The magnetic north pole has remained very close to the geographic North Pole through all of geologic time
Paleomagnetism confirms that at particular times in the geologic past Earth has had more than one magnetic north pole.
The magnetic field of the Earth reverses itself each time that magma erupts at a mid-ocean ridge.
Fossils found in sediments can be used to:
a. indicate the relative age of the sediments.
b. provide evidence for plate movement.
c. suggest ancient climate characteristics.
d. support the idea that land masses were joined.
All continents fit together with the least number of overlaps and gaps when the continents are matched along
contours at around 2000 meters in depth
Fossils of ancient polar plants are currently found near the equator because the:
plants lived near the poles, but land masses have drifted to current locations
All of the following provide evidence for continental drift
a. age of selected continental rocks.
b. apparent polar wandering.
c. location of coral reef fossils.
e. shape of continental margins.
Continental drift was confirmed through the use of the
location of alternating magnetic polarity of seafloor rocks
Which of the following statements best describes the relationship between Earth's geographic and magnetic poles?
The magnetic pole wobbles, but stays near the geographic pole.
Vine and Matthews determined that new ocean floor was being produced at ocean ridges by examining
the magnetic pattern on the seafloor.
The seafloor magnetic pattern is be best described as:
parallel to and symmetric about ocean ridges.
Moving from oceanic ridge to oceanic trench, the thickness of the lithosphere
increases in proportion to the distance
Which of the following is associated with convergent plate boundaries on the seafloor
crest of the mid-ocean ridge
Which of the following is characteristic of oceanic-oceanic convergent plate boundaries?
volcanic island arcs
Which of the following is characteristic of oceanic-continental convergent plate boundaries?
