What is heat capacity? The number of heat units needed to raise the temperature of a body
by one degree.
What is Salinity? The amount of dissolved salt in the water.
Calcium Carbonate compound that makes up all shells of mollusks and coccolithophores
Biogeneous sediments from the remains of living organisms
Sorting process of selection and separation of sediment grains according to thier grain size
(or grain shape or specific gravity)
Wentworth Scale sorts particles by size Ex: boulders, cobbles, pebbles, granules, sand, silt or
clay
Cosmogeneous sediments from asteroids and space dust
Precipitate solid that forms and settles out of a liquid mixture
Continental Drift the theory that crustal land plates are in motion (floating) and moving on
the surface of earth
The oceans of the earth cover ______% of its surface. 71%
What is Ferdinand Magellan's claim to fame? First to circumnavigate the world.
What is Leif Erikson's claim to fame? Discovered Greenland and North America.
, What are the differences between continental and oceanic crusts? continental is less dense
but thicker and oceanic is thin and dense.
Define Subduction Boundary. One plate pushes under the other.
Define Transform Boundary. When the plates push together to form mountains or trenches.
Define Divergent Boundary. When the plates separate from eachother.
How is tectonic plate motion/movement currently calculated? Satellites.
What are Stromatolites? The most primitive form of life with a fossil record.
What underwater geographical feature contains the deepest part of the oceans? Mariana
Trench.
What does O.H.E.C. stand for? Observation Hypothesis Experiment Conclusion.
Independent Variable the thing you change in an experiment to test the hypothesis
Control Group used to compare the independent or dependent variables
Scientific Method a set of guidelines that are used by scientists to answer questions about
or figure out how things work
Dependent Variable it depends on the independent variable
