What is science? - Answer✔the pursuit and application of knowledge and understanding of the
natural social world following a systematic methodology based on evidence
What's the scientific method? - Answer✔Testing real life theories over and over again
What is a hypothesis and what is a scientific theory (in detail); what are examples? -
Answer✔Hypothesis: Idea proposed to explain one or more facts
Scientific Theory: Structure of ideas that explains a large, diverse number of facts
The fields in Oceanography: Geology, Chemistry, etc.. how are they used within Oceanography?
What are examples? - Answer✔Geology focuses on plate tectonics
Biology focuses on evolution by natural selection
Physics focuses on gravity (law), string theory, and relativity
Astronomy focuses on the Big Bang Theory
The Earth System; The Earth's 4 spheres - Answer✔Atmosphere, Biosphere, Litosphere,
Hydrosphere
Representations of the Earth: What's a cross sectional view?
What's a block diagram?
What's a mercator map projection? - Answer✔Cross Sectional Review: "Interior" of something /
view from side as if feature were cut along a vertical lane
Block Diagram: Three Dimensional View
Mercator Map Projection: 2-dimensional depiction of our sphered Earth / distort the size of
objects in latitude from the Equator to the Poles
The 5 oceans: what is the largest and deepest and why? What is the shallowest, and why? -
Answer✔Deepest Ocean: Marianna Trench (WEST)
Largest Ocean: West Pacific
Shallowest: Arctic because no trenches, surrounded by "shelves of continent"
Know the ocean facts that we listed - Answer✔Water on Earth:
97% ocean (salt),
2% ice
1% rivers, lakes, in atmosphere (Not as huge as ground water), 2/3 of the last 3% frozen
(Antarctica) (Greenland)
Land - elevation above sea level,
Ocean
- depth below sea level (71% of earth's surface),
- light blue: shallow (edge of continent)
- dark blue / purple: deepest region (adjacent to land) (rim of fire)
- mountain volcanic belt: seperate baja california
- roughly 3.8km/12 1/2k feet
- Sea floor about 4.5k years old, oldest ocean is 200 mil < x
- about 4 billion years old - data from rocks
- average temperature -4C / 38F
- abundant elements: O(2), H(2)O, Cl, NaH(2)O
Physical Science Concepts:
What's energy?
What are the 2 types of energy we covered?
How are heat and kinetic energy related... how do you apply them to oceanography? -
Answer✔capacity or ability to do work - to cause matter - to cause a chain
(1) kinetic energy - energy of motion (Everything that moves)
(2) Heat Energy - energy produced by the red molecular motion - from hot to cold (could never
be opposite)
Thermodynamics - follows whats hot to what's cold
What are the sources of heat energy for the Earth? - solar and geothermal, explain - Answer✔(1)
Sun radiation - (solar)
(2) Interior radiation of the earth (Core and mantle)
(geothermal)
