What Active volcanoes are added to the early Earths atmosphere?
There are smallamount of volcanoes. They emit so2 and co2 gases.
Is the greatest source of air pollution volcanic eruptions or burning fossil fuels?
Definitely the burning of fossil fuels. Volcanoes emit around 100,000,000 tons of CO2 a year. Man-made emissions of CO2 comes to about 10,000,000,000 tons of CO2 per year. So volcanoes emit around 1/100th of CO2 that we do.
Where does the volcanoes emit come from?
Volcanoes can emit lava,rocks,ash,fragments and molten rock.
What types of gas do volcanoes emit?
oxygen
What gives off CO2 in everyday life?
Animals emit CO2 when they exhale.
Does the Amazon emit or absorb co2?
It absorbs Co2 through the process of Photosythisis.
Does plants release co2?
No. Plants emit their own CO2 through respiration.
Why do you think are metallic deposit abundant in places where there are trenches or volcanoes?
because of the minerals emit by the volcanoes
Do all volcanoes erupt lava?
Lava emissions are found with all active volcanoes, although some volcano emit more lave than others.
Do cars emit co2?
Yes, infact vehicles are considered to be the main contributor to the Co2 in the atmosphere
How does the amount of carbon dioxide that is emitted by volcanoes compare with the amount of carbon dioxide that is added to the atmosphere as a result of human activities?
On average less than 1%. It is estimated that volcanoes emit on average 200 million tonnes of CO2 a year. This includes all volcanoes, hot springs and and undersea hydrothermal vents. Humans emit 26 billion tonnes (2003) a year by burning fossil fuels. The gas burnt onsite at oil wells in gas flares accounts for more CO2 emissions than all volcanoes put together.
How much CO2 does Australia emit?
1% of the worldds emissions
