ANSWERS COMPLETE PREPARATION FILE
●● What are the similarities and differences between marine biology and
oceanography?
Answer: Marine Biology is the study of the organisms that inhabit the
sea and oceanography is the study of the non-living aspects of the ocean
(tides, currents, waves, etc.)
●● Why should we study marine biology?
Answer: The ocean: provides clues about early life on Earth, many
products come from the sea (food, medicines derived from marine
species), marine organisms produce oxygen for all kinds of organisms
including humans, marine ecosystems provide recreation and supports
tourism worldwide, and the Earth's oceans help regulate climate
●● Tools used to observe the ocean
Answer: sonar, remotely operated vehicles (ROV's), scuba, remote
sensing (satellites)
●● SONAR
Answer: a system of echolocation used to map seafloor depths and
formations
, ●● ROVs
Answer: remotely operated vehicles that allow for direct exploration of
the deep ocean when scuba can't
●● Steps of the Scientific Method
Answer: observation, research, hypothesis, experiment, 2nd observation,
more research, 2nd hypothesis, 2nd experiment, conclusion, share results
●● hypothesis
Answer: a prediction of what you believe will occur that can be
disproven by the availability of evidence
●● scientific theory
Answer: a hypothesis that has been tested repetitively over time by many
people and has not been disproven
●● "every day" theory
Answer: a hunch or a suspicion of what you think to be true
●● ocean acidification
Answer: the decrease of the pH of the ocean
