The oceans cover approximately this percent of the earth's surface: 30%, 50%, 70% or 90%.
What is 70%?

The Coriolis effect: applies only to tides, is caused by the earth's rotation, exists only in the Northern Hemisphere
is greatest near the equator, or governs the spin direction of water draining out of a sink
What is caused by the earth's rotation?
100
This is least likely to become a fossil?
a feather, a bone, a shell, or a piece of wood.
What is a feather?
100
Most fossils are of creatures that lived in:
the sea, rivers, fresh water, or the land.
What is in the sea?
100
This ocean is the largest and has the deepest average depth.
Atlantic, Pacific, Arctic, Indian or Southern.
What is the Pacific Ocean?
200
This is why the ocean is so salty: sodium and chlorine are added by rain water,
sodium and chlorine are the elements least likely to be removed by chemical and biological processes, or
sodium and chlorine are created by marine organisms
What is sodium and chlorine are the elements least likely to be removed by chemical and biological processes?
200
These are the flattest, most featureless areas on Earth:
coastal plains, abyssal plains, continental margins or
continental slopes.
What is abyssal plains?
200
The process of identifying one rock layer with another one far away is called: correlation, connection, correspondence, or
collation.
What is correlation?
200
This is most likely to result in an organism NOT being fossilized:
rapid burial after death, preservation from decay, being a water-dwelling organism, lack of hard parts - such as bones or shells
What is a lack of hard parts - such as bones or shells?
200
The basic difference between geology and the other sciences is the element of this:
time, evolution, correlation, or experimentation
What is time?
300
This is the name for a sand ridge connecting an island to the mainland or to another island: jetty, tom bolo, sea stack,
none of the above, or breakwater.
What is a tombolo?
300
Much of the continental rise is composed of these:
calcareous ooze, sheeted dikes, submarine fans, ophiolite, or
fringing reefs
What are continental fans?
300
This is why radiometric dating is more reliable than estimating ages from rates of erosion or rates of sedimentation:
erosion is constant in rate, wind and waves redistribute the sediments, or radioactive decay is constant in rate.
What is radioactive decay is constant in rate?
300
This is what is being measured in radiometric dating:
the time when the radioactive isotope formed,
the time of crystallization of a mineral containing an isotope,
or when the stable daughter isotope was formed.
What is the time of crystallization of a mineral containing an isotope?
300
This type of salt is most abundant in seawater:
potassium bromide, sodium chloride, magnesium chloride
hydrogen borate, or sodium bicarbonate
What is sodium chloride?
400
This is the name for a circular reef enclosing a lagoon:
barrier reef, guyot, seamount, atoll, or aseismic
What is an atoll?
400
The daily tidal range is greatest during this tide:
neap, ebb, or spring.
What is spring?
400
This is what geologists call a buried erosional surface:
a paraconformity, an unconformity, a peneplain, or a conformity
What is an unconformity?
400
From the following this one is an example of a trace fossil:
dinosaur tooth, bird bone, frozen mammoth, clam shell or
worm burrow
What is a worm burrow?
400
This was the last name of the author of Principles of Geology and the principal advocate and interpreter of uniformitarianism:
Hutton, Smith, Steno, Playfair or Lyell
Lyell
Who was Lyell?
500
The energy that drives surface ocean currents such as the Gulf Stream comes from this: salinity variations, density differences, Coriolis force, wave activity, or prevailing winds.
What is prevailing winds?
500
Desalination is associated with this process:
extraction of magnesium from seawater, the formation of manganese nodules or volcanic outgassing.
What is making fresh water by taking the salt out?
500
The rate of which a radioactive element decays can be described by this:
type of element, fission-tracks, half-life of the element,
type of particle emitted, or none of these.
What is the half-life?
500
These following methods can be used to demonstrate age equivalency of rock units: lateral tracing, position in a sequence, radiometric dating, all of these or index fossils
index fossils
What is all of these?

Most "petrified wood" is an example of:
preservation of original material, carbonization, replacement,
or cast or mold
