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