributes to the development of new technologies. 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.16 / 2016. What is erosion? A. The formation of rocks B. The acquisition and transportation of rock debris C. The movement of continents D. The eruption of volcanoes Explanation: Erosion involves the acquisition and transportation of rock debris.17 / 2017. What is the role of time in soil formation? A. It creates ocean currents. B. It causes earthquakes. C. It determines the maturation of soils and profile development. 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.18 / 2018. 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.19 / 2019. What is slump? A. Slipping of rock debris with backward rotation B. The formation of glaciers C. The erosion of rocks by wind D. A type of volcanic eruption 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.20 / 2020. 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 weathering rocks D. The process of forming mountains 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.
