Oceanography Final Study Q's Part 1

The Challenger expedition made collections of marine organisms:

• Around the world

• In the Pacific Ocean only

• In the Atlantic Ocean only

• In the Mediterranean Sea only

Which of the following was develop due to technological advances mad during World War II

• Scuba

• Research Vessels

• Marine Laboratories

• Sonar

The Scientific Method can best be described as:

• Undertaking experiments in laboratories

• Using Induction & Deduction

• Collecting Data in the field

• Following a set of procedures to learn about our world

The Factors that Might affect observations & can be manipulated are called:

• Controls

• Variables

• Experiments

• Inductive Observations

A control can best be defined as:

• A variable that is kept constant in an experiment

• An experiment where the final results are known ahead of time

• A hypothesis that regulates the results of an experiment

• A variable that changes during the course of an experiment

A marine biologist observes that mako sharks, sardines, and salmon leap out of water. An example of induction from these observations is:

• Only some fishes can leap out of the water

• All fishes leap out of water

• Fishes leap out of water to escape predators

• Leaping out of water is often used in feeding

An experiment can best be described as:

• A set of observations that become a hypothesis

• Obtaining data from the field

• an artificially created situation to test a hypothesis

• Controlling a a particular factor in the field

Scientific knowledge is ultimately traced to:

• Hypotheses

• Inductions

• Deductions

• Observations

This is thought to have originated in the sea

• Water

• Salt

• Life

• The Earth's crust

To study marine life at depth, scientist take advantage of all these tools except:

• Satellites

• Remotely operated vehicles

• Submarines

• Scuba
