What force keeps objects from floating into space?Centrifugal forceMagnetic forceGravitational forceTidal forceQuestion 1 of 202. What is the approximate difference in time between two high tides?6 hours8 hours12 hours and 25 minutes24 hoursQuestion 2 of 203. What type of energy do waves transfer to the coast?Light energyKinetic energyNuclear energyMagnetic energyQuestion 3 of 204. Which phase of the moon results in a neap tide?New moonFull moonFirst and third quarterWaning gibbousQuestion 4 of 205. Why do tidal timings change daily?Because of seasonal variationsBecause the moon moves ahead slightly each dayBecause the Earth's gravity weakens dailyBecause of variations in ocean depthQuestion 5 of 206. What is a key feature of a tsunami?It occurs due to strong windsIt has extremely high wavesIt occurs only in the Pacific OceanIt happens every dayQuestion 6 of 207. Which factor influences the height of waves?The speed and direction of the windThe depth of the oceanThe temperature of the waterThe presence of marine lifeQuestion 7 of 208. What should one do if an earthquake occurs in the ocean?Move toward the coastlineStay in the waterMove to higher ground away from the coastWait near the beachQuestion 8 of 209. What happens to water when the wind blows over it?It remains stillIt forms wavesIt flows in the opposite directionIt sinksQuestion 9 of 2010. What is the vertical distance between a wave crest and the following trough called?Wave heightWavelengthAmplitudeVelocityQuestion 10 of 2011. What is the effect of tides on salt production?Tides wash away salt pansSea water can be stored in salt pans during high tideSalt production stops during high tideSalt forms only during low tideQuestion 11 of 2012. What determines the wavelength of ocean waves?The depth of the oceanThe velocity of the windThe gravitational force of the moonThe presence of marine organismsQuestion 12 of 2013. Which of the following is a positive effect of tides?They prevent fish from entering shallow watersThey help clear waste from coastal areasThey make ports inaccessibleThey stop ships from dockingQuestion 13 of 2014. How do tides assist in generating electricity?They increase ocean temperaturesThey produce kinetic energy that can be harnessedThey create magnetic fieldsThey reduce the salinity of waterQuestion 14 of 2015. What is the term used for the raised portion of a wave?TroughCrestAmplitudeWavelengthQuestion 15 of 2016. What happens to wave height when strong winds blow in one direction?Wave height decreasesWaves become smallerLarge waves are generatedWaves disappear completelyQuestion 16 of 2017. How does the moon’s position influence high tide?High tide occurs when the moon is at a right angle to the EarthHigh tide occurs when the moon is directly overhead or on the opposite side of the EarthHigh tide occurs only during daytimeThe moon has no effect on tidesQuestion 17 of 2018. What is the approximate time difference between two successive low tides?6 hours8 hours12 hours and 25 minutes24 hoursQuestion 18 of 2019. What is the primary force responsible for ocean waves?Earth's rotationThe moon’s gravitational pullWind energyThe tilt of Earth's axisQuestion 19 of 2020. Which of the following is a dangerous effect of tides?They improve fishingThey help maintain coastal biodiversityThey can cause accidents for swimmers unaware of tidal timingsThey help in clearing coastal wasteQuestion 20 of 20 Loading...
