What was the contribution of Fred Vine and Drummond Matthews to the Theory of Plate Tectonics. Question options: the mapping of the sea floor the mapping of tectonic plates confirming plate tectonics with satellites and lasers
recognizing the symmetry of geomagnetic anomalies on sea floor discovering convection tion 4 / 4 point A zone of earthquake foci near a deep trench, ranging from deep to shallow in a landward direction (Benioff Zone or Wadati-Benioff Zone), is good evidence for: Question options: a subduction zone a tsunami a molten outer core the Mohorovicic discontinuity a rift zone tion 4 / 4 point The term "reverse polarity" refers to: Question options: geomagnetic reversals a type of fault movement times when the climate was warm at the Earth's north and south poles rocks that do not fit with plate tectonic theory direction of flow of a convection current tion 3 / 3 point The pattern of magnetic anomalies on the seafloor most resembles:
stripes perpendicular to the mid-ocean ridges spots concentric circles around hot spots none of the above tion 4 / 4 point The rising part of a convection cell would be found beneath: Question options: mid-ocean ridge subduction zone rift valley a and b a and c tion 4 / 4 point Geoscientists have developed a magnetic reversal time scale. They know that the Earth's magnetic field reversed its polarity from studies of: Question options: magnetization of basaltic rocks and radiometric dating deep drilling and study of magnetization with depth chemistry of deep sea basalts changes in the direction of magnetic north as indicated by compasses over the last 100 years ice cores in Antarctica tion 4 / 4 point Which is a line of evidence for plate tectonics? Question options: fossil distribution shape of continents paleoclimatic evidence age of sea floor all of the above tion 4 / 4
point The boundaries of the tectonic plates are best delineated using which one of the following:
