Carbon Plus Indicated by Arrows Natural Pur Anthropogenic Plus
The oceans absorb carbon through three processes that draw atmospheric carbon dioxide into the oceans: the physical
carbon pump, the biological carbon pump and the carbonate pump. In which scenario would a carbon sink be the
result of the physical carbon pump mechanism?
A

The movement of CO2 into and out of the ocean is fairly equal.

More more CO2 is diffusing out to the atmosphere than is diffusing into sea
surface water
More CO2 is diffusing into sea surface water than is diffusing from sea
surface water out to the atmosphere
More CO2 diffuses and dissolves in colder sea surface water and less CO2
diffuses and dissolves in warmer water

Environmental differences within ecosystems are generally caused by

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e.g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.
