Oceans 100 Exam 1 SDSU|88
Questions and Answers
SCIENCE - -supports the explanation of the natural world that best explains
all available observations (What is the basis of science? NEEDS EVIDENCE)
- SCIENTIFIC METHOD - -The process by which scientists take data from
natural world and try to answer questions.
- HYPOTHESIS - -A tentative, testable statement about the general
phenomena observed OR an initial idea of how, or why things happen in
nature.
- SCIENTIFIC THEORY - -Structure of ideas that explain a wide range of
observations from our natural world *additional facts about the scientific
theory: rigorously tested, parsimonious, and includes evidence
- The fields in Oceanography - -Geology, Physics, Biology, Astronomy,
Chemistry, Geography
- Geology - -Plate tectonics, rock types, sediment, dating of ocean floor
- Physics - -Relativity
- Biology - -Evolution by natural selection
- Astronomy - -Gravity
- Chemistry - -ph Levels of Ocean
- Geography - -PANGEA
- The Earth's 4 spheres - -Atmosphere, Biosphere, Lithosphere, Hydrosphere
- ATMOSPHERE - -air that surrounds the earth; layer of gases
- BIOSPHERE - -all living organisms on earth
- LITHOSPHERE - -uppermost rigid, outer part of earth [crust and upper
mantle specifically]
- HYDROSPHERE - -all water on earth's surface
, - Cross Sectional - -view from side, as if feature were cut along a vertical
plane
- Block Diagram - -three dimensional view
- Mercator Map Projection - -the typical, flat map we see, also exaggerated
at the poles
- ARCTIC - -shallowest. why? because it has the most continental shelves.
- ANTARCTIC - -
- INDIAN - -
- ATLANTIC - -
- PACIFIC - -largest + deepest. why? because it has the most trenches.
- -average depth of ocean - -3,800 meters
- -age of seafloor - -180 million years old
- -oldest + Deepest - -= Mariana Trench (11,000 meters)
- -average temperature - -4ºC | 38º F. why? b/c the sun only affects first 200
meters
- Age of ocean - -4 billion years old
- Most abundant elements in the ocean - -oxygen, hydrogen, sodium,
chloride
- ENERGY - -capacity to do work
- 2 Types of Energy - -Kinetic energy & heat energy
- KINETIC - -movement of motion with anything that has a mass and speed
- HEAT - -movement from heat to cold through kinetic energy
- Thermal Expansion - -if water is: warm, density is: less, energy is: high,
where: equatorial/subequatorial regions
- Thermal Contraction - -if water is: cold, density is: high, energy is: low,
where: polar/subpolar regions
