MCQ Chapter 2 Geography Class 11 Maharashtra Board Weathering and Mass Wasting 1. How does water contribute to mass wasting?It reduces material weightIt increases material weight and reduces frictionIt hardens the soilIt prevents slidingQuestion 1 of 202. Which rocks are more susceptible to mass wasting?Homogeneous rocksRocks with joints or clay mineralsHard metamorphic rocksCompact sedimentary rocksQuestion 2 of 203. What is a creep in mass wasting?Rapid fall of rocksVery slow movement over yearsSudden slide of soilFast flow of water and rockQuestion 3 of 204. What characterizes a slide in mass wasting?Free fall of rocksMovement as a single mass along a slippery zoneSlow creep of soilMixture of water and rockQuestion 4 of 205. What type of mass wasting involves a mixture of water, rock, and weathered material?CreepSlideFlowFallQuestion 5 of 206. Where does solifluction typically occur?Desert regionsPeriglacial or alpine regionsTropical regionsCoastal areasQuestion 6 of 207. What prevents water from percolating in solifluction?VegetationPermafrostSandGraniteQuestion 7 of 208. Why are deforested areas prone to mass wasting?They have strong root systemsSoil becomes weak without vegetationThey have less rainfallThey are flatQuestion 8 of 209. What type of mass wasting is rapid and occurs in rocky areas?CreepRock fallSlideSolifluctionQuestion 9 of 2010. Where does earth flow typically occur?Arid regionsHillsides in humid regionsFlat plainsCoastal cliffsQuestion 10 of 2011. What factor increases the likelihood of slides in humid climates?Lack of waterHigh temperaturesSaturated soilStrong vegetationQuestion 11 of 2012. What role does clay play in mass wasting?It hardens the slopeIt absorbs water and prevents percolationIt reduces slope weightIt increases frictionQuestion 12 of 2013. What human activity can add weight to slopes, causing mass wasting?DeforestationConstruction activitiesIrrigationFishingQuestion 13 of 2014. What is the slowest type of mass wasting?SlideFlowCreepFallQuestion 14 of 2015. What type of weathering does stone quarrying cause?ChemicalBiologicalAnthropogenicThermalQuestion 15 of 2016. Which factor does not directly cause chemical weathering but speeds it up?WaterHeatOxygenCarbon dioxideQuestion 16 of 2017. What is the result of weathering in terms of landforms?Formation of mountainsCreation of soils and landformsHardening of rocksReduction of slopesQuestion 17 of 2018. What concentrates iron or aluminum in high rainfall regions?OxidationLeachingCarbonationHydrolysisQuestion 18 of 2019. What caused the mudslide in Malin village in 2014?EarthquakeHeavy rainfall and slopeDeforestation aloneVolcanic activityQuestion 19 of 2020.
