Biomass power is a renewable energy source derived from plant and animal products. Which of these is a benefit of using biomass for power compared to nonrenewable resources? Options: Biomass power increases the amount of oxygen in the air, Biomass power reduces the emission of greenhouse gasses, Biomass power increases the clearing of forests and grasslands for energy crops, Biomass power reduces organic waste in landfills and waste-treatment facilities.

Back

Biomass power reduces organic waste in landfills and waste-treatment facilities.

Front

Why would it be easier to contain an oil spill that occurs on land?

Back

Oil spills at sea are more likely to spread with water currents than oil spills on land are through erosion and deposition.

Front

Classify sea salt and describe its costs and benefits.

Back

Sea salt is a nonrenewable resource that has a wide variety of uses, but harvesting from the ocean can disrupt coastal ecosystems.

What is not an environmental cost of degrading the ocean’s resources as evidenced through the Great Pacific Garbage Patch? Options: Sea turtles confuse the plastic bags for jellyfish, The plastic accelerates the rate of bacterial decomposition, The plankton population will decrease, and fish will have less food available, The trash collects on ocean surface, blocking sunlight and affecting photosynthesis.

Back

The plastic accelerates the rate of bacterial decomposition.
