What is the term for the process by which water changes from a gas to a liquid? A. Sublimation B. Condensation C. Precipitation D. Evaporation Explanation: Condensation is the process by which water vapor in the atmosphere changes into liquid water, forming clouds and eventually leading to precipitation.2 / 202. Which of the following is NOT a significant factor influencing the temperature of ocean currents? A. Prevailing winds B. Water depth C. Ocean currents D. Latitude Explanation: While water depth influences the vertical distribution of temperature, the major factors affecting the temperature of ocean currents are latitude, prevailing winds, and the interaction of different currents.3 / 203. Which of the following is NOT a major factor influencing the salinity of ocean water? A. Evaporation B. Water temperature C. Precipitation D. Ocean currents Explanation: While water temperature can indirectly influence salinity, the primary factors affecting ocean salinity are evaporation, precipitation, and ocean currents.4 / 204. What is the name for the process by which cold, nutrient-rich water rises from the depths to the surface? A. Downwelling B. Convection C. Upwelling D. Subduction Explanation: Upwelling is the process in which cold, nutrient-rich water from the deeper ocean rises to the surface, replacing warmer surface water that has been pushed away by winds or currents.5 / 205. What is the term for the total content of dissolved salts in seawater? A. Pressure B. Density C. Salinity D. Temperature Explanation: Salinity refers to the total amount of dissolved salts in seawater, typically expressed in parts per thousand.6 / 206. What is the primary driving force behind ocean currents? A. All of the above B. Salinity differences C. Wind D. Temperature differences Explanation: Ocean currents are driven by a combination of factors, including wind patterns, variations in salinity, and temperature differences between different parts of the ocean.7 / 207. What is the term for the process by which water changes from a solid to a liquid? A. Condensation B. Melting C. Freezing D. Evaporation Explanation: Melting is the process by which water changes from a solid state (ice) to a liquid state, primarily due to the input of heat energy.8 / 208. Which of the following is NOT a characteristic feature of submarine canyons? A. Deep, steep-sided valleys B. Formation by turbidity currents C. Extension from the mouths of large rivers D. Flat-topped summits Explanation: Submarine canyons are characterized by deep, steep-sided valleys, formation by turbidity currents, and extension from the mouths of large rivers. Flat-topped summits are characteristic of guyots, not submarine canyons.9 / 209. Which of the following is NOT a characteristic feature of mid-oceanic ridges? A. Deep, narrow trenches B. Two chains of mountains separated by a large depression C. Peaks as high as 2,500 meters D. Formation of new oceanic crust Explanation: Mid-oceanic ridges are characterized by two chains of mountains separated by a large depression, peaks as high as 2,500 meters, and the formation of new oceanic crust. Deep, narrow trenches are associated with oceanic deeps, not mid-oceanic ridges.10 / 2010. What is the term for the layer in the ocean where density increases rapidly with depth? A. Thermocline B. Halocline C. Isocline D. Pycnocline Explanation: The pycnocline is the zone in the ocean where density changes abruptly with depth, primarily due to changes in temperature and salinity.11 / 2011. What is the term for the process by which water vapor changes directly into ice, bypassing the liquid phase? A. Condensation B. Precipitation C. Deposition D. Evaporation Explanation: Deposition is the process by which water vapor in the atmosphere changes directly into ice, such as the formation of frost or snow.12 / 2012. Which ocean is the second largest of the major oceans? A. Atlantic Ocean B. Indian Ocean C. Pacific Ocean D. Arctic Ocean Explanation: The Atlantic Ocean is the second largest ocean on Earth, covering approximately 20% of the planet’s surface.13 / 2013. What is the term for the process by which warm, nutrient-depleted water sinks from the surface to the depths? A. Subduction B. Upwelling C. Downwelling D. Convection Explanation: Downwelling is the process in which warmer, nutrient-depleted water from the surface sinks to the deeper ocean, replacing colder, denser water that has risen through upwelling.14 / 2014. What is the term for the flattest and smoothest regions of the ocean floor? A. Continental slopes B. Continental shelves C. Oceanic deeps D. Deep sea plains Explanation: Deep sea plains are vast, flat areas of the ocean floor that cover a significant portion of the ocean basins.15 / 2015. What is the term for any form of water that falls from the atmosphere to the Earth’s surface? A. Precipitation B. Condensation C. Evaporation D. Sublimation Explanation: Precipitation encompasses any form of water that falls from the atmosphere to the Earth’s surface, including rain, snow, sleet, and hail.16 / 2016. Which of the following is NOT a major component of the dissolved salts in seawater? A. Potassium nitrate B. Sodium chloride C. Calcium sulfate D. Magnesium chloride Explanation: The major components of dissolved salts in seawater include sodium chloride, magnesium chloride, and calcium sulfate. Potassium nitrate is not a significant component.17 / 2017. Which ocean is the smallest and shallowest of the major oceans? A. Arctic Ocean B. Indian Ocean C. Pacific Ocean D. Atlantic Ocean Explanation: The Arctic Ocean is the smallest and shallowest of the major oceans, located primarily in the Arctic region.18 / 2018. Which of the following is NOT a major factor affecting the distribution of salinity in ocean waters? A. Latitude B. Water depth C. Prevailing winds D. Ocean currents Explanation: While water depth influences the vertical distribution of salinity, the major factors affecting the overall salinity distribution in oceans are latitude, prevailing winds, and ocean currents.19 / 2019. Which of the following is NOT a major factor affecting the distribution of temperature in ocean waters? A. Water depth B. Prevailing winds C. Latitude D. Ocean currents Explanation: While water depth influences the vertical distribution of temperature, the major factors affecting the overall temperature distribution in oceans are latitude, ocean currents, and prevailing winds.20 / 2020. What is the name for the underwater valleys that cut across continental shelves and slopes? A. Guyots B. Atolls C. Canyons D. Seamounts Explanation: Submarine canyons are deep, steep-sided valleys that cut across continental shelves and slopes, often extending from the mouths of large rivers.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
