Plastic Pollution Review

What are plastics made from?

• Plastics are made from metal

• Plastics are made from petrochemicals

• Plastics are made from wood

• Plastics are made from glass

Where do most of the plastic waste end up?

• Most of the plastic waste is recycled

• Most of the plastic waste goes to landfills

• Most of the plastic waste is used to build things

• Most of the plastic waste is thrown into the ocean

How does plastic pollution harm wildlife?

• Plastic pollution harms wildlife by making them sick  

• Plastic pollution harms wildlife by causing them to lose their homes  

• Plastic pollution harms wildlife by disrupting their hormones 

   

• Plastic pollution harms wildlife by making them hungry 

What is the primary reason why plastics are named as such?

• Because they are made from oil

• Because they come from natural products like corn

• Because of their ability to be shaped and molded

• Because of their absorb chemicals

Why are plastics dangerous to wildlife?

• They break down quickly and harm organisms

• They absorb excess sunlight and overheat ecosystems

• They absorb harmful chemicals and are often eaten by wildlife

• They are too large and obstruct habitats

How do oceanic gyres contribute to the accumulation of plastic trash?

• They create currents that transport plastics to shore

• They trap plastic waste within large clumps called "garbage patches"

• They absorb plastic waste and disperse it across the ocean

• They collect plastic from coastal litter and circulate it in rotating currents

What method did scientists use to estimate the amount of plastic waste in the ocean?

• They directly measured the entire ocean floor for plastic waste

• They used computer models and sampled a fraction of each oceanic gyre

• They relied solely on eyewitness accounts of plastic pollution

• They estimated plastic waste based on the weight of plastics produced annually.

What did scientists discover about the distribution of plastic waste in the oceans?

• The majority of plastic waste is found on the ocean floor

• The smallest plastic particles are the most abundant

• Plastic waste is evenly distributed across all oceanic gyres

• The North Pacific gyre had the highest concentration of plastic waste

Why do scientists believe their estimate of ocean plastic waste might be underestimated?

• Because they overestimated the weight of large plastic particles

• Because they only measured the surface of the water

• Because they found fewer tiny particles than predicted

• Because they did not consider the impact on wildlife consumption

What did scientists conclude about the fate of plastic waste in the oceans?

• It primarily sinks to the ocean floor where it remains

• It is broken down into smaller particles by ocean currents

• It eventually evaporates due to exposure to sunlight

• Its final resting place and the fate of the smallest particles remain uncertain
