Factors Affecting Vegetation

Question 1ExpertLevel 59

If a question asks why vegetation changes, which will be the most scientific answer?

ABecause names changeBBecause only one cause works everywhereCBecause land, soil, climate and human impacts interactDBecause plants do not need water

Question 2ExpertLevel 59

Mangroves and cactus both show special adaptations, but how is their environmental pressure different?

AMangroves adapt to saline waterlogging and cactus to water shortageBBoth are linked only with snowfallCBoth are plants of extreme coldDBoth have the same environment

Question 3ExpertLevel 59

If an area has a large seasonal difference in day length, which plant aspect may be affected?

ATiming of flowering and growthBDepth of riverCState boundaryDWidth of road

Question 4ExpertLevel 59

In which condition can regularity of rainfall be more important than total amount for vegetation?

AWhen total rainfall is high, but there is a long dry interval between rainsBWhen total rainfall is extremely low, even if it is received regularlyCWhen the soil has very high water-holding capacityDWhen temperature remains favourable for plant growth throughout the year

Question 5ExpertLevel 59

If deforestation occurs on a steep slope, what will be the combined effect on vegetation and soil?

AErosion will increase and regrowth will become difficultBSoil will always become more fertileCDense forest will form immediatelyDNeed for water will end

Question 6ExpertLevel 59

If an area has very high moisture but also high salinity, which conclusion is correct?

AOnly salt-tolerant vegetation will surviveBEvery plant will grow fastCSalinity does not affect plantsDOnly cactus will be most suitable

Question 7ExpertLevel 59

Which option correctly states the combined role of temperature and rainfall?

AWarmth and moisture together can support dense growthBTemperature and rainfall have no relation with plantsCLow rainfall always creates mangrovesDExtreme cold and water shortage create evergreen forests

Question 8ExpertLevel 59

If vegetation is very sparse in an area, which combined reason is most likely?

ALow rainfall, poor soil and harsh temperature conditionsBHigh rainfall and deep fertile soilCContinuous moisture and favourable temperatureDComplete absence of deforestation

Question 9ExpertLevel 59

In which condition will water-loss reducing structures in plants be most necessary?

AIn a dry hot regionBIn a marshy coastal regionCIn a permanently waterlogged deltaDIn a high rainfall forest

Question 10ExpertLevel 59

Why does vegetation change step by step from lower to upper parts of high mountains?

ATemperature, moisture and soil conditions change with altitudeBAll plants become same upwardCAltitude has no relation with climateDMountains have no sunlight

Question 11ExpertLevel 59

If both natural vegetation and wildlife are declining, what does the basic relation show?

APressure on habitat and food chainBChange in languageCIncrease in river lengthDEnd of photoperiod

Question 12ExpertLevel 59

If an area has high rainfall but very little sunshine and low temperature, which conclusion is suitable?

AHigh rainfall will make tropical plants grow rapidlyBLack of light and heat can limit plant growthCRainfall alone will determine all the vegetation of that areaDLow temperature will allow only desert cacti to grow there

Question 13ExpertLevel 59

Which statement shows that vegetation is not controlled by a single factor?

ADespite equal rainfall, vegetation may change if soil and temperature differBOnly rainfall decides vegetationCSoil and temperature are irrelevantDHuman land use has no effect

Question 14ExpertLevel 59

If deforestation stops and soil conservation begins in an area, what is possible in the long term?

APossibility of natural vegetation regrowth can increaseBAll plants will end immediatelyCSoil erosion will always increaseDEffect of rainfall will end

Question 15ExpertLevel 59

In which condition is it necessary to read vegetation map and soil map together?

ATo understand the relationship between soil types and plant distributionBTo locate the capital of a regionCTo count railway routes in an areaDTo identify language regions in an area

Question 16ExpertLevel 59

If an area is moist but land is continuously marshy, what adaptation do plants need?

AAbility to tolerate marshy and oxygen-poor soilBTolerance of extreme drynessCTolerance of permanent snowDLife without light

Question 17ExpertLevel 59

In which condition will low rainfall and high temperature together put maximum pressure on plants?

AWhen transpiration is high and water availability is lowBWhen soil is deep and moistCWhen rainfall is regularDWhen waterlogging is permanent

Question 18ExpertLevel 59

Which option gives the most correct cause-effect relation?

ALow rainfall increases possibility of sparse thorny vegetationBSaline marsh creates alpine forestCAltitude always increases temperatureDDeforestation makes natural forests dense immediately

Question 19ExpertLevel 59

If climate is changing rapidly in an area, what long-term effect can occur on natural vegetation?

ASuitable species may increase and less tolerant species may declineBThere will be no effect on vegetationCAll plants will remain sameDNeed for soil will end

Question 20ExpertLevel 59

Why can study of local factors be more useful than national averages in vegetation conservation?

ABecause soil, slope, rainfall, and human pressure vary from place to placeBBecause national averages accurately represent all local environmental conditions of an areaCBecause conservation measures use only the country's total forest-cover percentageDBecause vegetation and human activities are identical everywhere within the same climatic region
