Unlike the other processes, driving a hybrid vehicle does not actively remove carbon from the atmosphere. Trees and native flora that are planted absorb atmospheric carbon, fossilization removes carbon from the active recycling of carbon, and carbon dioxide readily dissolves in seawater. Driving a hybrid car releases less carbon into the atmosphere than driving one powered solely by fossil fuels; however, driving a hybrid vehicle does not actively remove carbon from the atmosphere. Hybrid vehicles produce fewer carbon emissions, but they do not take carbon out of the atmosphere.

The El Niño phase of ENSO is associated with warmer surface temperatures in the eastern Pacific and higher rainfall in the central Pacific. Storms and hurricanes are more frequent in the central Pacific. There is a weaker upwelling of nutrient-rich water off the coast of South America during this phase.

The correct response is Pacific Ocean. ENSO occurs specifically in the Pacific Ocean, thus its impacts will most strongly impact countries bordering the Pacific.

The correct response is La Nina. The La Nina has low air pressure and cooling, while El Nino contains high air pressure and warming. Madden-Julian oscillation and Coriolis effect do not make sense as answer choices. 

97% of the Earth's water is saltwater and unusable for drinking or farming. of the 3% that is actually freshwater, 2% is frozen in glaciers, leaving humans with 1% of all water on earth to use for farming. 

Shade provided by the riparian zone is crucial to stream temperature regulation.

The riparian zone is the edge of a river or stream, therefore it has high biodiversity due to edge effects. Biofilters in the riparian zone protect the aquatic environment it surrounds. Also, because the riparian zone spans distances of an aquatic environment's edge, it serves as a corridor for wildlife.

The correct response was 10,000 years ago. The Great Lakes formed during glacial recession of the most recent glaciation. This most recent glacial recession occurred between 10-15 thousands years ago. As the glaciers receded northward across North America, melting glacial waters drained and formed what is now known as the Great Lakes. 

Lakes, streams, rivers and ground water account for about a half a percent of the fresh water found on Earth. 

The correct response is 0.02%. The rest of the water resources are either too salty, too deep, or too cold in frozen icecaps. 

Desalinization involves heating seawater to a boil, resulting in pure, distilled water vapor with no impurities. While any ferally-funded project is subject to environmental assesments, the major roadblock for these facilities is the heat energy required to distill the seawater.
