| What are the names of Alberta's Oil Sands? | Athabasca Oil Sands Cold Lake Oil Sands Peace River Oil Sands |
| What are some impacts to the environment that Oil Sands hold? | Large Areas of forests are cleared. H2S is increase in areas of extraction. Large growth in GHG emissions. |
| What are some Causes of Oil Spills? | All oil is transported away from the site to anywhere around the world, that gives it lots of oportunity for an accident or spillage. "Super tankers" through open waters, smaller tankers through in land waters, even through terrestrial and marine pipes.. some is also even intentialy spilled as war or terrorist attacks. |

| What are some Chemical/Biological Methods of clean up? | Dispersants, chemicals contain solvents to break up oil into small droplets. Gelling agents, that react with oil to create a more rubbery oil clump that is easier to collect. Biological agents like adding bacteria to break up oil. |
| What effects do oil spills have on Wildlife? | Seabirds that are effected can't fly, lose insulation and buyancy which means they will either freeze to death or drown, and are too heavy so they can't fly. As all same effects on other marine mammals. |
