Q. No.The accidental leakage of nuclear energy occurred in
(1) Three mile Island
(2) Chernobyl Incident
(3) Bangalore
(4) Both A and B
(1) Three mile Island
(2) Chernobyl Incident
(3) Bangalore
(4) Both A and B
Nuclear waste
Find the wrong one out.
(1) Lethal at high doses
(2) Causes cancer at low doses
(3) Should be stored in the shielded containers buried within rocks about 100m deep
(4) An extremely potent pollutant
Greenhouse effect:
Find the wrong one out
(1) The name is derived from a green house which does not allow the heat to escape
(2) It's a naturally occurring phenomenon
(3) Responsible for maintaining average temperature 15℃
(4) Greenhouse gases cannot absorb long wave or infrared radiation
If Green house effect had not there on Earth, the average temperature would be
(1) -18℃
(2) 10℃
(3) 0℃
(4) -2℃
Greenhouse gases
(1) Absorb long wave or infrared radiation from the Earth
(2) Emit the long wave or infrared radiation towards the Earth
(3) Can neither absorb nor emit
(4) Both A and B
Which of the following is wrong?
A.Emission of infrared by Earth's Surface
B.Clouds and gases reflect one fourth of incoming solar radiation
C. Carbon dioxide and methane absorb a major fraction of infrared radiation emitted by Earth
D. During the past century, the temperature of Earth has increased by 0.6℃, most of it during the last five decades
What does El Nino effect mean?
(1) Rise in temperature due to global warming going to result in odd climatic changes
(2) Rise in use of chemical fertiliser going to cause metabolic disorder
(3) Rise in use of CFCs going to cause ozone depletion
(4) Rise in use of Plastic going to destroy sea animals
Relative contribution of various greenhouse gases to total global warming will not be
(1) Carbon dioxide-60%
(2) Methane-20%
(3) CFCs-14%
(4) N2O-12%
Ozone
(1) Ozone hole is the area above Antarctica
(2) Ozone layer is the thinnest above Antartica
(3) Ozone thickness is measured in Dobson unit
(4) All of these
Ozone hole over Antarctica develops each year between
(1) Early October and Late December
(2) Late August and Early October
(3) Early August and Late October
(4) Late October and Early December
