10 Questions
Match the following greenhouse gases with their characteristics:
CO2 = Efficient greenhouse gas, absorbs 60% IR radiation emitted by earth surface H2O = Source of clouds and precipitation O3 = Good in stratosphere and bad in troposphere GWP index = Metric indicating the contribution of a substance to global warming in comparison to CO2
Match the following greenhouse gases with their percentage distribution in the atmosphere:
CO2 = One third in the atmosphere after used up by plants and absorbed by ocean H2O = 4% in the atmosphere O3 = 10% in troposphere and 90% in stratosphere GWP index = An index based on radiative properties of greenhouse gases measuring the radiative forcing following a pulse emission of a unit mass
Match the following terms with their definitions:
Global Warming Potential (GWP) index = Introduced to put the contribution of all the non-CO2 GHGs gases to the climate change over the normalized CO2 scale Radiative forcing = Measure of the strength of the greenhouse effect Greenhouse gases = Substances that trap heat in the atmosphere Pulse emission = Emission of a unit mass of a given greenhouse gas in the present day atmosphere integrated over a chosen time horizon
Match the following terms with their sources:
CO2 = Burning of fossil fuels such as coal and oil H2O = N/A O3 = N/A GWP index = Intergovernmental Panel on Climate Change, 2013
Match the following statements with the correct greenhouse gas:
Efficient greenhouse gas, absorb 60% IR radiation emitted by earth surface. = CO2 Source of clouds and precipitation. = H2O Good in stratosphere and bad in troposphere. = O3 Metric indicating the contribution of a substance to global warming in comparison to CO2. = GWP index
What is the role of CO2 in the atmosphere and how is it sourced?
CO2 acts as an efficient greenhouse gas, absorbing 60% of IR radiation emitted by the Earth's surface. It is sourced from the burning of fossil fuels such as coal and oil.
Explain the significance of the Global Warming Potential (GWP) index and how it is calculated.
The GWP index measures the contribution of a substance to global warming in comparison to that of CO2. It is calculated based on the radiative forcing following a pulse emission of a unit mass of a given greenhouse gas in the present-day atmosphere integrated over a chosen time horizon, relative.
Describe the distribution and role of O3 in the atmosphere.
O3 is present in 10% in the troposphere and 90% in the stratosphere. It is beneficial in the stratosphere but harmful in the troposphere.
How does H2O contribute to the atmosphere, and what is its role in the formation of clouds and precipitation?
H2O comprises 4% of the atmosphere and serves as a source of clouds and precipitation.
Explain the fate of one-third of the CO2 in the atmosphere after it is used up by plants and absorbed by the ocean.
One-third of the CO2 remains in the atmosphere after being used up by plants and absorbed by the ocean.
Test your knowledge on the composition of the atmosphere and the importance of CO2 as an efficient greenhouse gas. Learn about its sources, including the burning of fossil fuels, and the impact of water vapor and ozone. Understand the role of these components in maintaining Earth's climate and weather systems.
