• Hydrochloric acid

• Sulfuric acid

• Nitric acid

Which best explains why the Ocean is called a carbon sink?

• The ocean has no impact on atmospheric carbon levels.
• The ocean absorbs and stores carbon dioxide from the atmosphere.
• The ocean releases carbon dioxide into the atmosphere.
• The ocean is primarily made of salt water, not carbon.

The best definition for bioclastic rocks:

• Bioclastic rocks are sedimentary rocks composed of fragments of biological origin.
• Bioclastic rocks are igneous rocks formed from cooling magma.
• Bioclastic rocks are exclusively composed of mineral fragments.
• Bioclastic rocks are formed from volcanic activity.

Which best describes the relationship between levels of carbon dioxide in the atmosphere and ocean acidification:

• Higher levels of carbon dioxide in the atmosphere lead to increased ocean acidification.
• Higher levels of carbon dioxide decrease ocean acidity.
• Ocean acidification is unrelated to atmospheric carbon dioxide levels.
• Increased ocean temperatures reduce ocean acidification.

Identify two problems associated with increased ocean acidification:

• Enhanced oxygen levels in ocean waters.
• Harm to marine organisms that rely on calcium carbonate for shells and skeletons.

• Decline in coral reef health and growth.

• Increased fish populations in coastal areas.
• Reduction of plastic pollution in the ocean.

NGSS.HS-LS2-7

Identify two problems associated with the Great Pacific Garbage Patch:

• Increase in ocean temperature due to climate change.
• Harm to marine life due to entanglement. Impacting the food chains.

• Improvement of water quality in the Pacific Ocean.
• Enhanced fishing opportunities in the affected areas.
• Marine life consuming plastics and then humans consuming marine life

Identify one (1) way in which humans can fix the Giant Pacific Garbage Patch issue:

• Ignore the problem and hope it goes away.
• Deploy specialized cleanup vessels to collect plastic debris.
• Promote the use of single-use plastics.
• Encourage ocean dumping of waste materials.
• Increase plastic production to meet demand.

Identify the best definition of overfishing:

• The depletion of fish stocks from removing fish faster than they can reproduce.

• The practice of fishing without any regulations.
• The increase of fish stocks due to conservation efforts.
• The sustainable management of fish populations.
