Which are the causes of climate change?
Emission of solar radiation.
Movement of the continents.
Changes in the gases that make up the atmosphere
Activity of the volcanoes.
Alterations in the marine currents in the Earth's orbit
Do greenhouse gases affect the weather?
Yes, greenhouse gases act as a mirror and that returns that radiation to the earth,
Yes, greenhouse gases form a film in the atmosphere from the outside it is completely transparent, it lets in solar radiation,
No, greenhouse gases have an effect on the climate.
Yes, greenhouse gases have an effect on the weather.
Which are the most important greenhouse gases?
Carbon dioxide.
Methane.
Nitrous oxide.
CFC
Ozone
Which can be considered greenhouse gases?
Water vapour.
Sulphurous oxide
CFC
Phosphorus oxide.
Which are the result of the greenhouse gases effect?
Hole in the ozone layer.
Nuclear energy.
Accumulation of heavy metals: thallium, chromium, lead, mercury in living beings.
Melting of the permafrost.
Holes in the ozone layer occurs in polar zones annually, they open and close.
True.
False.
Nuclear energy produces a large amount of electricity but emitting a large amount of greenhouse gases.
True.
False.
Heavy metals are enormously toxic, but they have absolutely nothing to do with the change in the climate.
True.
False.
Global warming is created by natural factors
True
False
How long does it take for carbon dioxide in the atmosphere to disperse?
50 years
10 years
1 year
100 years
Global warming is accelerated by the reduction of global snow and ice cover.
True
False
Beyond its consequences for climate change, why is it important that permafrost does not melt?
Gases such as hydrogen sulfide would be released into the atmosphere, producing acid rain in certain regions of the planet.
It would contribute to the rise in sea level, affecting Pacific islands whose population without resources would be forced to migrate.
Large amounts of land would be lost in natural settings, further reducing the space devoted to habitat conservation.
When melting due to the increase in temperatures, the organic matter that it houses inside would decompose, releasing large amounts of greenhouse gases and accelerating the process.
Positive feedback is a characteristic of climate change. This causes points of no return to be overcome as temperatures increase.
Which of these factors contribute to positive feedback?
The decrease of the albedo effect with the disappearance of glaciers and white surfaces in general.
The increase in the surface of the oceans.
Permafrost when melting and decomposing.
Increased rainfall.
Greenhouse gases can increase their warming potential over time
True.
False.
Greenhouse Gas (GHG) with a global warming potential greater than carbon dioxide (21 to 30 times higher)
Oxygen.
Nitrogen.
Methane (CH4)
Carbon dioxide (CO2)
The impacts of climate change are:
(Select all applicable ones)
Increase in temperature.
Melting of poles and glaciers.
Sea level rise.
Increase in hurricane intensity.
It is the Greenhouse Gas (GHG) that is generated in greater quantities.
Oxygen.
Nitrogen
Methane (CH4)
Carbon dioxide (CO2)
A clear correlation has been found between the concentration of CO2 in the atmosphere and:
Albedo.
Solar power.
Global temperature.
Radiative forcing.
Which of the following statements is true?
A soil covered with vegetation reflects more radiation than snow.
A white surface absorbs all the radiation that reaches it.
A black surface reflects all the radiation that reaches it.
Albedo depends on the surface reached by the luminous rays.
The melting of glaciers is evidence of climate change. Which of the following relationships between melting glaciers and albedo is correct?
The albedo will not change, because the ice continues to reflect the light that reaches it.
Albedo increases because glaciers release methane and carbon dioxide when melting.
The albedo increases because the ice melts and mixes with sea water.
The albedo decreases because the ice melts with sea water when melts.
What is the main function of thermohaline?
Regulates the planet's weather and exchanges clouds
It's very fast and serves to navigate
Regulates the planet's climate and exchanges bodies of water
Thermohaline circulation in the seas and oceans works thanks to the_________________________.
Temperature and salinity.
Distance between bodies of water.
Amount of fish.
Temperature and carbon dioxide.
Which of the following accounts for the largest portion of carbon footprint when it comes to food?
Processing
Transportation
Cooking
Waste disposal
Does deforestation contribute to global warming?
No, trees are not so important.
A veces porque solo la tala de árboles de arce contribuye al calentamiento global
No, deforestation adds methane to the atmosphere, which causes the Earth to cool down.
Yes; Fewer trees means less CO2 converted into oxygen.
Excessive indiscriminate felling of trees causes:
Soil erosions.
Excessive animal grazing.
Excessive production of trees.
Neither
