Ocean chemistry and carbon cycle

What is the carbon cycle?

• the series of processes by which carbon compounds are interconverted in the environment

• When fossil fuels are burned

• Photosynthesis

• The process of carbon moving between the land and air, causing climate change.

Which two systems are in "balance" with each other.

• Volcanism and ocean acidification

• Photosynthesis and respiration

• Plankton and crabs

• The carbon cycle and the nitrogen cycle

What is not an issue involved in the burning of fossil fuels.

• Releases previously trapped carbon into the atmosphere.

• Causes air pollution

• Contributes to acid rain

• Reduces ocean salinity.

What is a greenhouse gas?

• A gas that can absorb UV light

• A gas that can absorb infrared light

• A gas that can absorb visible light

• A gas found in a greenhouse

Which of the following is NOT a greenhouse gas?

• Ozone

• Chlorofluorocarbons

• Nitrogen

• Methane

What is the greenhouse effect?

• Climate change

• The sole source of heat for Earth

• The process in which heat is trapped in the atmosphere.

• A natural process that traps air in the atmosphere.

The pH of an acidic solution will be...

• Lower then 7

• Above 7

• Exactly 7

Thermohaline circulation is also known as...

• The undersea escalator

• The deep current

• The fishy highway

• The Great Ocean Conveyor Belt

What moves surface currents?

• Gravity

• High salinity

• Wind

• The moon

What causes deepwater formation (surface currents becoming deep currents)

• An increase in density due to cooling and increasing salinity.

• An increase in density due to cooling and decreasing salinity.

• A decrease in density due to cooling and increasing salinity.

• A decrease in density due to cooling and decreasing salinity.
