Greenhouse effect:

Find the wrong one out

  • The name is derived from a green house which does not allow the heat to escape

  • It's a naturally occurring phenomenon

  • Responsible for maintaining average temperature 15℃

  • Greenhouse gases cannot absorb long wave or infrared radiation

If Green house effect had not there on Earth, the average temperature would be

  • -18℃

  • Can neither absorb nor emit

  • Both A and B

  • Found in Stratosphere

  • Acts as a shield to UV light

  • All of these

CFCs

Find the wrong one out.

  • Release Cl atoms in stratosphere

  • Used as refrigerant

  • Cl of CFCs degrade ozone releasing molecular oxygen

  • Cl atoms released out of CFCs are also used up during degradation of Ozone

Over Antarctica region, the ozone hole is

  • Due to no formation of Ozone

  • Due to high formation and low degradation of ozone

  • Due to low formation and high degradation of ozone

  • Due to no degradation of ozone

UV-B

  • Damages DNA and causes mutation

Soil Erosion and desertification least likely resulted in which of the following cases?

  • Over Cultivation

  • Unrestricted Grazing

  • Deforestation, Poor Irrigation Practices

  • Proper resource Utilization and Maintenance

Which of the following have come into wake of the green revolution?

(2) Water logging

  • Organic Farming

  • (4) Both 2 and 3

  • Soil salinity

  • 4

Find the wrong one out.

  • Due to increased urbanisation, desertification is the major problem.

  • Irrigation without proper drainage of water leads to waterlogging in the soil, affects the crops

  • Waterlogging affects the crops and hence the agriculture

  • Waterlogging cause salt to go downwards

According to an estimate, almost…….

Forests have been lost in the tropics compared to  only …… in  the temperate regions.

  • 20%, 10%

  • 60%, 12%

  • 40%, 1%

  • 30%, 2%

Which of the cultivation is responsible for deforestation?

  • Both A and B

  • Slash and Burn Agriculture

  • Jhum Cultivation

  • Cyclic Agriculture

Jhum cultivation causes deforestation in

  • North western states of India

  • South India

  • North Eastern state of India

  • North India

In Jhum cultivation, what is the probable fertiliser?

  • Cow dung

  • Ash

  • Compost

  • Cattle excreta

What is the difference between Jhum cultivation of earlier days and now a days?

  • Time gap for the recovery of land is increased

  • Time gap for the recovery of land is decreased

  • Ash is not used as fertilizer anymore.

  • No more forests are burn.

Which of the following is not an outcome of deforestation?

  • Enhanced CO2 concentration

  • Disturbed hydrologic cycles

  • Loss of Biodiversity, soil erosion

  • Soil salinity

Reforestation can

  • Occur naturally

  • Be speeded by planting trees with due consideration to biodiversity that earlier existed in that area

  • Occur during Jhum cultivation

  • All of these
