Which of the following statements regarding waves approaching a coast is FALSE? - Answers Waves
speed up when approaching the beach.
Atoll, barrier, and fringing describe different types of ________. - Answers Coral reefs
Which of the following statements about beach drift and longshore currents is TRUE? - Answers Beach
drift transports sediment in the same direction as does longshore current.
The salinity of oceans vary from 34 to 37 parts per thousand. What is the definition of salinity? - Answers
Grams of dissolved ions in 1 kilogram of solution.
Which of the following statements about the deepest ocean layer is FALSE? - Answers Also known as the
thermocline transition zone
Why does ocean water have higher salinity in subtropical regions than along the equatorial belt? -
Answers Evaporation exceeds precipitation in the subtropical region, whereas the reverse occurs along
the equator.
Which of the following statements is NOT true regarding surface water in the oceans? - Answers Most
surface water originates near Greenland and Antarctica and afterwards flows as surface water towards
the equator.
What are the two most abundant ions in seawater? - Answers Sodium and chloride
Which of the following statements is TRUE? - Answers Global sea level has risen and fallen many times
throughout Earth history.
For incoming ocean waves approaching a coast, which of the following wave forms occur closest to the
beach? - Answers Surf
A _______________ is a bowl-shaped depression at the head of an alpine glacial valley that feeds the
glacier with snow. - Answers Cirque
, Which of the following features of an Alpine glacier is (are) formed by sediment deposition rather than
erosion? - Answers Lateral moraine
The figure below illustrates features associated with a continental glacier. Which of the following letters
corresponds to the outwash plain? - Answers A
Ice cores recovered in Greenland and Antarctica provide a record of changes in atmospheric
temperature and compositon dating back to over 100,000 years ago. Based on ice core data, which of
the following statements is TRUE? - Answers Atmospheric temperature has been steadily increasing over
the last 12 thousand years and we are presently in an interglacial cycle.
Changes in the tilt angle of Earth's rotational axis occurs approximately in _________ year cycles -
Answers 41,000
An elongated, cigar-shaped feature deposited by a continental glacier and oriented parallel to the
direction of glacial flow is called a __________________ - Answers Drumlin
Millennial climatic oscillations that occur over time periods of several thousand years or less are mainly
attributed to - Answers Ice sheet instabilities and changes in thermohaline circulation patterns in oceans
How does the collision and assembly of continents promote global cooling over time scales of millions of
years? - Answers More mountains create more alpine glaciers that increase Earth's albedo
Studies of cores obtained from continental glaciers and deep-sea sediment indicate that... - Answers All
of the above
Which of the following events MOST-LIKELY occurred during the last ice age when glaciers reached
maximum extent ~18,000 years ago? - Answers Plants and animals characteristic of colder climates
migrated southward to lower latitudes
How could sunspot activity possibly affect Earth's atmosphere? - Answers Greater sunspot activity
increases the solar wind, which in turn warms Earth's upper atmosphere
Which of the following examples will result in positive feedback? - Answers Climate cooling increases
the snow cover on land, thus increasing global albedo and causing more solar radiation to be reflected
back into space
Sea ice and ice shelves in the Arctic and Antarctica have increased in area over the past two decades in
spite of recent global warming. - Answers False
Stratified drift is most likely deposited by ___________ - Answers Glacial meltwater
Which of the following statements best describes an esker? - Answers Sinuous, narrow ridge of coarse
sand and gravel formed by a meltwater stream that flowed beneath a glacier
