What is the primary factor that drives deep-water currents? A. Coriolis force B. Wind C. Tides D. Density and gravity Explanation: Variations in water density, caused by differences in temperature and salinity, create the gradients that drive deep-water currents.2 / 202. What is the primary source of energy for waves? A. Tides B. Upwelling of cold water C. Ocean currents D. Wind Explanation: Wind transfers its energy to the water, creating waves.3 / 203. What is half the wave height called? A. Wave period B. Wave height C. Wave amplitude D. Wavelength Explanation: Wave amplitude is half the vertical distance between the crest and trough.4 / 204. What are the major factors that influence the direction and flow of major ocean currents? A. Tides and salinity B. Prevailing winds and Coriolis force C. Temperature and density D. Upwelling and downwelling Explanation: The direction and strength of winds, along with the Coriolis effect caused by Earth’s rotation, shape the patterns of major ocean currents.5 / 205. What are cold currents? A. Currents that are influenced by tides only B. Currents that have no specific temperature C. Currents that bring warm water into cold water areas D. Currents that bring cold water into warm water areas Explanation: Cold currents transport colder water from higher latitudes towards lower latitudes.6 / 206. What is the approximate time between two successive high tides? A. 24 hours B. 12 hours C. 6 hours D. 1 hour Explanation: In most places, there are approximately 12 hours between two consecutive high tides.7 / 207. What is the number of waves passing a given point in one second called? A. Wave speed B. Wave frequency C. Wave height D. Wave amplitude Explanation: Wave frequency is the number of complete waves that pass a specific point in one second.8 / 208. What is the lowest point of a wave called? A. Amplitude B. Wavelength C. Trough D. Crest Explanation: The trough is the bottom or lowest point of a wave.9 / 209. What is the vertical distance between the crest and trough of a wave called? A. Wave amplitude B. Wavelength C. Wave period D. Wave height Explanation: Wave height is the vertical measurement from the lowest point of a trough to the highest point of a crest.10 / 2010. What are warm currents? A. Currents that are influenced by tides only B. Currents that bring warm water into cold water areas C. Currents that have no specific temperature D. Currents that bring cold water into warm water areas Explanation: Warm currents carry warmer water from lower latitudes towards higher latitudes.11 / 2011. What is the primary cause of tidal bulges on Earth? A. Wind B. Upwelling of cold water C. Gravitational pull of the moon and centrifugal force D. Ocean currents Explanation: The gravitational pull of the moon creates a bulge on the side of Earth facing the moon, while centrifugal force causes a bulge on the opposite side.12 / 2012. How do ocean currents affect the climate of coastal areas? A. They influence temperature, precipitation, and humidity. B. They only affect the temperature of coastal areas. C. They only affect the precipitation patterns of coastal areas. D. They have no effect on climate. Explanation: Ocean currents play a significant role in moderating or enhancing temperature and precipitation patterns in coastal regions, depending on whether the currents are warm or cold.13 / 2013. What percentage of ocean water is involved in deep-water currents? A. 10% B. 90% C. 50% D. 100% Explanation: Deep-water currents account for the majority of the water movement in the oceans.14 / 2014. What are the two main types of ocean currents based on depth? A. Surface currents and deep-water currents B. Gyres and eddies C. Tidal currents and wind-driven currents D. Cold currents and warm currents Explanation: Surface currents occur in the upper layers of the ocean, while deep-water currents flow in the deeper parts of the ocean basins.15 / 2015. What percentage of ocean water is involved in surface currents? A. 90% B. 50% C. 10% D. 100% Explanation: Surface currents make up a relatively small portion of the total ocean water volume.16 / 2016. What is the general pattern of oceanic circulation in the middle latitudes? A. Primarily anticyclonic B. Random and unpredictable C. Primarily cyclonic D. No specific pattern Explanation: In the middle latitudes, ocean currents tend to flow in a clockwise pattern in the Northern Hemisphere and counterclockwise in the Southern Hemisphere.17 / 2017. What is the rate at which a wave moves through the water called? A. Wave frequency B. Wave speed C. Wave amplitude D. Wave height Explanation: Wave speed is the rate at which a wave travels through the water, usually measured in knots.18 / 2018. What is the Bay of Fundy known for? A. Having the largest tides in the world B. Having the smallest tides in the world C. Having no tides at all D. Having only one tide per day Explanation: The Bay of Fundy in Canada experiences the most extreme tides globally, with a tidal range of up to 16 meters.19 / 2019. What are tidal currents? A. Deep-water currents B. Currents caused by temperature differences C. Tides that are channeled between islands or into bays and estuaries D. Currents caused by wind Explanation: Tidal currents are formed when the regular rise and fall of tides are constricted by land features, creating strong currents.20 / 2020. How do ocean currents affect marine life? A. They only affect the distribution of fish populations. B. They have no effect on marine life. C. They only affect the migration patterns of marine animals. D. They influence the distribution of nutrients and oxygen, affecting marine ecosystems. Explanation: Ocean currents transport nutrients and oxygen, which are essential for marine life, and create mixing zones where diverse ecosystems thrive.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
