Answer: (b) - Which one of the following causes global warming?
a) Carbon dioxide
b) Oxygen
c) Nitrogen
d) Hydrogen
Answer: a
Explanation: About 75% of the solar energy reaching the earth is absorbed by the earth’s surface, and the rest radiates back to the atmosphere. Some of the heat is trapped by greenhouse gases such as carbon dioxide, which is released by various human activities. - How many percent of carbon dioxide has increased in the atmosphere since pre-industrial times?
a) About 10%
b) About 20%
c) About 30%
d) About 40%
Answer: c
Explanation: The carbon dioxide in the atmosphere has increased by about 30% since pre-industrial times, causing more heat to be trapped in the lower atmosphere. Human activities, industrialization, and population growth are the main reasons. - What is the full form of UNFCC with respect to the global warming convention?
a) United Nations Framework Convention on Climate Change
b) United Nations Federation Convention on Climate Change
c) United Nations Framework Center on Climate Change
d) United Nations Federation Center on Climate Change
Answer: a
Explanation: In order to control the continuous increase in the carbon dioxide level, many countries have signed a convention to reduce greenhouse gases under the United Nations Framework Convention on Climate Change (UNFCC). - Who measures the global warming rate?
a) Astrologers
b) Physicist
c) Philosopher
d) Climatologist
Answer: d
Explanation: Global warming is usually calculated by climatologists. Global warming is accelerating faster than that calculated by climatologists. It was predicted in 1995 that in the 21st century, there would be a rise in temperature by 3.5 to 10 degrees Celsius. - Which one of the following results takes place due to global warming?
a) Maintaining steady temperature
b) Changes in the rainfall
c) Pleasant environment
d) Causing less pollution
Answer: b
Explanation: Global warming leads to changes in temperature and also changes the amount of rainfall, causing various problems. These fluctuations in rainfall can lead to either floods or droughts. - Human activities cause global warming.
a) True
b) False
Answer: a
Explanation: Human activities during the last few decades of industrialization and population growth have seriously polluted the atmosphere to the extent that it has begun to seriously affect vegetation and organisms in the environment. - Which one of the following causes global warming?
a) Radiative forcing
b) Earth gravitation force
c) Oxygen
d) Centripetal force
Answer: a
Explanation: Radiative forcing is a measure of the influence of a given climatic factor that has an amount of downward-directed radiant energy. Global warming is caused by a change in the fraction of the radiation reaching the surface of the earth. - How has human activity influenced global warming?
a) By planting more trees
b) By causing changes in gravitational force
c) By changing the radiative balance governing the Earth
d) By protecting the environment
Answer: c
Explanation: Human activity has influenced global surface temperature by changing the radiative balance governing the Earth on various timescales. The introduction of greenhouse gases to the environment results in greater damage to the environment. - Which one of the following is the anthropogenic radiative forcing of climate?
a) Aerosols
b) Cement
c) Paper
d) Glass
Answer: a
Explanation: Aerosols represent an important anthropogenic radiative forcing of climate. Collectively, aerosols block, reflect, and absorb a portion of incoming solar radiation. This also creates negative radiative forcing. - Which one of the following land uses causes global warming?
a) Increase in the fertility of soil
b) Surface reflectance
c) Forestation
d) Adopting organic farming
Answer: b
Explanation: The most direct way in which changes in land use can influence global warming is surface reflectance or Earth albedo. For example, surface reflectance is affected by the replacement of forests with cropland. - Changes in the composition of the atmosphere is an example of:
a) Internal forcing
b) External forcing
c) Mid forcing
d) Gravitational forcing
Answer: b
Explanation: The climate system generates random changes in global temperature for years to decades at a time, but long-term changes emanate only from external forcing. An increase in the concentration of greenhouse gases is an example of external forcing, including changes in the composition of the atmosphere. - What is the main reason for the melting of ice sheets?
a) Increase in the oxygen content
b) Global warming
c) Decrease in carbon dioxide content
d) Noise pollution
Answer: b
Explanation: Global warming is affecting various places around the world. It has accelerated the melting of ice sheets, permafrost, and glaciers, thereby causing a rise in the average sea levels to a greater extent continuously. - Which one of the following is the effect of global warming?
a) Maintaining sea level
b) Proper rainfall
c) Desertification
d) Afforestation
Answer: c
Explanation: Desertification is one of the effects of global warming. It causes water shortages and an intense amount of distress in the dry regions, which are degraded into deserts. This process is called desertification. - Soot only warms Earth’s climate system.
a) True
b) False
Answer: b
Explanation: Soot can either cool or warm Earth’s climate system, depending on whether it is airborne or deposited. Atmospheric soot directly absorbs solar radiation, which heats the atmosphere and cools the surface.
