Which of the following describes factors that may contribute to annual variations in phytoplankton population in the Siberian Seas? Use what you know of the properties of ocean water, as well as the Plankton Distribution graph below.
How does the temperature of ocean water change in the thermocline?
Coral reefs require very specific conditions to survive, and climate change is having an impact on their habitats. Determine whether each of the following statements is true or false.
Like other plants, coral reefs thrive with an increasing amount of carbon dioxide in the atmosphere.
The burning of fossil fuels is responsible for increasing the amount of carbonic acid in ocean water, which harms coral reefs.
The increase in the greenhouse effect caused by human activity is causing a change in water temperature that leads to bleaching.
The amount of carbon dioxide in the atmosphere can be tracked by examining the thickness of corallites.
True
False
The properties of ocean water vary greatly with latitude, partly because of differences in water temperature. Compare Regions A and B in the figure by connecting each description of the sea surface to the appropriate area.
Has a higher temperature
Has a higher density
Contains a higher amount of dissolved solids
Receives a greater amount of solar radiation
Contains a higher amount of dissolved oxygen
Region A
Region B
