BYU Earth Science Part 1 Final
questions and correct answers
Capillary attraction - correct answer ✔✔The movement of water into and through small
openings. This helps plants to get water from their roots up to their leaves
Surface tension - correct answer ✔✔The force between water molecules at the surface of the
drop. Insects use this force to "stand on" the water.
Polarity - correct answer ✔✔One side of a water molecule has a slight positive charge and the
other side has a slight negative charge. These charges cause water molecules to attract other
substances. This is similar to static cling one see in a clothes dryer. The polarity of a water
molecule gives it the ability to dissolve most earth materials.
Specific Heat - correct answer ✔✔The measure of how much heat energy is needed to warm
one gram of a substance one degree
Which process causes ocean tides? - correct answer ✔✔gravitational pull of the moon and the
sun
In what ways do the ocean and its currents affect the earth's global climate? - correct answer
✔✔Currents move cold water from the poles toward the equator, the ocean helps keep to
moderate the climate of earth, and currents move warm water from the tropics toward the
poles.
Students were asked to determine the energy in each level of the following food chain:
phytoplankton --- zooplankton ---- herring ---- pelican
Which student is correct? - correct answer ✔✔Student D
, phytoplankton: 1000 ---- zooplankton: 100 ----herring: 10 ---- pelican: 1
Which statement is false as it relates to the adaptations animals have which allows them to
survive in the deep ocean? - correct answer ✔✔They can only take the high pressure for a short
time. This is why they come to the surface each night
By far largest reservoir (recall that a reservoir is part of the earth where water is held in storage)
of the hydrosphere is... - correct answer ✔✔Oceans
How has the level of carbon dioxide in earth atmosphere changed during the last fifty years? -
correct answer ✔✔It has increased.
Which term below is not correctly matched with its definition? - correct answer ✔✔reverse
osmosis: The movement of salt into and out of living cells in the ocean
Which is a false statement about the influence of the Coriolis Effect on ocean and atmospheric
circulation? - correct answer ✔✔It is the main cause of ocean evaporation.
Which statement concerning the volume of water in the oceans over geologic time is false? -
correct answer ✔✔the volume has not significantly changed since the earth was formed
Which statement is true concerning water use in the United States? - correct answer
✔✔Agriculture uses more water than industries and homes.
Which statement below is false as it applies to wave characteristics, properties and behavior? -
correct answer ✔✔Waves are the result of the spin of the earth
Which statement below is false as it applies to the characteristics, properties and behavior of
ocean currents? - correct answer ✔✔the rotation of the earth does not affect current flow in
the oceans.
