Green house effect is increasing due to
-
Increasing $CO _2$ concentration
-
Increasing $SO _2$ concentration
-
Increasing concentration of chlorofluorocarbons
-
Hole in ozone layer
The higher concentration of carbon dioxide in the atmosphere is likely to increase the temperature as carbon dioxide permits the short wavelength visible radiations to pass through it but traps the longer wavelength infrared radiation reflected by earth's surface. This is called the greenhouse effect and it results in the overall increase in the global temperature, called global warming. Carbon dioxide contributes to the 81% of the greenhouse gases because it tends to persist in the atmosphere.

Ozone layer effect

Solar effect
-
Radioactive effect
-
Green house effect
The greenhouse effect can be defined as the trapping of radiations of the sun by the tropospheric gases and preventing these radiations from reflecting back to space. The tropospheric gases involved are atmospheric dust, Ozone, Carbon dioxide and water vapour. These gases are responsible for causing global warming.
Green house effect is due to the accumulation of
-
$O _3$ and depletion of $CO _2$
-
$O _3$ and $CO _2$
-
$CO _2$ and depletion of $O _3$
-
Green plants
Which one of the following is mismatched?
-
Fossil fuel burning- Release of $CO _2$
-
Nuclear power- Radioactive wastes
-
Solar energy- Green house effect
-
Biomass burning- Release of $CO _2$
Solar power is the conversion of energy from sunlight into electricity. It is a clean form of energy with zero emission of harmful gases. It decreases dependency on the burning of fossil fuels which emits greenhouse gases which contribute to the warming of the earth's surface in excess.
Green house effect is due to
-
X-rays
-
UV rays
-
Green rays
-
Infra-red rays
The greenhouse effect is the trapping of the infra-red rays that are reflected by the earth's surface by the atmospheric gases. These gases like carbon dioxide, methane, CFCs, sulphur tetrafluoride etc. are named as greenhouse gases. As a result, these rays are not reflected back to space and increase the overall temperature of the earth, called global warming. The burning of fossil fuels and deforestation are the main anthropogenic causes of the accumulation of greenhouse gases.
Checking of reradiating heat by atmospheric dust, $O _3, CO _2$ and water vapours is
-
Ozone layer effect
-
Radioactive effect
-
Greenhouse effect

Solar effect
The greenhouse effect can be defined as the capture and re-radiation of the infre-red radiations by the tropospheric gases like ozone, carbon dioxide, water vapours and dust. This lead to the increase in the temperature of the atmosphere, and as a result the over all temperature of the earth increases, causing global warming.
A. Ozone layer effect is the absorption of UV rays.
B. Radioactive effect is the release of the radiations by radioactive substances.
C. The greenhouse effect can be defined as the capture and re-radiation of the infre-red radiations by the tropospheric gases like ozone, carbon dioxide, water vapours and dust.
D. Solar effect is the massive release of solar flares.
Hence, the correct answer is 'Greenhouse effect'.
One green house gas contributes $14\%$ to total global warming and another contributes $6\%$. These are respectively identified as
-
$NO _2$ and $CO _2$
-
CFC and $N _2O$
-
Methane and $CO _2$
-
Methane and CFCs
-
CFCs and $CO _2$
Cattle ranches cause acute green house effect because of
-
Methanogenic bacteria in rumen
-
Mechanised milking practices
-
Decomposition of organic remains in faeces
-
Decomposition of left over fodder
Climate of the world is threatened by
-
Increasing amount of atmospheric $CO _2$
-
Decreasing amount of atmospheric $CO _2$
-
Increasing concentration of atmospheric $O _2$
-
Decreasing amount of atmospheric $O _2$
Carbon dioxide is a naturally occurring gas. It shows greenhouse effect by absorbing the the long-wavelength infra-red radiations coming from the earth's surface and preventing from leaving the atmosphere. This effect is responsible for maintaining the ambient temperature on the earth. However, due to increase in combustion of fossil fuels like petroleum and coal and excessive deforestation, the amount of carbon dioxide has increased over the past years and this has adversely affected the global temperature by raiding it. This is called global warming and is responsible for climate change.
