EXAM SCRIPT COMPLETE QUESTIONS AND
VERIFIED ANSWERS
◉ lithosphere & asthenosphere. Answer: What two layers are part of
tectonic plate motion?
◉ continental drift hypothesis. Answer: - the precursor to Plate
Tectonics
- developed by Alfred Wegener
◉ divergent. Answer: spreading ridges are features that occur at
what type of plate boundary?
◉ tectonic plate. Answer: a rigid portion of the lithosphere that
deforms locally at its boundaries and moves horizontally
◉ divergent boundary. Answer: plates moving away from each other
◉ convergent boundary. Answer: - plates come together
- creates mountains & island arcs
,◉ transform boundary. Answer: - plates slide past one another
(vertically)
- no creation nor destruction of crust
◉ normal magnetic polarity. Answer: north seeking remnant
magnetism points towards present day north
◉ reverse magnetic polarity. Answer: north seeking remnant
magnetism points towards present day south.
◉ positive magnetic anomalies. Answer: passing over a rock and its
remnant magnetism adds to the present-day magnetic field
