NGSS.MS-LS2-4

Part of any ocean that lies beyond the continental shelf.

• open ocean

• coastal wetland

• benthic zone

• estuary

• brackish water

Rising levels of acidity in ocean waters, occurring because the oceans absorb at least 25% of the carbon dioxide emitted into the atmosphere by human activities, especially the burning of carbon-containing fossil fuels. The carbon dioxide reacts with ocean water to form a weak acid that can endanger entire ecosystems.

• ocean acidification

• coastal runoff

• ocean plastic pollution

• acid rain

• brackish water
