The bar graph above shows the release of carbon dioxide from fossil fuel burning in North America. Specifically, it points out that the amount of carbon dioxide released from fossil fuels burning greatly exceeds the amount of carbon dioxide that is taken up by forests, crops, and other ecosystems. Which three of the following technologies and activities help in reducing this imbalance?

i am going to guess that it is co2.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
