period?
O
A. Atlantic Ocean, Indian Ocean, Pacific Ocean
O
B. Volume, density, temperature
O
C. Sea level, Pacific Ocean, 1955 to 1975
O
D. Wind speed, pH, salinity

Answer 1

Answer:

C. is the correct answer.  Sea level, Pacific Ocean, 1955 to 1975.  

Explanation:

Letter C is the correct link because you are looking for the change in the height of an ocean over a 20 year period of time.

The reason for this is because A only has names of oceans, therefore wouldn't help you find the changes in height or the number of years.  B has volume, density, and temperature, but you are not trying to find the mass of the ocean.  Finally, D has the wind speed, pH, and salinity, and you are not looking for any of those.
