Oceanography-100 SDSU Exam 1
(SacramentoGrilo)
Science - -the world is understandable, interpretations are modified as
knowledge continues
- Scientific Method - -a method of procedure that has characterized natural
science since the 17th century, consisting in systematic observation,
measurement, and experiment, and the formulation, testing, and
modification of hypotheses.
- hypothesis - -a supposition or proposed explanation made on the basis of
limited evidence as a starting point for further investigation.
- scientific theory - -structure of ideas that explain wide range of
observations, supported by evidence from the natural world, rigorously
tested. Ex: plate tectonics, natural selection, big bang theory
- Big Bang - -the basis of astronomy
- Fields in Oceanography - -geology, geography, biology, chemistry,
physics, astronomy
- geology - -sea floor tectonics
coastal processes
sediments
hydrologic cycle
- geography - -wind belts
weather
coastal landforms
world climate
- biology - -fisheries
ecological surveys
microbiology
marine adaptations
- chemistry - -dissolved components
temperature dependence
stratification/density
chemical tracers
- physics - -currents
, waves
sonar
thermal properties of water
- atmosphere - -the sky. made of nitrogen and oxygen
- biosphere - -all life on earth
- hydrosphere - -all water on earth
- lithosphere - -all land on earth
- cross sectional view - -view from side as if feature were cut along a
vertical plane
- map view - -view from directly above
- block view - -three dimensional view
- mercator map projection - -map view of world but not true to size,
stretches the poles out causing them to look larger than they really are; 2D
view of a 3D object
- five oceans - -Pacific, Atlantic, Indian, Arctic, Southern
- pacific ocean - -largest and deepest because of subduction which causes
deep sea trenchs
- arctic ocean - -smallest and shallowest because it has the most
continental shelves
- how old is the sea floor? - -200 myo
- how old are the continents? - -4.6 byo
- how old is the earth? - -4.6 byo
- how old are the oceans? - -4.6 byo
- what percent of the water on earth is in oceans? - -97%
- energy - -the capacity to do work or transfer/produce heat
- kinetic energy - -energy of motion
- heat energy - -movement of molecules; the heat flow from hot to cold
