Knowledge and Skills Statement

Earth and space. The student understands how human activity can impact the hydrosphere.

The ocean influences climate by storing and moving heat from warmer regions to cooler regions. The oceans act as an air filter processing human-caused carbon dioxide, which is critical to the carbon cycle. The ocean stores 50 times more carbon than the atmosphere.

The ocean and coastal ecosystems provide nearly a million jobs in the United States through fishing, recreation, and tourism. The ocean provides a steady food source for people around the globe and provides transportation between land masses.
