The ____ ____ theory explains that new oceanic lithosphere is formed
| | | | | | | | | | |
along oceanic ridges; the seafloor here is elevated due to the magma,
| | | | | | | | | | | |

| | | | | | | | | | | |
ridge. - CORRECT ANSWER✔✔-seafloor spreading
| | | |
Declination is: - CORRECT ANSWER✔✔-the angle between the
| | | | | | | |

,Inclination is: - CORRECT ANSWER✔✔-the angle a magnetic (compass)
| | | | | | | | |
needle makes with a horizontal plane| | | | |
The historic idea called ____ ____ says that the Earth once had a
| | | | | | | | | | | | |
supercontinent named Pangaea that has broken up and moved over | | | | | | | | | |
time. - CORRECT ANSWER✔✔-continental drift
| | | |
The Earth's magnetic poles ____. - CORRECT ANSWER✔✔-dance around
| | | | | | | |
a bit, and occasionally reverse
| | | | |
The ring of Fire describes the active volcanoes located around the edge
| | | | | | | | | | | |
of the ____ Ocean. - CORRECT ANSWER✔✔-Pacific
| | | | | |
Which of the following describes oceanic trenches? - CORRECT
| | | | | | | | |
ANSWER✔✔-Some are found next to continents | | | | |
and |
they are long and deep.
| | | |
What is the physical relationship between the geographic and magnetic
| | | | | | | | | |
north poles? - CORRECT ANSWER✔✔-They are usually in different
| | | | | | | | |
places, as the magnetic pole does move.
| | | | | |
Plate tectonic theory is based on the premises introduced by Wegener's
| | | | | | | | | | |
____ drift. - CORRECT ANSWER✔✔-continental
| | | |
, Large amounts of data concerning the ocean floor were first collected
| | | | | | | | | | |
____. - CORRECT ANSWER✔✔-during World War II
| | | | | |
Which is older: oceanic crust or the continents? - CORRECT
| | | | | | | | | |
ANSWER✔✔-The continents are older. | | |
The contracting Earth model hypothesis was used by early scientists to
| | | | | | | | | | |
explain the different features on Earth's surface. Which of the following
| | | | | | | | | | |
were parts of this possible explanation? - CORRECT ANSWER✔✔-All
| | | | | | | | |
features on Earth are approximately the same age, ocean basins are
| | | | | | | | | | |
formed due to surface collapse, and mountain belts result from the
| | | | | | | | | | |
Earth cooling and contracting over time.
| | | | |
A fundamental change in our understanding of a basic concept is called
| | | | | | | | | | | |
a ____ shift. - CORRECT ANSWER✔✔-paradigm
| | | | |
Why did most scientists not agree with the continental drift theory? -
| | | | | | | | | | | |
CORRECT ANSWER✔✔-Wegener was not a well-known scientist, he
| | | | | | | |
used deductive reasoning, which was not the norm at the time, and he
| | | | | | | | | | | | |
could not provide a sound explanation for how the continents moved.
| | | | | | | | | |
Alfred ____ was the first person to develop and publish a sound
| | | | | | | | | | | |
explanation for the origin of the continents and oceans. - CORRECT
| | | | | | | | | | |
ANSWER✔✔-Wegener
