, Test Bank for Chapter 1: The Science of Marine Biology (based on Marine Biology,
12th Edition by Castro & Huber), including:
25 Multiple Choice Questions (with answers & explanations)
15 True/False Questions (with answers & explanations)
5 Essay Questions (with answer guidelines)
Multiple Choice Questions (25)
1. What is the primary focus of marine biology?
a) The geology of ocean basins
b) The chemistry of seawater
c) The study of organisms living in the ocean
d) The physics of waves and tides
Answer: c
Explanation: Marine biology is the scientific study of organisms that live in saltwater
environments, from coastal estuaries to the deep sea.
2. Which of the following is an example of a marine biology research question?
a) How does plate tectonics shape the sea floor?
b) What causes the salinity of the ocean to vary?
c) How do coral reefs respond to rising water temperatures?
d) What determines the height of ocean waves?
, Answer: c
Explanation: Only option c focuses on a living organism (corals). The others are
geological, chemical, or physical oceanography.
3. The Challenger Expedition (1872–1876) is significant because it:
a) First proved the ocean was round
b) Discovered the first hydrothermal vents
c) Systematically sampled marine life from many ocean basins
d) Mapped the entire Pacific Ocean floor
Answer: c
Explanation: The HMS Challenger expedition was the first major global expedition
dedicated to studying ocean life, chemistry, and geology.
4. Who is often credited as the "Father of Marine Biology" for his work on marine
invertebrates and publishing The Ocean World?
a) Charles Darwin
b) Rachel Carson
c) Aristotle
d) Sir John Ross
Answer: c
Explanation: Aristotle described many marine species and is considered an early pioneer;
in modern contexts, the title is sometimes given to Edward Forbes or others, but Aristotle is
often cited historically.
