MCQ Chapter 2 Geography Class 11 Maharashtra Board Weathering and Mass Wasting 1. What are the three types of rocks found on Earth?Sedimentary, metamorphic, volcanicIgneous, sedimentary, metamorphicGranite, limestone, quartziteBasalt, sandstone, shaleQuestion 1 of 202. Which type of rock is formed first on Earth’s surface?SedimentaryMetamorphicIgneousLimestoneQuestion 2 of 203. How are sedimentary rocks formed?From cooling lavaUnder immense heat and pressureBy deposition and cementing of sediment layersThrough chemical reactions with oxygenQuestion 3 of 204. Which type of rock breaks more easily compared to others?IgneousSedimentaryMetamorphicQuartziteQuestion 4 of 205. What is weathering?Movement of rocks down a slopePhysical or chemical breakdown of rocks in-situFormation of new mineralsDeposition of sedimentsQuestion 5 of 206. What characterizes weathering as an in-situ process?It involves rapid movement of materialsLittle or no motion of materials occursIt requires wind as a transporting mediumIt only occurs in arid climatesQuestion 6 of 207. What are the two main types of weathering?Mechanical and biologicalPhysical and chemicalThermal and oxidativeHydrolysis and solutionQuestion 7 of 208. What role does water play in freeze-and-thaw weathering?It dissolves minerals completelyIt expands when frozen, widening cracksIt reacts chemically with oxygenIt reduces the rock’s volumeQuestion 8 of 209. Where is freeze-and-thaw weathering particularly effective?Tropical regionsHigh altitudes and mountainous regionsArid desertsCoastal areasQuestion 9 of 2010. Which rocks are most affected by freeze-and-thaw weathering?Igneous rocks like graniteSedimentary rocks like sandstoneMetamorphic rocks like quartziteHomogeneous rocksQuestion 10 of 2011. What is hydrolysis in chemical weathering?Dissolving minerals in waterReaction of water molecules with rock mineralsOxidation of iron in rocksFormation of carbonic acidQuestion 11 of 2012. Which process involves minerals dissolving in water?OxidationCarbonationSolutionShatteringQuestion 12 of 2013. What happens to limestone in the solution process?It oxidizes to form iron oxidesCalcium reacts with water to form carbonic acidIt becomes harderIt expands in volumeQuestion 13 of 2014. What elements commonly oxidize in rocks?Calcium and magnesiumIron and aluminumSodium and potassiumCarbon and nitrogenQuestion 14 of 2015. What color are iron oxides typically?YellowBlueRedGreenQuestion 15 of 2016. What process involves carbon dioxide reacting with rock minerals?HydrolysisCarbonationOxidationSolutionQuestion 16 of 2017. In which climate is carbonation most effective?AridHumidPolarDesertQuestion 17 of 2018. How does salt contribute to weathering?It dissolves completely in waterIt expands due to thermal propertiesIt reacts with oxygenIt reduces rock volumeQuestion 18 of 2019.
