MCQ Chapter 2 Shaping of the Earth’s Surface Class 9 Social Science CBSE Board Advertisement 1. What does the theory of plate tectonics explain?The movement of ocean currentsThe movement of the Earth's crustThe formation of cloudsThe rotation of the EarthQuestion 1 of 202. Who proposed the theory of plate tectonics?Isaac NewtonCharles DarwinW.J.MorganAlfred WegenerQuestion 2 of 203. What is a natural feature formed on the Earth's surface called?MineralAtmosphereEcosystemLandformQuestion 3 of 204. Which of the following is a landform?PlateauCloudRainbowStarQuestion 4 of 205. Which layer is the outermost part of the Earth?MantleCrustCoreAsthenosphereQuestion 5 of 206. Which is the thickest layer of the Earth?CrustInner coreMantleOuter coreQuestion 6 of 207. Which is the innermost layer of the Earth?LithosphereCrustMantleCoreQuestion 7 of 208. The lithosphere consists of the crust and the:Upper mantleLower mantleOuter coreInner coreQuestion 8 of 209. Which layer beneath the lithosphere allows tectonic plates to move?CrustAsthenosphereCoreContinental shelfQuestion 9 of 2010. Tectonic plates move at a speed of approximately:A few metres per dayA few kilometres per monthA few centimetres per yearA few metres per hourQuestion 10 of 2011. Which type of tectonic plate carries the continents?Oceanic plateMixed plateTransform plateContinental plateQuestion 11 of 2012. Which type of plate carries both continents and oceans?Mixed plateOceanic plateContinental plateMinor plateQuestion 12 of 2013. What causes tectonic plates to move?Ocean tidesConvection currents in the mantleEarth's rotationSolar radiationQuestion 13 of 2014. Convection currents are created because:The Moon pulls the oceans.Wind pushes the crust.The Earth's core heats the mantle.Rainwater enters the mantle.Question 14 of 2015. What are the edges where tectonic plates meet called?Rift valleysFault linesContinental marginsPlate boundariesQuestion 15 of 2016. At a convergent boundary, tectonic plates:Move towards each otherMove away from each otherRemain stationaryMove in circlesQuestion 16 of 2017. The collision of two continental plates mainly forms:Mid-ocean ridgesFold mountainsRiver deltasSand dunesQuestion 17 of 2018. When an oceanic plate collides with a continental plate, the oceanic plate:Breaks into islandsFloats above the continental plateSinks beneath the continental plateStops moving completelyQuestion 18 of 2019. Which type of plate boundary forms new crust as magma rises?Transform boundaryConvergent boundaryFault boundaryDivergent boundaryQuestion 19 of 2020. Which landform is a good example of a feature created at a divergent boundary?HimalayaSan Andreas FaultMid-Atlantic RidgeSundarbans DeltaQuestion 20 of 20 Loading...
