SDSU Oceans 100 Practical 1 UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Latitude - CORRECT ANSWER - Distance north or south of the equator
Longitude - CORRECT ANSWER - Distance east or west of the prime meridian,
measured in degrees
Prime Meridian - CORRECT ANSWER - 0 degrees longitude
England
International Date Line - CORRECT ANSWER - the imaginary line that separates two
consecutive calendar days
sits on 180 degrees longitude
great circle - CORRECT ANSWER - If a plane intersects the exact center of a sphere, then
a "great circle" is produced
-"great" means that the circle will be the largest possible, essentially cutting the sphere in half.
small circle - CORRECT ANSWER - One whose plane does not pass through the center of
the sphere, occurs on the surface
nautical mile - CORRECT ANSWER - one "arc minute" of distance along any great circle
at sea level over the Earth's surface.
=1.852 kilometers
arc minute - CORRECT ANSWER - 1/60th of a degree
, Universal Coordinated Time (UTC) - CORRECT ANSWER - -time at the prime meridian
-1600 o'clock
North Star (Polaris) - CORRECT ANSWER - This star has been used through historical
time for navigation and orienting to the north
-is aligned above the Earth's axis of rotation at the north pole
sextant - CORRECT ANSWER - a device for a precise measurement of the angle from a
celestial (in the sky) body and the Earth's horizon.
chronometer - CORRECT ANSWER - instrument that is accurate and precise time-
keeping under the extreme conditions of open ocean sailing.
5 oceans - CORRECT ANSWER - Pacific, Atlantic, Indian, Artic and Antarctic (Southern)
continental drift - CORRECT ANSWER - The hypothesis that states that the continents
once formed a single landmass, broke up, and drifted to their present locations
plate tectonics - CORRECT ANSWER - The theory that pieces of Earth's lithosphere are
in constant motion, driven by convection currents in the mantle.
seafloor spreading - CORRECT ANSWER - The process that creates new sea floor as
plates move away from each other at the mid-ocean ridges
Hypothesis - CORRECT ANSWER - a testable idea that could potentially be false
Theory - CORRECT ANSWER - structure of ideas that explains a wide range of
observations that have been tested a lot
behavior - CORRECT ANSWER - rigid, plastic, or liquid
